Japan’s Nuclear Regulation Authority has issued a warning to the operator of the crippled Fukushima Daiichi nuclear power plant for not complying with rules to safeguard nuclear materials. The regulator says the company was not keeping a list of keys to the reactor buildings.
Tokyo Electric Power Company is working to decommission the plant. The company told the regulator last December that a key to one of the buildings was missing.
An investigation revealed that workers did not notice the key was missing for more than a week because there was no list of keys.
NRA officials found more than 9,000 keys to open another padlock on a door of the reactor No.1 building.
The officials say they will abide strictly by the rules to protect nuclear materials.
