24 Feb (NucNet): Tokyo Electric Power Company (Tepco) said today its staff at the Fukushima-Daiichi nuclear station had guidelines on how to determine that a nuclear reactor is melting down, but that operators failed to use them properly as the accident unfolded in March 2011.
Tepco said in a statement in Japanese on its website that operators did not thoroughly check the guidelines and failed to determine that core melt was a possibility.
Tepco said laws, regulations and internal rules have been amended and retraining has been carried out, but admitted it needs to further improve its efforts to disseminate information about failures at the time of the accident.
