Radiation Level At Fukushima Reactor No. 2 At Its Highest Level Recorded So Far, Neutron Beam Observed 13 Times
Wednesday, March 23, 2011
Per the Japan Nuclear Agency: the Radiation level at Fukushima reactor No. 2 at its highest level recorded so far. From Reuters: “Radiation at the crippled Fukushima No.2 nuclear reactor was recorded at the highest level since the start of the crisis, Japan’s nuclear safety agency said on Wednesday. An agency spokesman said 500 millisieverts per hour of radiation was measured at the No.2 unit on Wednesday. Engineers have been trying to fix the plant’s cooling system after restoring lighting on Tuesday.” And some more truthy news from Kyodo:
Electric Power Co. said Wednesday it has observed a neutron beam, a kind of radioactive ray, 13 times on the premises of the Fukushima Daiichi nuclear plant after it was crippled by the massive March 11 quake-tsunami disaster.
TEPCO, the operator of the nuclear plant, said the neutron beam measured about 1.5 kilometers southwest of the plant’s No. 1 and 2 reactors over three days from March 13 and is equivalent to 0.01 to 0.02 microsieverts per hour and that this is not a dangerous level.
The utility firm said it will measure uranium and plutonium, which could emit a neutron beam, as well.
In the 1999 criticality accident at a nuclear fuel processing plant run by JCO Co. in Tokaimura, Ibaraki Prefecture, uranium broke apart continually in nuclear fission, causing a massive amount of neutron beams.
In the latest case at the Fukushima Daiichi nuclear plant, such a criticality accident has yet to happen.
But the measured neutron beam may be evidence that uranium and plutonium leaked from the plant’s nuclear reactors and spent nuclear fuels have discharged a small amount of neutron beams through nuclear fission.
