Yankee terrorists...

February 14th, 2010

Dear Readers,

Vermont Yankee Nuclear Power Plant is leaking copious quantities of tritium, a relatively rare (in nature) and extremely hazardous radioactive isotope of hydrogen. Tritium can be absorbed through the skin, as well as ingested or inhaled.

Water from test wells around the Vermont Yankee reactor has over 2 million picoCuries of tritium per liter -- more than 100 times the legal limit set by the Environmental Protection Agency (EPA) for tritium in drinking water, which is 20,000 picoCuries of tritium per liter (20,000 picoCuries equals about 740 radioactive decays per second (740 Becquerel ("Bq")).

Two million picoCuries per liter is nearly as poisonous as the 2.7 million picoCuries per liter that occurs in the chemical brew of a nuclear reactor's primary coolant loop.

Nuclear reactor operators are allowed to release a small fraction of a teaspoon of tritium offsite per year. But even that tiny amount must be diluted in billions of gallons of water to meet the legal standards for drinking water. If the water in your body was polluted with tritium at the legal limit, it would contain about 400 times the average concentration of tritium in the human body.

Tritium has a half-life of about 12.3 years, meaning half of any given quantity of tritium will decay in that time and in the next 12.3 years, half of what is left will spontaneously decay, and so on. It takes about 20 half-lifes (about 250 years) for any spilled tritium to be eliminated from the environment.

By definition all hydrogen has one proton, but the tritium isotope also has two neutrons in its core and is unstable -- radioactive. The most common isotope of hydrogen is stable and has no neutrons. Hydrogen with one neutron in its core, called deuterium, is also stable.

The body cannot detect the difference between radioactive tritium and stable isotopes of hydrogen (nor can it distinguish radioactive isotopes of any other elements from stable isotopes of the same (or chemically similar) elements).

When a tritium atom decays, it releases a beta particle. Beta particles are normal electrons, except they are traveling at very high speed (within a few percent of the speed of light). The beta particle immediately starts to slow down as it passes things with electrical charges -- other negatively-charged electrons and positively-charged protons.

Beta particles only exist for a fraction of a second. Tritium's beta particle typically travels less than a millimeter through human tissue before it is slowed to normal electron speeds and is captured by something needing an extra electron.

The nuclear industry likes to point out that tritium's beta decay particle is a "low energy beta particle." That's true, as beta particles go. But here's what the nuclear industry doesn't like to tell you about "low energy beta particles": They are essentially just as dangerous as high-energy beta particles because nearly all the damage from a beta particle comes at the end of its travel, when it's slowed down so much that it stays near the last few thousand atoms it passes long enough to have a significant effect on each of them in turn as it passes.

Since radiation damage is often measured in total energy dumped into a given quantity of tissue, by that measure, low-energy beta particles are actually proportionately MORE damaging! Just the opposite of what the industry claims!

When the beta particle is released, one of the neutrons in the core of the tritium atom converts to a proton. With two protons and one neutron in the nucleus of the atom, the element is now a stable isotope of helium, not hydrogen. Chemically, helium won't combine with much of anything. Certainly not with a molecule comprising one hydrogen and one oxygen atom, which is what's left of the water molecule the tritium atom probably was originally a part of. The remaining "OH" molecule is a potent "free radical" which can damage your body until it is absorbed by something: Vitamin C or some other anti-oxidant, for instance.

Tritium is called an "activation product." Vermont Yankee is not only leaking tritium: Within the millions of gallons of chemically-treated and highly irradiated primary coolant loop water that has been spewing out of Vermont Yankee -- probably for years, maybe even for decades -- are undoubtedly a whole rainbow of radioactive elements, including long-lived isotopes of elements such as iodine and technetium and many others.

Fuel assemblies in nuclear reactors commonly fail by cracking slightly. The zirconium shielding deteriorates and the radioactive uranium gets out, and so does anything else inside. What's inside, besides the unfissioned uranium, are "fission products." Fission is what they are trying to do inside the reactor, enough to boil water but not enough to melt down the reactor. For every uranium atom that is fissioned, there are usually two fission products that result, each of which is radioactive and each of which weighs, on average, about half as much as the original uranium atom. All fission products are radioactive because they invariably have too many neutrons to be stable.

When setting standards, the Environmental Protection Agency (EPA) generally does not aggregate radioactive components in your drinking water. Just because you have one contaminant in your water doesn't mean you don't have many others there as well. In the case of Vermont Yankee, the pollutants presumably include strontium, cesium, and many other radioactive elements. But as long as each one has been diluted to Below Regulatory Concern (BRC), the Nuclear Regulatory Commission (NRC) doesn't care, and EPA doesn't care, and the nuclear industry certainly doesn't care. Just dilute it, and, as far as they're concerned, it disappears. Such thinking is self-serving, insulting, dangerous, and archaic. It flies in the face of the standard, accepted scientific theory that radiation damage follows an "LNT" ("Linear, No Threshold") pattern. (In fact, some experts believe low levels of radiation cause proportionately more damage. And admittedly, there will probably always be a few "experts" (usually well-paid by the nuclear industry) who "honestly" believe that low doses of radiation are actually beneficial, regardless of how randomly those doses are administered.)

The only way to clean up the radiation at Vermont Yankee is to close the plant, build a big pit somewhere where it doesn't rain much, line it with a lining that will last practically forever (good luck finding these things) and move all of the waste (including the dirt and concrete) there. But instead, right now, Vermont Yankee's tritium, strontium, iodine, technetium, and everything else WILL get into the drinking water in Vermont and into the Connecticut River. It WILL kill children and other living things in the communities downwind and downstream of the reactor, which potentially includes anywhere on Earth. Radiation from Vermont Yankee has undoubtedly been killing people for years, and it will continue to kill for many years to come even if the reactor is shut down permanently, as it should be.

Vermont Yankee is one of the oldest reactors in America. So what's happening there -- namely, it is falling apart and it's owners don't want to spend any more than they have to to keep it going -- is a precursor of what's to come at other reactors. The owner (Entergy, which is trying to sell it) claimed in sworn testimony to the people and elected officials of Vermont that Vermont Yankee was NOT leaking tritium, but they knew it was. Then they said it wasn't leaking MUCH tritium, but they knew it was. Now they say the tritium is harmless, but any sane person knows that's a lie, too.

In addition to the leaks, Vermont Yankee also is piling up enormous quantities of used reactor cores at the site. One third of the reactor core assemblies are removed every eighteen months to two years. These irradiated "hot" fuel assemblies are extremely hazardous -- ten million times more hazardous than when they were placed inside the reactor (approximately).

By now there is about a thousand tons of "spent fuel" (what an innocuous-sounding name!) located at Vermont Yankee. A fraction of a milligram is a lethal dose, if inhaled or ingested. You could not stand near the fuel for 2 seconds if it were unshielded. If it catches fire, the local fire department will not be able to extinguish the flames, and cancer clusters will appear later, as much as 500 miles (or more) downwind. A single gram of "spent fuel" would have a significant impact on Vermont and its neighboring states, were it to be released by accident or by terrorism or acts of God.

Vermont Yankee is a relatively small reactor, about half the size of more modern reactors in terms of electrical output, and it could easily be replaced by renewable options. Nuclear reactors are terrible "baseline" power sources anyway, since they are prone to sudden and prolonged shutdowns. They create, and then leak, horrifically dangerous poisons which deform our babies, give our children cancer, and can cause heart attacks, dementia, and a thousand other illnesses -- and they make other illnesses worse. Their owners lie and obfuscate, and their nuclear waste is a growing nightmare.

It's time to shut Vermont Yankee down -- and the rest of our reactors, too.

We should not put our money into Obama's misguided nuclear dementia.

February 4th, 2010

Dear Readers,

There is no such thing as safe, clean nuclear power, and there never will be. There is no such thing as safe containment of nuclear waste, and there never will be. Therefore, we should not put our money into President Obama's misguided nuclear dementia.

Did we learn nothing from 9-11? Did we learn nothing from the tsunami in Banda-Ache? Did we learn nothing from the earthquake in Japan that nearly initiated "Genpatsu-Shinsai"? Did we learn nothing from Davis-Besse's near-meltdown in 2002? Did we learn nothing from Chernobyl?

So far we have been lucky: Lucky the terrorists only flew directly over, instead of into, the Indian Point Nuclear Power Facility. Lucky the nearest nuclear power facility to the 2004 tsunami was thousands of miles away and the waves only did "minor" damage. Lucky none of the seven nuclear power plants at the Kashiwazaki-Kariwa Nuclear Power Facility melted down when a "beyond design basis" earthquake occurred in 2007. Three years later, only two of those plants have come back online. Lucky a worker at Davis-Besse inadvertently leaned against a control rod housing during maintenance, and it gave way, alerting them to the severe corrosion in the reactor pressure vessel head below them. Lucky Chernobyl happened there, not here.

Steven Chu and the entire DOE (Department of Energy) couldn't stop 9-11 style terrorists no matter how much money Obama gives them to "solve"the nuclear waste problem with so-called "temporary" onsite storage. In fact, DOE won't even try -- they say the TSA (Transportation Safety Administration) handles that. Since no planes will ever be hijacked again, they don't have to protect against airplane strikes structurally. No airplane will fall uncontrollably out of the sky onto a nuclear power plant, either -- even though numerous commercial flight paths overfly nuclear power plants around the country. The containment domes are touted as being airplane-proof but they aren't. And even if they were, MOST of the nuclear poisons at each reactor site are stored OUTSIDE the containment domes, in the spent fuel pools and dry casks. The control rooms are also outside the domes, and without the control rooms, the plants would surely melt down, releasing billions of Curies of deadly radiation.

Only geologic storage combined with constant monitoring has any hope of protecting nuclear waste from a 9-11 type of attack, and even then, rogue employees can sabotage any physical fortress.

Geologic storage also may not be able to protect the radioactive waste from earthquakes or other hazards. For the past 20 years Yucca Mountain was the presumed future national repository for nuclear waste, but it has technical flaws as well as political hurdles. Any repository will have such problems. Over time, water, rodents and insects will always move the waste out of the repository. Finding a community that accepts nuclear waste means finding a community that is desperately poor, poorly educated, and has corrupt leaders. The Yucca Mountain team was allowed to suggest anything different if they could -- just not the same thing in a different place.

Obama is correct that Yucca Mountain is a flawed solution for the waste problem, but so is Obama's current plan for spent fuel -- known as "on-site storage" -- which means dozens of different things at dozens of different reactor sites, each with a scandal behind it.

Reprocessing is intensely polluting and expensive, and doesn't eliminate the deadly fission products. And worst of all, reprocessing enables the nuclear weapons industry.

Rocketing spent nuclear reactor cores to the sun costs too much and would fail too often, because humans fail, and so do their materials. Materials ARE failing at all our old nuclear power plants, and so are the humans. Fraud, cover-ups, circular arguments, intimidation of activists, and lies are the stock-in-trade of the nuclear industry.

Radiation, heat, pressure, and vibration are all very damaging, even to so-called super-alloys. New steam generators start to fail almost as soon as they are installed, but the industry accepts this, and makes wild claims about the great research and new materials that will be used to replace the old stuff. And then they deliver the same old leaky parts made of the same old leaky materials, and that's why there is tritium (and other radioactive substances) in the groundwater under so many reactors.

Tritium is a radioactive form of hydrogen, the most common element in our bodies and in the universe. Hydrogen is used in our bones, brains, heart, blood... everywhere. The legal limit for reactors to release each year is about one thirtieth of a teaspoon of tritium, and they have to dilute even that much in billions of gallons of water before they can legally release it. Neither the Nuclear Regulatory Commission nor the nuclear reactor operators care about tritium leaks as long as the deadly pollutant is diluted to legally-dispersible (but still hazardous) quantities.

The nuclear industry assumes that a little radiation, of any type, absorbed by any part of the body, is good for you. Therefore, they believe that every release is harmless as long as it's sufficiently diluted. In reality there is no safe dose of radiation. Benefits from using radiation in medicine come at a price in cancers for some percentage of the patients later, and even in cancers for the medical personnel.

The nuclear industry and its supporters insist that renewables won't work. But wind power ALONE could supply all of America's energy needs -- with a properly-designed power grid. We need a better grid anyway, to avoid colossal blackouts like we had in the Northeast in 2003, impacting approximately 50 million people and causing emergency shut downs at dozens of nuclear power plants, when their offsite emergency backup power supplies failed. Even Obama favors investing in a better, more robust power grid.

The nuclear industry claims nuclear power can be a cure for global warming. It can't be. There are the uranium mining companies with their enormous earth-moving equipment, the construction process, the storage of the waste for millennia afterwards, the operational costs in fossil fuels for the thousands of employees at the plants, the superfund cleanup sites the nuclear fuel cycle has already created, and the hospitalizations resulting from accidental (and intentional) releases of radiation. These are all "carbon intensive" activities.

President Obama wants to invest $54 billion dollars (of taxpayer's money) in a "new" generation of nuclear power plants which will be marginally more efficient -- if that -- and marginally safer -- if that -- and dozens of times more expensive than previous generations of nuclear power plants. And they'll generate thousands of tons of new nuclear waste each year, just like the currently-operating, "old" generations of nuclear power plants do.

Instead of finally ending the senseless production of more nuclear waste, Obama has set up a new committee to "study" the waste problem for two more years. In two years, these people will throw up their arms, like everyone else before them, and declare, as quietly as possible, that they couldn't solve the problem either. But creating the committee gives the 104 currently-operating nuclear power plants a green light to keep making more waste. Over the next two years, thousands of TONS of NEW nuclear waste will be created, any milligram of which can kill, and kill, and kill, and will destroy any container you put it in.

All just for electricity (or so they say). Electricity which is easily obtained through other methods that are truly safe, clean, and green.

Sincerely,

Liberty, turned on its side...

January 10th, 2010

Dear Readers,

A few days ago I received an anonymous letter in a Southern California Edison company envelope. It concerned the behavior of a manager in the control and electrical design engineering department at San Onofre Nuclear Generating Station (SONGS).

The letter alleged "Ethical Misconduct" and was apparently sent to San Onofre's Chief Nuclear Officer and Senior Vice President, Ross Ridenoure, on Christmas Day, 2009. The letter also described a "fear of retaliation" simply for complaining.

Rightly or wrongly, the industry previously considered the pair of reactors at San Onofre to be among the best-operated in the world. The workers took pride in their "culture of safety."

Now, San Onofre is near the bottom in the industry's own self-ranking, and is under special scrutiny by the Nuclear Regulatory Commission (NRC).

And despite that scrutiny -- or perhaps in part because of it -- things are actually getting worse at the site. Extra inspections and mass firings have served only to increase the desire of the plant workers to hide their mistakes.

But what are they covering up?

Fire inspections that aren't actually being done. Emergency generator tests that aren't being carried out. Regulations that are being purposefully violated without anyone checking to see if anyone authorized the "over-ride." Dangerous ramifications that aren't being considered before projects are started. Safety lock-outs that aren't being applied to heavy machinery while people are working on it. Areas under lifts that are not roped off. Damaged cables that aren't being replaced until after a failure occurs. High-radiation operations that aren't properly staffed. (At San Onofre, "ALARA" stands for "Always Let Another Run Ahead.")

These are just the things we've eventually heard about. Undoubtedly there are many more problems.

The anonymous letter described an incident where a manager, Mr. Rak, deleted a survey from one of his employees' email, thus preventing the employee from returning a possibly-unfavorable evaluation of the manager. The survey was being conducted to fulfill NRC requirements to show that the plant was addressing their "culture of cover-up."

Certainly one of the easiest ways to introduce a statistical bias into a survey's results is: Don't let people take part in the survey if they might not answer questions the way you'd like. And this apparently happened over what the employee described as a "minor altercation." What about when things go really bad? What cover-ups occur then?

As it turns out, the answer to that question at San Onofre is also known, because of what's happened to people like Rick Busnardo: Employees who try to break through the "culture of cover-up" are denied access to email (they must put all their complaints in hand-written notes). They are also prevented from talking to their own supervisors -- sometimes for months at a time. And they -- or the departments they supervise -- are issued "Stop Work Orders" (SWOs) for no reason.

Furthermore, the official wording of any complaints that do get into the system are based on the upper-level manager's idea of how the complaint should be worded, NOT the wording of the actual complainant. So if a line manager writes that one of his employees knowingly and intentionally violated procedures, executive management can instead -- without any facts to back up their version -- describe the incident by saying that the line manager was unable to properly supervise his employees.

In the past year, I've seen or met, or received letters, phone calls, or emails, from about half a dozen San Onofre whistleblowers. This level of activity is astounding and unprecedented.

It's very hard for an outsider to know what's really happening at the plant. Secrecy is firmly embedded in the culture of nuclear energy, regardless of whether there's also a "culture of safety" at the same time. It can -- and should -- be argued that the two cultures are incompatible, and ONLY in a culture of openness can there be any hope of a culture of safety.

While recognition of the "culture of cover-up" by the NRC and San Onofre employees is new, the culture itself is not new. For example, in Spring, 2001, San Onofre employees dropped an 80,000 lb crane they were hoisting. The NRC put a slew of lawyers on the phone with me, trying -- unsuccessfully -- to get me to reveal the name of the employee who told me about the incident! The openness the NRC wants does NOT extend to the public.

Later, when I complained about numerous instances of the P.R. spokesperson for the plant lying to the media and to the public, I was told by the NRC that statements made by the public affairs officer of an NRC-licensed facility are not "regulated activities" and their veracity will NOT be investigated.

But the media will report what these P.R. spokespeople say as if they are speaking the gospel, in part because the NRC won't correct even the most blatant lies.

Nuclear power is not cheap, it's not carbon-free, and it's not safe. The waste problem is intractable. A meltdown, which can contaminate an area the size of Pennsylvania, can occur at any moment, at any plant.

Huge amounts of money are spent in back-door ways to keep nuclear power plants operating. Huge amounts of water and other natural resources are wasted every day, and huge amounts of coal and oil are burned to mine and mill the fuel that is used in nuclear power plants. Just look at the clean-up bills for our weapons sites, such as Hanford, Washington, to get an idea of what the real clean-up costs for nuclear power plants (which create even MORE waste than our military programs) will be.

Over the past four decades, San Onofre has created millions of pounds of deadly radioactive waste. These are poisons whose dangers are not diminished by baking, burning, cooling, compressing, decompressing, mixing, shocking, shaking, liquefying, gasifying, or solidifying. Poisons which physically destroy any container you put them in. (Containers which would be destroyed anyway, collapsing to dust or rusting away over the eons during which nuclear waste must be stored.)

There is no reason to keep San Onofre open any longer, and many good reasons to shut it down forever -- including the 500 NEW pounds of high-level nuclear waste it creates every day it remains operational.

Safer alternatives exist, which can provide enough jobs for every skilled and honest worker currently employed at the plant.
