Virtually every agency (including the EPA) minimized the impact from radiation through the entire crisis. Now we have a peer-reviewed study revealing that they were f.o.s. all along "This study of Fukushima health hazards is the first to be published in a scientific journal. It raises concerns, and strongly suggests that health studies continue, to understand the true impact of Fukushima in

The obvious lesson out of the Fukushima disaster seems to be that you can't make a nuclear catastrophe go away within a years time. Given the magnitude of the crisis in Dai-ichi, creating such an expectation would merely amount to wishful thinking. Despite Tepco's assurances that cold shutdown will be achieved by years end, it's becoming clear that the radioactive water storage situation will

Just in time to offset the Tepco Execs 'cold shutdown in 6 months' drivel, it was recently discovered that the water level in a tunnel linked to the Number 3 reactor has been rising several centimeters a day for the past week. The water is expected to rise to about one meter below the ground level soon.  It works out great.  At that rate, the highly radioactive water should completely fill the

Adding insult to  injury, farmers in Kanagawa prefecture are not only stuck with acres of unsellable, hazardous tea leafage, but have been tasked to round it all up for transportation and disposal.  NHK mentions that "The prefectural government has asked farmers to place the harvested leaves as far as possible from the trees until it decides with the central government how to dispose of them".

Once the steam is converted back to water, that water is sent back into the reactor to resume the cooling process. The piping for each task is separate, one

Unacceptably low levels of water within the unit 1 reactor pressure vessel have dogged TEPCO since the beginning of the crisis. After increasing rates of water injection for weeks on end with no appreciable increase in levels within the RPV or the containment vessel, Tepco engineers have been hard pressed to figure out where the water had gone.

Looking at the latest plant parameter data, all reactor 3 temps apart from suppression chamber are continuing to climb. Reactors 1 and 2 are also hot from a historical perspective. This is probably why the rate of water injection is higher at this particular unit vs the other two, and at last check stands at 9 cubic meters/hr.
