Fukushima's radioactive seawater in the Pacific |
The news coming out of Japan these days is not good.
The Japanese government confirmed that the crippled Fukushima
Daiichi nuclear plant has been leaking an estimated 300 tons of radioactive
water into the Pacific Ocean each day. The leaks have apparently been going on
since the March 2011 earthquake and tsunami that caused three reactors in the
plant to melt down.
Japan’s Nuclear Regulation Authority (NRA) called the situation an
emergency and Prime Minister Shinzo Abe called it “an urgent problem.” The
consensus among independent scientists is that Tepco, the plant’s operator, is
incapable of stopping the discharge into the sea, which it has kept secret for
more than two years.
It was discovered after the NRA detected strontium and tritium in
a monitoring well at the plant site.
But it gets worse.
On Aug. 14, Tepco began preparing to remove 400 tons of “highly
irradiated” spent fuel from the severely damaged Reactor Four building.
The operation is set to start in November and expected to take one
year. A removal has never been attempted on this scale and, according to
nuclear experts, “is fraught with danger, including the possibility of a large
release of radiation if a fuel assembly breaks, gets stuck or gets too close to
an adjacent bundle,” the news agency reported.
The radiation contained in the fuel pools in Reactor Four is
equivalent to 14,000 times the amount released in the atomic bomb attack on
Hiroshima.
In their World Nuclear Industry Status Report 2013, independent
scientists Mycle Schneider and Antony Froggat wrote: “Full release from the
Unit-4 spent fuel pool, without any containment or control, could cause by far
the most serious radiological disaster to date.”
In other words, the devastation would be worse than Chernobyl and
far worse than the 2011 Fukushima meltdowns, although no one can say how much
worse.
The operation is necessary, however, because scientists estimated
that the chance of Fukushima being hit by a magnitude 7.0 earthquake was 98 per
cent within three years. Another quakecould cause the fuel pool structure to
collapse and start another chain reaction.
The seriousness of the situation cannot be overstated. A host of
observers have called for a team of the world’s top scientists to take over the
entire clean-up, especially in light of Tepco’s miserable track record of
missteps and misinformation.
This week, however, Japan’s nuclear regulator approved a plan for
Tepco to carry out the clean-up that will take 40 years and cost billions that Tepco
said it doesn’t have.
Canadian health officials assure us that there is nothing to worry
about from radioactive water pouring daily into the Pacific. Friends, the danger of “radiological disaster” from
Reactor Four is real. For the Japanese it’s a living nightmare, and for the
west coast of North America, it is a legitimate threat.
