The cooling system for a spent fuel pool at the crippled Fukushima Daiichi power plant’s No. 4 reactor automatically suspended operation Saturday morning after an alarm issued a warning at around 6:25 a.m., Tokyo Electric Power Co. said.
The water temperature of the pool was 31 C at the time of the suspension, and leakage of water with radioactive materials has not been confirmed, TEPCO said, adding it is unlikely the temperature will rise rapidly.
