It has a power failure with the Fukushima 1st nuclear plant. 1, 3 and 4 the spent fuel pool alternative cooling system and the like of the machine stops.

18 days before 7 pm, a power outage occurs at the TEPCO Fukushima Daiichi Nuclear Power Station, Unit 1 and Unit 3, the system has stopped to cool the spent fuel pool of Unit 4 in it, TEPCO to determine the cause you had to.

Results before 7 pm April 18, a momentary power failure occurs in significant seismically isolated building has become the center of convergence of the work of the Fukushima Daiichi accident, TEPCO found out, part of the power plant is shut down I have found that.

Although it would not affect the water injection into the reactor in Unit 3 Unit 1 Unit 1 and Unit 3, the cooling system has been stopped in the spent fuel pool of Unit 4 it. Unit 1 and Unit 3, water temperature is turned 16 degrees and 25 degrees, about 0.1 degrees to 0.3 degrees per hour, in the spent fuel pool of Unit 4, the temperature rise of the house of TEPCO it is expected to be about 04 to more than 65 degrees are set forth in the provisions of the. Spent fuel pool cooling system is no prospect of recovery is standing.

The fact that there was trouble in the vicinity of the cable according to the Nuclear Regulatory Agency, led to the switchboard of the high-pressure power plant, TEPCO I are looking into the cause. In this problem, it is that change is not to the value of the monitoring posts to measure the value of the radiation that has been established in the vicinity of the nuclear power plant.

The storage pool in the No. 4 reactor building has a total of 1,535 fuel rods, or 460 tons of nuclear fuel, in it. The 7-story building itself has suffered great damage, with the storage pool barely intact on the building’s third and fourth floors. The roof has been blown away. If the storage pool breaks and runs dry, the nuclear fuel inside will overheat and explode, causing a massive amount of radioactive substances to spread over a wide area. Both the U.S. Nuclear Regulatory Commission (NRC) and French nuclear energy company Areva have warned about this risk.

If that cooling water supply is lost, it will be just a few hours at most before that waste is on fire.

Matsumura was told that if the fuel pool at unit 4 collapses or the water spills out, so much radiation will spew out for 50 years that no one will be able to approach Fukushima:

Before the Committee, Ambassador Murata strongly stated that if the crippled building of reactor unit 4—with 1,535 fuel rods in the spent fuel pool 100 feet (30 meters) above the ground—collapses, not only will it cause a shutdown of all six reactors but will also affect the common spent fuel pool containing 6,375 fuel rods, located some 50 meters from reactor 4. In both cases the radioactive rods are not protected by a containment vessel; dangerously, they are open to the air. This would certainly cause a global catastrophe like we have never before experienced.

If an earthquake or other event were to cause this pool to drain this could result in a catastrophic radiological fire involving nearly 10 times the amount of Cs-137 released by the Chernobyl accident.

It is no exaggeration to say that the fate of Japan and the whole world depends on NO.4 reactor. This is confirmed by most reliable experts like Dr. Arnie Gundersen or Dr. Fumiaki Koide.

has a margin of about four days before the temperatures would be expected to reach levels of concern.

TEPCO and the Nuclear Regulatory Agency and can not identify the cause of the Fukushima Daiichi power outage.

At the Fukushima Daiichi power outage, seems to have also stopped cooling of the shared pool. In the fuel storage pool body 6377.

One fish, a greenling measuring 38 cm in length, was contaminated with 740,000 becquerels per kg - more than 7,400 times the recommended government limit regarded as safe for human consumption.

The discovery is likely to reignite fears that Fukushima Daiichi nuclear power plant may still be leaking radioactive contamination into the ocean more than two years after it was damaged in a major earthquake and tsunami.
