Docket ID: NRC-2025-0975-0001 comment submitted by Ace Hoffman

re: Docket ID NRC-2025-0975 (as described in recent NRC hearings and in this pdf: https://www.nrc.gov/docs/ML2620/ML26208A059.pdf )

Comment submitted by: Ace Hoffman, Carlsbad, California USA NRC tracking number msl-6mkd-vnai

Executive Order (EO) 14300 is a dramatic and dangerous overreach of Presidential ("Executive") authority, and follows dozens of other EOs issued by the current administration which have had a devastating effect on American citizens, our trading partners, our allies, our environment, and billions of people around the world.

The corrupt Trump Administration (aka "Regime") has used EOs:

* To cancel global aid to foreign countries (including life-saving medicines and food);

* To start wars without Congressional approval (by simply not calling them "wars");

* To hamper citizens' right to vote;

* To expel hard-working and honest immigrants who have no criminal record;

* To personally enrich himself, his family, friends, and hundreds (or even thousands) of associates and "business" partners.

* To reduce health care for millions of Americans;

* etc.

And yet EO 14300 may be the MOST devastating EO of them all, because EO 14300 is intended to relax numerous nuclear safety standards and eliminate others entirely.

EO 14300 asserts that its purpose is: "modernizing reactor licensing, safety oversight, and siting practices" but that just hides what it is really doing: Eliminating safety clauses from numerous parts of 10 CFR (specifically impacting Parts 10, 50, 51, 52 and 54, and perhaps others).

Regarding Early Site Permits (ESPs), NRC-2025-0975, as a proposed response to EO 14300, will "eliminate expiration dates and renewal requirements." An example of why this is a bad idea is that nuclear reactors are extremely risky ventures and thus, invariably are sited away from large cities (even though that's where most of the electricity they produce goes). They also should not be located beneath major airport flight patterns (to reduce the chance of an accidental or intentional airplane strike such as the United Parcel Service flight 2976 crash less than a year ago). Populations change over time, and with no expiration date or renewal requirements, none of these changes would be taken into account.

Regarding extending the Manufacturing License (ML) duration to 40 years, this encourages reactor builders to continue building older reactor designs even if newer designs appear to be safer, more reliable, more efficient, etc.. Proving new reactor designs is extremely difficult and time-consuming due to the nature of radiation, which can enhance normal aging through very complex interactions at the molecular level, depending on fuel type, emission types (alpha, beta, gamma, x-ray, neutron...), energy levels, enrichment levels, and many other factors. There are currently dozens of proposals for completely new reactor designs (mostly for Small Modular Nuclear Reactors (SMRs)). Granting 40-years licenses in such a volatile field discourages innovation. In the nuclear industry, even small safety improvements can have enormous payback for society if it can prevent even ONE accident that is severe enough to invoke the use of the Price-Anderson Act.

Delaying the initial license renewal 20 years, and then doubling its time period from 20 years to 40 years is essentially an insane option. Numerous major parts of a nuclear reactor rarely or barely last as long as 20 years, such as Reactor Pressure Vessel Heads, Steam Generators, valves, pumps, backup generators, control cables, steam and water pipes, grates, filters, transformers, cement, electronics, computers... Preparation for getting a license extension is traditionally and invariably a time of repair, replacement, fix, renew, retrain, etc.. Cut out the license renewal and many of these problems revert to the standard: "fix-on-fail" philosophy, which has already been shown to miss problems that come up regularly: For example the Davis-Besse reactor in Ohio had a problem with clogged filters for many months before a worker leaned against a control rod (not a proper procedure but Ohio is very lucky it happened!) and it bent over, because a rust hole the size of a football in the RPVH had gone all the way through to the thin stainless steel liner that covers the inside of the reactor — and the liner was already bulging out!

Whoops there goes Ohio (nearly)!

The NRC on-site inspectors should have recognized a problem needed to be solved because of all those clogged filters. The company should have recognized the problem for sure, since they were buying extra filters and replacing them unusually frequently.

Both checks failed and there was nearly an unstoppable meltdown at Davis-Besse, but the incident shows the value of having competent inspectors (and concerned company employees). Ideally, the system works because the presence of inspectors not only helps find problems, but also: Their mere presence (and DILIGENCE) causes company employees to be more diligent too. At least, that's how it's supposed to work.

Another example of the importance of independent inspectors (and by extension, license renewals) is the formation of the NRC in 1974, which happened because the original Atomic Energy Commission (AEC) was found to be biased and company-serving instead of serving the public. Safety was being compromised. The AEC was pushing, funding, and supporting nuclear power's development, and at the same time was responsible for regulating safety for the same industry.

It was realized that "safety" was falling behind because the AEC was making sure the vast public, private, and government investment in the nuclear industry was showing a profit.

This author was born in 1956, and thus when the NRC was formed, was a high school senior — who actually believed that the formation of the NRC would mean the end of the nuclear industry. My thinking at the time was simply that if the NRC's purpose was solely to consider safety, it would not allow a single civilian nuclear reactor anywhere. I thought then (and think now) that reactors are too risky, and the potential consequences of an accident are far too devastating.

At that time, drone warfare, terrorism, sabotage, disgruntled workers, accidental airplane strikes (let alone 9-11 type events), etc. were distant considerations compared to simply worrying about "Normal Accidents" of the kind described in a famous book with that title, written by Charles Perrow in 1984.

But as time has shown, the NRC, regardless of its original purpose (to protect the public) has to a large extent cowered before the powerful nuclear industry — not completely (not yet, that is) — but Three Mile Island's (TMI's) accident five years after the NRC was created showed that the problem had not been solved by then, and Davis-Besse's near-catastrophic 2002 "hole in the head" incident (mentioned above), and dozens of other VERY CLOSE CALLS, have proven the real problem — that a tragic American meltdown is inevitable sooner or later — has NEVER been solved. Nor can it be, nor need it be, because there are safe alternatives that CANNOT have a huge accident and DO NOT require their own Price-Anderson Act to protect their industry from catastrophic damage expenses.

And after so many decades, WHY is there even a Price-Anderson Act at all?

Hasn't the industry learned how NOT to have a catastrophic accident? Is the industry unable to purchase insurance on the open market? Yes, of course it is impossible, for two reasons:

First, no insurance company wants to have anything to do with nuclear power precisely because it is too risky. (Go check your home-owner's policy and see that anything nuclear is specifically excluded.)

Second, to insure a nuclear reactor, the insurance company would need to believe that the reactor was safe and worth the risk. It would need to inspect it, and know what it was inspecting, and inspect it again regularly, and look at its books to be sure events are being recorded properly... and the NRC is already supposed to do all that.

Five years after it was formed, TMI proved the NRC wasn't doing enough, causing the nuclear industry itself to worry about the impact of a catastrophic accident on public acceptance of the risk, and to create their own additional voluntary nuclear safety institute, the secretive Institute of Nuclear Power Operations (INPO).

Additional incidents since TMI prove that the addition of INPO has not been enough. The industry has merely been lucky since TMI. Lucky at Davis-Besse. Lucky at Vermont Yankee. Lucky at Monticello. Lucky at San Onofre. Lucky it was Fukushima across the ocean in Japan, rather than any of the nearly two dozen identical faulty GE BWR reactors still operating in America.

Regarding planned changes to 10 CFR Part 52, what is described by the NRC as "flexibility for a developer" fails to protect the public because the use of "standardized programs" will fail to account for ANY additional information gained in the field after the "standardized program" has been approved. Even the simplest reactor design is anything but simple, and its commercial lifespan will be extremely difficult to ascertain. It cannot be ascertained from the cost of production, nor from any known "perfect" AI calculation or simulation. Only time will tell, as it does in every industry on earth. Tesla expected self-driving cars by now (and a self-sustaining colony on Mars within 10 years). Indeed, the American public was promised reactors would be safe, but meltdowns happened at SL-1, Fermi 1, Santa Susanna, TMI and we have come close countless other times. We won't be fooled again!

Yet the proposed regulations would allow an AI-generated design of a reactor, that the NRC has approved because it "looks good on paper" (that's a euphemism for looking at an AI-generated screen image), to be subsequently used by other manufacturers, in other locations, without further evaluation.

Indeed, the whole idea of a COL (Combined [manufacturing] and Operating License) is absurd for anything as complex and risky as to need Price-Anderson before anyone would throw money at the venture. Not all new reactor designs can be brought up to full power in small steps — precisely because they are so small. So either they will work at full or nearly-full power... or they will not, and if not, then Price-Anderson might save the company, and the industry, but it won't help the occupants of the city and state where the failure occurs. It won't help those downwind or downstream.

("The Price-Anderson Nuclear Industries Indemnity Act was enacted into law on September 2, 1957, by President Dwight D. Eisenhower. It was added as Section 170 of the Atomic Energy Act of 1954 to facilitate the commercial development of nuclear energy by limiting the liability of nonmilitary nuclear facilities." — A current AI-generated answer (from a Brave browser).)

Regarding planned changes to 10 CFR Part 54, allowing nuclear reactor operators to propose "alternative risk-informed and performance-based criteria" to "manage" aging reactors is an alternative, presumably, to having permanent on-site inspectors from the NRC and as such, it cannot possibly IMPROVE safety, and its purpose can only be to lower costs. Does risk to life and limb or risk to corporate profits matter more? What is the proper balance for a "risk-informed" decision (see discussion of NRC's mission statement, below)? Of course, no nuclear reactor has EVER been operated for 80 years, let alone 120 or 160, and no sane person would EVER allow ANY reactor to operate that long. The ONLY possible reason to operate one for that length of time is because it seems profitable... until it breaks. And even then, there's Price-Anderson to cover the corporate costs. But what about the human costs?

If Price-Anderson MUST exist for SOME reactors, there should at least be a sunsetting of P-A support: The original 20 years should have been more than sufficient, and then only for the first few reactors. But nobody would build a reactor without it, and that doesn't make nuclear reactors safe. Nothing can make nuclear reactors safe. The NRC could have figured that out in 1974 — before Three Mile Island, Chernobyl, Fukushima, and they still can figure that out, before whatever happens next if they don't.

Regarding planned changes to 10 CFR Part 50, 52, and 53, the "flexibility" for Emergency Planning Zones (EPZs) assumes there is such a thing as a "low-risk facility." That's like saying a cyanide factory might be a "low-risk facility." By what criteria is that even possible? And regarding Emergency Preparedness (EP) generally, so-called "streamlining" the process is impossible: No two localities are the same, their wind and water patterns and needs, their population densities, the nearness to the reactor site of hospitals, schools, nurseries, farms, airports... all these things (and many more) are different at each site.

Regarding planned changes to 10 CFR Parts: 50.75, 53.1010, 53.1020, 53.1040, 53.1050, decommissioning costs are right now being stolen for foolhardy attempts to restart old reactors, and are grossly inadequate anyway unless the government promises both insurance for accidents (Price-Anderson) AND to take the toxic nuclear waste after use — or pay the waste manufacturer to store the waste on-site, possibly forever as far as we can tell so far.

Therefore, the LOCAL residents (and the whole world) are put at risk long after the reactor stops operating and income for decommissioning stops coming in. There is no plan which does not result in the public absorbing the cost of indefinite storage, OR the cost of accidents, including the costs of cancer, leukemia, stroke, heart attack, childhood deformities, premature death... and lost property values.

No reactor can be financially worth operating, starting from Day One.

Additional comments are not necessarily specific to any particular 10 CFR Part, but may relate to multiple Parts:

As long as there is no solution to the nuclear waste problem (which could be forever), what calculations are being used to determine the overall safety of any nuclear endeavor from start to finish — in other words, including mining, milling, refining, enriching, transporting, using, removing, wet storage, dry storage, transport, more dry storage, perhaps more transport and more dry storage... with a factor for risk per year multiplied by a reasonable expectation for the "worst case" scenario of UNLIMITED nuclear waste storage times, and also a calculated risk factor for a spent fuel dispersal accident at some time MUCH later in the future, perhaps a thousand years from now, or ten thousand, when the fuel will have far fewer fission products but about the same amount of plutonium-239 and uranium-235? Calculations should also be made for the risk of the fissionable isotopes being extracted from the fuel, turned into thermonuclear (Pu) or atomic (U) bombs, and then exploded on another spent fuel storage installation in the middle of a large "nuclear campus."

With more than two thousand Small Modular Nuclear Reactors (SMRs) expected (2,102 was the number estimated by the NRC recently) transportation accidents are essentially inevitable. How will it be possible to transport used SMRs intact without risking overloading old, decrepit bridges, even if those bridges successfully take normal traffic? Since these SMRs might be placed anywhere in the country, it is extremely likely that they will use bridges and tunnels and narrow roads that large heavy loads do not normally travel on. This should be recognized as a special problem because maximum SMR sizes are determined in part by the "legal" weight limits on America's highways, not the ACTUAL load limits. It's one thing to assume a potato truck or dump truck can pass over an old bridge. However, a large quantity of highly toxic nuclear waste requires a much more careful analysis of the strength of every bridge and tunnel, every steep mountain pass, and every population center, every risky intersection, every rail crossing... not to mention the skills of every operator (they must have no "loco-motive" and be licensed to operate nuclear transport vehicles, not just any shipping container or even any normal (non-radioactive) large and heavy load). The "normal" risks are multiplied by the potential damage that could affect every generation of life (human and other) for eternity. Now, THAT is a very heavy load!

Every analysis of the "risks" MUST be compared to the benefits, and THEREFORE it is imperative that the nuclear reactor risk/benefit calculations be compared to similar calculations for alternative energy sources, such as wind and solar with clean energy backup and a widespread (global) interconnected electrical energy grid such as that proposed nearly 100 years ago by R. Buckminster Fuller.

The risk comparisons must include the consequences of severe accidents in both cases, of course. Rare events must NOT be excluded, and in fact it is impossible to know the "odds" of such events as terrorism, asteroid impacts, war, accidental airplane strikes, earthquakes, tsunamis, volcanic activity, and even abandonment due to plague or some other reason. So-called "walk-away safe" reactors would have to be tested under the most extreme conditions!

The reality is that meltdowns MUST be assumed; and the potential damage to the area where the reactor will be operating and/or stored after use must be individually examined for the possible consequences of ANY severe accident.

Plutonium-239, with a half-life of 24,100 years, is a relatively easy element to extract from spent nuclear fuel to make a nuclear bomb with: A number of countries have done it, and America was terrified that Germany or Japan would do it while we were doing it during WWII, so it really can't be all that difficult for any "advanced" civilization. Therefore, it must be ASSUMED that any plutonium-239 in spent fuel COULD eventually end up being used in a thermonuclear bomb. We can pray it won't happen, but better yet we can ensure it won't happen by NOT MAKING THE PLUTONIUM IN THE FIRST PLACE. Or at least, we can stop making more.

Allowing nuclear reactors to run for 80 years or even 120 years, let alone 160 or more... is madness: Why do it? If a reactor can't pay for itself in 20 years, maybe it's NOT cost effective? If it can, does that include the cost of severe accidents? NO! Not unless America gets rid of Price-Anderson for ANY extension of the original license. Otherwise ALL the additional risks of an aging plant are forced onto the public at large. Will the nuclear industry EVER take full responsibility for the potential accidents it can create?

With 2,102 SMRs in operation for up to 120 years or more each (according to potential relicensing within the new regulatory framework) that would be more than a quarter of a million years of operation. The record of nuclear power has never been anywhere near good enough, in terms of meltdowns per total years of operation across the industry, to sustain that kind of penetration without incidents. It is therefore reasonable to ASSUME there will be severe accidents with SMRs, including a complete dispersal of the contents somewhere, for some reason, at some point in the future. Therefore the standard "reference accident" model and corresponding EPZ, etc. should be based on the health effects, financial burdens, and restricted land-use (etc.) that can be created by such an accident. With so many reactors in so many places, so-called "extremely rare" events WILL HAPPEN.

Be definition, SMRs will have much smaller, lighter, thinner reactor pressure vessels (RPVs). Therefore radiation damage to the vessels themselves may be MORE intense and MORE extensive (proportionately) than to an 8" thick current RPV. How many "coupons" will be required for SMRs? Will EVERY SMR be required to have coupons? How will the coupons be extracted? How frequently? Who will examine them to determine if any embrittlement issues have appeared? ("Coupons" here is referring to small sample nuggets which are manufactured along with the RPV, at the same time and of the same alloy as the RPV, and placed in the "hottest" (both radioactively and thermally) areas of the RPV, to be examined periodically over the planned life of the reactor, in place of destructive testing of the RPV itself.)

Should a new SMR design be certified as a design that can be replicated without "undue regulatory burden" before at least one version of the new design has been destructively tested so that the accuracy of its own coupons can be determined BEFORE large-scale manufacturing of that design occurs without "regulatory burden"?

How often will SMRs be inspected on-site? How will they be properly guarded against terrorism, sabotage, war, etc.? Will remote-controlled or automated (AI-controlled) lethal defensive weapons be used? If not, will a guard be on duty 24/7 (even if the control room operations have been handed over to AI)?

How will the local emergency responders be trained to handle the unexpectedly rare event that turns out happening anyway, somewhere, because there will be so many chances (2,102 or more)?

How will it be possible to safely move a used SMR?

Lastly, I wish to comment on the NRC Mission Statement as shown on slide 6 of https://www.nrc.gov/docs/ML2620/ML26208A059.pdf which reads as follows:

"The NRC protects the public health and safety and advances the nation's common defense and security by enabling the safe and secure use and deployment of civilian nuclear energy technologies and radioactive materials through efficient and reliable licensing, oversight, and regulation for the benefit of society and the environment."

It should first be noted that there has been a lot of "mission creep" in the 52 year history of the NRC.

The current mission statement does NOT emphasize public safety as the highest priority — rather, "enabling" the nuclear industry is the NRC's main mission. Furthermore, the claim within the mission statement that the nation's "common defense and security" can in any way be improved by the "use and deployment of civilian nuclear energy" is as preposterous a statement as can be made in a world of turmoil, drones, awkwardly-started wars with no clear conclusion, advanced weapons beyond any ability to defend against them, and actions by the current President which violate international law for open trade and seas, and even war crimes including bombing civilian infrastructure such as children's schools, and desalination plants in a desert... these sorts of actions, aside from being horrible to contemplate having been done in America's name, only portend of future retaliations if history has taught the world anything — and that retaliation will be at any future date, time, and place. Nuclear reactors are already considered hostages throughout the world: In Ukraine, six have been captured by Russian forces, and the Chernobyl containment has been breached by missiles and continues to spew deadly radiation. Other reactors around the world are being threatened on a daily basis.

Furthermore, the purpose of civilian nuclear reactors is ONLY to produce electricity: Their ONLY connection to "security" is to be a primary target of terrorists or opposing forces, or even to be potentially accidental targets of mistakenly aimed (or damaged-in-flight) missiles that were meant for the cities nearby.

Furthermore, even ONE EMP (Electro-Magnetic Pulse) from ONE nuclear warhead exploded high above the atmosphere over the central portion of the United States could cause a COMPLETE BLACKOUT throughout the country, causing ALL electrical transmission systems to fail simultaneously, INCLUDING nuclear power plant control rooms and ALL backup systems, resulting in nearly a hundred simultaneous meltdowns and shortly thereafter, accompanying spent fuel pool fires as the pool's water boils away. Military reactors may or may not be similarly damaged: Full testing of supposedly "hardened" facilities is impossible.

Furthermore, plans to operate SMRs with operator-less remote AI-control introduces enormous security problems including external breaches by other AIs and internal rogue systems. Pushing AI control into current reactor control rooms adds the danger of human operators losing their own skills as they rely on and trust the AI more and more over time, until the moment that trust becomes poorly placed.

These vulnerabilities will NEVER go away, they will only get worse, especially if there are thousands of Small Modular Nuclear Reactors (NRC 's current estimate is 2,102) spreading throughout the country, crisscrossing the fifty states (53 states if Puerto Rico becomes a state (as it should), and Canada and Greenland are annexed (as the current occupant of the White House has repeatedly asserted is his desire).

Finally: Nuclear energy is the most costly, most environmentally-unfriendly, slowest-to-achieve energy solution available among the non-fossil fuel choices, due to its cost-of-failure (requiring public insurance in the form of Price-Anderson), its likelihood of failure (far from zero), its unreliability (unexpected failures often result in months or years of downtime), and then the nuclear waste is left for someone to find... for hundreds of thousands of years (plutonium-239).

Civilian nuclear power is utterly unsustainable, ESPECIALLY in a world with nuclear weapons.

WSJ jumps the shark claiming: "An Underground Nuclear Reactor Is Coming to This Kansas Town—and Dividing Locals"

I've made a few comments in Bold. No words in the original article have been removed, although the images are not included (other than an icon-sized version of the frontispiece) (I may add my own images later.)

An Underground Nuclear Reactor Is Coming ("Is Coming" As if it's a foregone conclusion) to This Kansas Town—and Dividing Locals

No one has tried operating a commercial reactor a mile down—until now. (As if it's already happened.) "It's great that it's here. It's kind of bad that we're the guinea pigs."

By Kris Maher and Jennifer Hiller, Wall Street Journal, July 28, 2026

https://www.wsj.com/us-news/climate-environment/an-underground-nuclear-reactor-is-coming-to-this-kansas-townand-dividing-locals-7cd558a3

PARSONS, Kan.—Residents of this sleepy farming outpost agree on many things. But whether to put an experimental nuclear reactor a mile deep in the granite beneath their town isn’t one of them.

Elected officials and some others see a chance to create jobs and lure data centers and manufacturers to a rural patch whose economy has been flatter than the surrounding cornfields. Another group is effectively saying “not under my backyard.” (No! They're saying: "WTF?")

“I put $125,000 into my house, and now a nuclear reactor is coming to town,” said Jerel Johnson, an IT professional who planned to retire in Parsons. “I can’t think of a worse idea.”

No one has tried operating a commercial nuclear reactor deep underground—until now. The so-called Gravity Reactor is the creation of Liz Muller and her father, Richard Muller, emeritus professor of physics at University of California, Berkeley and an inventor. (Invented what, a hole in the ground?) They founded Deep Fission, a three-year-old California startup that has raised around $150 million in the past year, including $40 million last month through an initial public offering, largely to fund the work in Parsons.

Parsons, with a population of 9,600, sits about midway between Kansas City and Tulsa, Okla. Deep Fission drilled a first test hole (HOW DEEP DID THEY GO?) this spring on 100 acres at a mostly overgrown industrial park dotted with old munitions bunkers just outside town.

On a recent day, Maurice LaFountain, Deep Fission’s senior engineering director, showed off pink-flecked granite retrieved from the company’s first test hole and joked that the billion-year-old rock would make a nice countertop.

An empty steel canister sat on a cleared drill pad, waiting to go down a second hole this year (How far down?). The plan is to send another one loaded with nuclear fuel (As if going from a steel canister, to an operational nuclear is a small step. Will the steel canister have the tubing that will be used for the reactor going down a full mile? Will they try retrieving it? Does it weigh half what a reactor will weigh?) into a third hole to heat water a mile underground and generate electricity on the surface in 2027 or 2028—an astonishingly short time frame by industry standards. (Why three different holes? (Just curious. Thirty holes wouldn't be enough proof the idea is even half sane to me!) How wide and how deep will each be? And why isn't that information included in this stupid article?)

Verlyn Bolinger, an insurance agent who sits on the Parsons city commission, as his great-great-grandfather did, is now mostly excited by that prospect. (An insurance salesman, huh? Has he heard of Price-Anderson?)

“Any time you’re putting a nuclear reactor in a hole, it’s kind of scary,” he said in his office, surrounded by Kansas City Royals memorabilia. “It’s great that it’s here. It’s kind of bad that we’re the guinea pigs.” (See how that worked out for the citizens of the Bikini Atoll... https://acehoffman.blogspot.com/2026/07/book-review-bomb-by-theodore-taylor.html )

A push for a ‘nuclear renaissance’

The project is riding momentum from the Trump administration’s efforts to usher in a “nuclear renaissance” by streamlining regulations and offering the industry billions of dollars in loans and fuel supply-chain investments. Executive orders President Trump signed last year aim to quadruple America’s nuclear-power generation by 2050—a steep climb given that construction in the industry has slowed to a crawl for the last three decades; nuclear generates about a fifth of U.S. electricity. (LESS THAN a fifth -- and shrinking as renewables + storage is faster, cheaper, easier, safer, MORE RELIABLE and vastly more environmentally friendly.)

The renewed interest comes amid soaring electricity demand, much of it driven by data centers for artificial intelligence.

Deep Fission’s project is one of 11 in an Energy Department pilot program designed to build and test small, advanced reactors to pave the way for commercial use. Participating companies can construct reactors outside a traditional national laboratory setting and use expedited procedures for environmental reviews. (New designs by companies that have never built a reactor and an expedited environmental review -- what could possibly go right?)

Deep Fission is part of a project designed to build and test small, advanced reactors to pave the way for commercial use.

“It’s allowing us to develop a first reactor within a time frame that had been unthinkable previously,” said Liz Muller, Deep Fission’s chief executive.

Four startups, including one from a separate DOE program, say they have achieved criticality, or self-sustaining nuclear reactions, with their reactor designs. Deep Fission’s is using a common, scaled-down, reactor design; its innovation is putting it underground. (That is hardly the only difference. Size matters, and margins of error matters too.)

The key to the plan is avoiding the need for hulking containment buildings. Instead, the mile-deep hole will provide the necessary pressure, cooling and containment. (Presuming rocks with no fissures and they won't crack from the heat or be damaged during drilling.) A single reactor will generate just 15 megawatts, enough to power about 12,000 homes, but Muller envisions an array of 100 or more (Think of the maintenance problems!), providing more than a gigawatt, enough for a data center (Let the cat out of the bag). The Nuclear Regulatory Commission would oversee approval of commercial licensing, needed to sell electricity. (Is that the ONLY reason the NRC is "needed"???)

Dozens of firms are designing smaller reactors and a handful have begun construction, but none yet operate commercially in the U.S. Companies like Deep Fission must prove they can meet short timelines, contain costs and overcome the industry’s historic challenges. (How can they prove any of this before actually operating the reactor and damn the torpedoes, full speed ahead!)

Nuclear watchdogs say the administration is moving too fast and cutting corners. This spring, 12 attorneys general argued that circumventing standard environmental reviews would put communities at risk, among other things. (A nuclear accident could affect multiple states and ultimately, the entire world.)

Deep Fission drilled a first test hole for its nuclear reactor this spring on 100 acres at an industrial park outside Parsons.

“It’s simply unacceptable to even consider exempting Deep Fission from a peer-reviewed environmental impact statement on the generation of high-level nuclear waste under Parsons,” said Paul Gunter with Beyond Nuclear, a group that opposes nuclear power and weapons. (If the WSJ thinks nuclear weapons are relevant to this discussion, they should include the word "proliferation".)

The Energy Department said the administration remains focused on safety and security. (Ignoring cost and all the clean alternatives that don't require safety and security considerations at all.)

Liz Muller said Deep Fission’s plan to store spent fuel underground is safe. (Did she provide any documentation proving this absurd statement?) Eventually it could seal it in place or move it to another site (Uh huh. Sure. Just pick it up and move it. Careful: It's HOT!). She and her father previously founded Deep Isolation, which designs underground disposal of nuclear waste. (And these are used where? Nowhere.)

Deep Fission plans to open a Parsons office where locals can ask questions, she said. The project “needs to be done in partnership with the community and sort of their own vision for their economic development.” (One guard on site (MAYBE) and the rest is automated (the always-reliable AI?). Not many jobs after construction.)

Parsons: looking for a spark

When Deep Fission broke ground (HOW DEEP did they dig so far? When constructed, what portion will be lined, and with what (if any will be)?) in December, some residents were shaken. The Great Plains Industrial Park, a decommissioned U.S. Army ammunition base, had approved the project without public discussion.

Marjorie Reynolds, a pediatric nurse, quickly formed a nonprofit, the Prairie Dog Alliance, to oppose the project. Its logo is a prairie dog in a black-and-yellow nuclear symbol.

Reynolds worries about environmental oversight and potential risks to water. She questions how the company will perform maintenance underground, and why drillers are operating under oil-and-gas regulations, not nuclear ones. If Deep Fission were to go out of business, what then?

Marjorie Reynolds formed a nonprofit to oppose the nuclear project. She worries about environmental oversight and potential risks to water.

“This is a nuclear experiment,” said the seventh-generation Kansan, who hands out donated patches that say “half lives matter” and “remember Chernobyl.”

Muller said Deep Fission’s reactor is too deep to affect aquifers (What's the proof of this statement? And how do they drill a hole past where aquifers might be without risking contaminating that aquifer? (If that part is lined, with what and how thick will that lining be?)), and that it will follow all nuclear and oil-and-gas regulations. Its reactors are expected to last six to seven years, she added, so the likelihood of maintenance is low. “There’s not a lot of moving parts that require maintenance. We have simplified our reactor quite extensively.” (A: SHOW US. B: What if maintenance IS required? What's that going to be like with 100 holes filled with reactors? How many operators? AI only? Testing/training AI properly beforehand will be impossible; being sure it is scalable will also be impossible; being sure it won't "escape" its rules and misbehave will also be impossible.)

Parsons was a 19th-century boomtown with one of the largest rail yards west of the Mississippi. A tornado tore through in 2000 (So the entire topside can be wiped away because there's no big strong building up top. What happens down below after that happens up top?). These days, officials point to small economic victories like attracting a Taco Bell and saving a furniture store. They have plans to build housing behind the bowling alley. All they need is people to move here.

Wayne Gilmore, an optometrist who owns the local radio station that broadcasts high-school football games, doesn’t want to miss a potential economic boon (A "boom" is a better word.). “Rural communities cannot build their futures by rejecting new technology before it’s evaluated,” he said. (A optimistic short-sighted optometrist.)

Robert Spinks, Parsons’s police chief, said he isn’t worried about potential contamination and thinks the reactor could be the spark the city needs when energy is a big draw.

Robert Spinks, Parsons’s police chief, thinks the reactor could boost the city as energy demand grows. (It's planning to have one very risky customer: A data center.)

“It’s a proven technology, just in a new application,” he said. (He's being misled.) “And if that is a trigger which draws in other manufacturing and brings in living-wage jobs, I think that’s a win.” (No discussion of the many very real issues that this nutty idea has to overcome...)

To Whom It May Concern,

In my opinion there are numerous problems with the Deep Fission reactor concept. I've listed a few of the most obvious ones:

1) It will have two cables, each one mile long, for placing and possibly retrieving the unit. Since reactors are extremely dense and heavy items, the possibility of a cable break should not be ignored. If one cable breaks or merely stretches a smidgen more than the other cable, the reactor will likely turn sideways and jam in the hole. This could happen near the surface or deep inside the hole. Furthermore, one dropped bolt, wrench, brick, rock etc. could ruin everything.

2) Multiple holes, if they are close together, could mean a single reactor meltdown and steam explosion could affect nearby reactors. And the proper definition of "close" is very uncertain.

3) Mile-long drill holes can collapse at any point, making retrieval and operation impossible.

4) If the control rods cannot be inserted for any reason, a meltdown situation could happen essentially forever.

5) It does not appear that the holes will be lined in any way. Natural fissures could cause large rocks to come loose, or the drilling process itself could loosen chunks of the walls. Perfect smoothness would require numerous tool bit changes, increasing the cost significantly. Will they use dull drill bits to save money during construction (when no income is coming in and costs mean everything)?

6) Earthquakes can destroy every borehole at once, causing as many meltdowns as there are reactors. Even a fraction of an inch misalignment could mean the reactor(s) could NEVER be retrieved or serviced.

7) If water intrusion occurs from an unrealized already-existing deep fissure, everything goes boom and continues to spew radioactive steam essentially forever. Plugging up the hole would be extremely difficult, unlikely to be permanent, and only means the underground area would continue becoming the most polluted place on earth. Any warning signs above ground would not last nearly as long as the waste would be toxic, spreading, and unmanageable.

8) If either the downspout or the steam pipe breaks anywhere along the mile-deep tubing, it may be impossible to retrieve anything below the break point.

9) The only way for this to pay back the builders and operators is to run these reactors for a long, long time. Pulling any reactor up to inspect/repair it means pulling up the entire mile-long tubing, which means the entire tubing must be sectioned and separable. Each joint has to be 100% leak-proof. How many sections do they plan to have? (For example: If each segment is 50 feet tall (about five stories), they would need more than 100 segments for each fission reactor, with more than 100 leak-proof joints.)

10) Operating reactors need electrical control cables as well as steam and water piping. These cables, dropping a mile straight down, will have to remain in perfect condition and be retrievable along with the reactor. Running right next to the hot steam and water is a very unsafe place for electrical cables. (Imagine a surface reactor having to run its electrical system right next to its primary coolant pipes.)

There are undoubtedly many other problems with ANY deep-borehole reactor design, but these come to mind — without even requiring any deep-thought!

(All quotes below are from https://www.thebrighterside.news/post/a-nuclear-reactor-buried-one-mile-below-ground-moves-from-concept-to-a-kansas-test-site/ )

Test wells: "... intended to collect geological, hydrological and thermal information ..." The company admits they don't have enough data yet to know if this is the least bit feasible.

The project is already behind schedule: Plans called for criticality by July 4, 2026, instead they delivered a "prototype reactor canister" on July 7, 2026. Expect schedule slippage throughout the project.

"The company argues that relying on familiar components could reduce technical uncertainty compared with developing an entirely new reactor system." But in fact, they ARE developing an entirely new reactor system which cannot be properly tested on the surface (because it has no containment, and because pressures and thermal conditions are different, etc.). Additionally, the site-specific environment is completely without precedent. It's a crap-shoot.

*****

Interesting how these two quotes admit the company is concerned about hazards the industry and the NRC has always dismissed:

"... would operate far from storms, aircraft and most surface activity."

"...hurricanes, tornadoes, floods, tsunamis and aircraft crashes. Surrounding rock would provide a physical barrier against surface hazards and deliberate attacks." How is a mile-deep hole protected from floods? And if the reactor is so safe, why are they seeking (and presumably won't move forward without) Price-Anderson insurance protection?

*****

The author of the article doesn't seem to have considered the dichotomy of the following two quotes:

"Regulators must also examine how the design would manage groundwater, drilling conditions, heat removal, radioactive material and emergencies deep underground."

"The reactor would remain attached to cables. Deep Fission says operators could raise it to the surface in one or two hours if inspection became necessary." That timing sounds extremely optimistic.

And even supposing they could raise the reactor to the surface (despite all the potential for something to get stuck) how would they propose to work on, or transport, an unshielded reactor? Or even inspect it?

*****

Lastly: How sure is anybody that there is no problematic residue in the area left over from the previous uses of this site? Given that this was a munitions manufacturing site, what happens if they already have reactors in the ground and they hit unexploded munitions while drilling another hole?


At the NEIS Night With The Experts mentioned above, Dave Lochbaum pointed out that dropping a nuclear reactor a mile is not a good idea, but certainly would be possible if this project moves forward.

Book Review: The Bomb by Theodore Taylor (1995) reviewed by Ace Hoffman (July, 2026)

The Bomb is a fictional account based around real events: Preparations for the first post-war atomic bomb test, which occurred July 1, 1946 in the South Pacific.

The bomb referred to in the book's title was called Able, a plutonium bomb similar to Fat Man — the bomb that destroyed Nagasaki the previous August. Able was the first in the Crossroads series of test bombs and the fourth atomic bomb ever exploded. Theodore Taylor was a U.S. Navy veteran who participated in preparations for the Able test. Nearly 50 years later, he wrote The Bomb.

Crossroads required the displacement of the Bikini Atoll's inhabitants, who had called their "string of pearls" home for many generations.

Bikini had provided the islanders with everything they needed: Coconuts for food and drink, pandanus leaves to make shelters to live in and mats to sleep on, abundant fish for nourishment. They knew how to survive the occasional tropical storms that blew through the area (climb the palm trees and hang on for dear life). The only thing they couldn't control were outside military forces: First the Spanish, then the Germans, then the Japanese, and finally the Americans, who saved them from the cruel Japanese, only to remove them from their home a few months later.

The Bomb's characters are based on Taylor's experiences meeting the islanders while serving on board the destroyer USS Allen M. Sumner, which entered the Bikini lagoon about six months before the Able blast, to prepare the atoll for the tests to follow -- and to remove the islanders, who were "gently" persuaded to leave voluntarily*.

The inhabitants of Bikini were told they would be taken care of. They barely were. They were told they would be able to go back. Some finally went back, but ten years after their return, diseases brought about by the lingering radiation made them leave again (those that had not died in the meantime). The islands of the atoll are still uninhabitable due to high levels of radiation — except by wildlife that doesn't know any better, since radiation is odorless, tasteless, and colorless. It is an invisible killer around us all, all the time.

Each chapter of The Bomb is preceded by a brief description of actual events: The discovery of fission, the establishment of The Manhattan District, the Trinity test, the bombing of Hiroshima and Nagasaki, the end of World War Two, the arrival of the Sumner, the placement of dozens of ships and thousands of caged and penned animals to see how they would survive (or more likely, not), the atomic bomb blast and radiation effects.

The Bomb became historically significant because it was a best-seller that discussed the horrific after-effects of nuclear war, which are due to the radiation that is left behind. The book is a warning to all of us that future wars will continue to damage and kill for thousands of generations afterwards, from the Cesium-137, the Plutonium-239, and a rainbow of other radioactive elements every nuclear bomb blast releases into our tiny blue planet.

Nowhere on earth is truly isolated: Earth is a closed system. However, in 1946, it was generally assumed that low levels of radiation were actually harmless. Thousands of studies since that time have consistently shown a "Linear, No Threshold" (LNT) relationship between radiation dose and the likelihood of its causing harm to living organisms.

Bikini was considered far enough away from every other inhabited land mass that the poisons would either be harmless or only cause harm in statistically insignificant amounts.

Later in the Crossroads test series, a Japanese fishing trawler called The Lucky Dragon was twenty miles outside of the exclusion zone for the "Castle Bravo" blast, and a hundred miles away from Castle Bravo's epicenter — but downwind. What looked like snow to the sailors fell on the boat, and nearly every sailor on board became violently ill. One died after they had returned to Japan.

What America and other countries did by testing so many nuclear weapons in the South Pacific and elsewhere was unconscionable and unnecessary. People all over the world will continue to suffer from the fallout of the Crossroads tests and from every other bomb test since Trinity. Fish, crustaceans, aquatic mammals and other sea creatures will also continue to suffer and die for an eternity from these "tests."

People around the world protested against the Crossroads tests. In the novel, even before their exile is accomplished, nearly all of the islanders wished that they had not agreed to go so readily. The survivors today feel the same way.

But in 1946, less than a year after the world's most brutal war (so far) had finally ended, America desperately wanted to know EXACTLY what an atomic bomb could do to a navy. Pearl Harbor was barely five years earlier and nobody had forgotten it. Would the ships survive? Would surviving sailors be able to fight? Would they be able to have children later?

Results were presumably very disappointing — far worse than expected.

* Reviewer disclosure: Many years ago, this reviewer, a computer programmer by trade, was "gently" persuaded to sell software for use by the U.S. government, and thus is well aware of what sort of effort can go into such "gentle" persuasion (they got my software, and as far as I can tell, they've been using it ever since).
