[[[ They'll probably wash a lot of it into a drain and out into the
Sea of Japan, and a lot will also evaporate (that's why the
containers had "tightly" sealed lids in the first place). The
preferred "solution" to pollution is dilution, in their eyes. They
use it whenever possible. -- Ace ]]]

[[[ Every SCRAM is violent, as I stated. If a reactor has more than
one or two in a year, that's officially cause for concern. More than
a dozen or so over two decades is also cause for concern. Slamming
on the brakes, shutting everything down, changing the thermal and
flow characteristics of about a hundred thousand gallons of
fast-circulating, boiling-hot, pressurized, continuously-reheated
water, cooling the metal pipes, etc., is NOT easy on the
system. And to SCRAM the reactors just when they're needed most,
right after an earthquake!
Here are some additional problems with SCRAMs, and control rods in particular:
On April 6th Hitachi submitted a document revealing an additional
incident involving TEPCO. In October 1988, one of the 185 control rod
drive mechanisms in the Fukushima II-4 reactor was out of order.
TEPCO requested Hitachi to inscribe the serial number of the out of
order control rod drive mechanism onto a new one and load it without
subjecting it to the required government inspection. Two of the four
people involved in this incident are still working at TEPCO. The
power company and manufacturer were fully aware that their action was
illegal when they conspired to deceive the government, but the
government's nuclear safety inspectorate was incapable of uncovering
When three control rods fell out of position at Hokuriku Electric's
Shika-1 reactor in 1999, criticality continued uncontrolled for 15
minutes. In 1978, five rods fell out of position at reactor number 3
of Tokyo Electric Power Company's Fukushima I power plant. On that
occasion criticality continued for seven and a half hours. And in
1998 34 rods slipped 15 cm out of position at Fukushima I unit 4,
although the reactor did not reach criticality.
... And should I mention the illogical design of the control rods is
considered a "prime suspect" as one of the (many) "root causes" of
the Chernobyl disaster? They were designed with a tip which actually
increased the reactivity before decreasing it! It was no cause for
concern most of the time, but it proved to be a crucial difference
April 26th, 1986. But of course, I can't expect a pro-nuker to
remember anything that far back or in a foreign country. -- Ace ]]]

[[[ As I pointed out, simply providing the Becquerels is an
incomplete expression of the danger. But sure, 90,000 is only about
13 times your own personal "normal" dose of "background"
radiation. But that "normal" dose kills some percentage of us,
too. The 90,000 Bq. should cause pause on principle, but no one
thought it was really that, anyway. No one but a pro-nuker, that
is. However, at the NIRS web site when I checked yesterday, the
current figure was given as 402 million Becquerels. Quite a leap up,
but certainly not in an unexpected direction, considering the 63 (up
from 50 in my article) different significant problems identified so
far (not including delayed and dishonest reporting). Would your
pro-nuker hold THAT much radiation in his hand, absorb it into his
lung, store it in his gonads, feed it to his wife or infant daughter,
for it to lodge in THEIR reproductive organs, to harm yet another
generation? And what right did we have to burden humanity with
90,000 Bq, anyway? If they were long-lived isotopes, this
"punishment" will last a correspondingly long time, poisoning people
(and other living things) for eons. But 402,000,000 Bq. -- and
climbing -- ought to give anyone pause. -- Ace ]]]

[[[ The effects ARE continuing to this day -- and will continue for
generations to come. These insults are undeserved. My opposition
to nuclear power is based on logic, reason, science and
humanity. I'm not the one doing any worshiping or propagandizing --
they are. They worship the Demon Hot Atom, and Demonize all who
stand in their way. We don't call pro-nukers a "Nuclear Mafia" for
nothing. -- Ace ]]]

[[[ There is little question the Japanese nuclear industry is even
MORE corrupt and dishonest than our own -- perhaps even rivaling the
Russian or French nuclear industries. Many local residents have
wanted the Kashiwazaki facility shut down for years. -- Ace. ]]]
