On , the same Fukushima I-2 reactor experienced a loss-of-power accident. According to Citizens’ Nuclear Information Center, “On June 17, Tokyo Electric Power Company’s Fukushima I-2 (BWR, 784MW) scrammed due to a problem with the generator. Power was lost for a time, because the switchover to the offsite power supply was unsuccessful. As a result, the feedwater pump stopped and the water level in the reactor core fell about 2 meters. The emergency diesel generator started up just in time, so the Emergency Core Cooling System was not activated. The water level was restored by an alternative pump in the core isolation cooling system.”
