Guardian UK reports that core has melted through reactor pressure vessel at Fukushima Daiichi Unit 2
The Guardian UK is reporting that a core melt has breached the Unit 2 reactor pressure vessel at Fukushima Daiichi Unit 2 in a lava-like formation that has flowed into the drywell which is the component of the reactor containment structure. The drywell is reportedly now filled with seawater, however, the overall containment structure very likely was ruptured by a hydrogen gas explosion on March 14. While all three reactor Units 1, 2 and 3 are reported to have extremely high levels of radioactive water outside containment in the turbine halls, Unit 2 is leaking high level radioactive water into groundwater offsite now discovered in a trench that opens on the shore of the Pacific Ocean. TEPCo workers and Japanese Defense Forces have been sandbagging around the trench openning to stave off flushing the reactor's radioactive contents into the ocean.
U.S. agencies continue to say "no harm to human health" even as Japanese radioactive releases from the Fukushima reactors literally rain down on some U.S. states. However, it is important to bear in mind that (a) there is no safe dose of radiation - this is supported by the National Academy of Sciences (b) Any additional and unnecessary exposures to radiation are potentially harmful and (c) the so-called "safe dose" calculation is based on the amount of radiation a healthy, white male in his 20s and 30s could tolerate. The same dose inflicted on a child, a pregnant woman or a fetus is far more harmful.
Official statements - which must be treated with some skepticism - now declare aerial radiation levels at Fukushima as 100,000 times "normal" with readings of 1,000 millisieverts an hour. A dose of 100 millisieverts a year is considered the threshold above which there is a risk of cancer. Again, the are calculations, not measurements and dose rates are generally not based on the most vulnerable such as pregnant women, unborn fetus and small children.
Air is also measuring 4 times more radioactive than under normal operating circumstances. The radioactive water is believed to be from the core of Unit 2 Fukushima Daiichi reactor. Seawater is highly contaminated. At least 17 workers have been acknowledged to have suffered severe radiation exposure. The situation continues to worsen at this slow, deadly disaster with no end in sight.
TEPCO officials claim the 10 million reading was "an error." Credible? Likely not. Is TEPCO interested in saving lives or saving face?
