TEPCO says cooling interruption of spent fuel pool at Fukushima Daini Unit 1 due to human error

Tokyo Electric Power Company (TEPCO) announced on July 29 that the event in April 2026, where the spent fuel pool cooling system at Unit 1 of the Fukushima Daini Nuclear Power Plant was shut down for approximately 32 hours, was determined to be caused by human error. At the time of the incident, the plant was in the decommissioning phase. On April 5, a fault alarm was triggered by the cooling water circulation pump of Unit 1 at Fukushima Daini. After on-site personnel confirmed smoke from the equipment, the pump was stopped, resulting in an interruption of the spent fuel pool cooling system for about 32 hours. TEPCO previously stated that the cause was damage to the cable connecting the pump motor. According to TEPCO's latest explanation, the cable melting may be related to the installation method when the cable was replaced in 2012...
