Kyodo News – “The operator of the crippled Fukushima Daiichi nuclear power plant said Wednedday that the temperature of water inside the No. 4 unit’s spent fuel pool rose to 42 C as of 5 p.m. following problems with the water circulation system pumps.
One of two pumps which stopped was later reactivated, and the water temperature is expected to start falling, said Tokyo Electric Power Co. spokesman Junichi Matsumoto. On Tuesday morning, the water was 34 C. There are two pumps to cool water which is used to remove heat emitted from the spent nuclear fuel stored inside the No. 4 reactor’s pool. But the main pump stopped working on Tuesday, and the backup pump stopped on Wednesday.”
