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.
