Tokai Nuclear Plant, Japan's first nuclear power station
The Tokaimura nuclear accidents refer to two nuclear related incidents near the village of Tōkai, Ibaraki Prefecture, Japan. The first accident occurred on 11 March 1997, producing an explosion after an experimental batch of solidified nuclear waste caught fire at the Power Reactor and Nuclear Fuel Development Corporation (PNC) radioactive waste bituminisation facility. Over twenty people were exposed to radiation.
The second was a criticality accident at a separate fuel reprocessing facility belonging to Japan Nuclear Fuel Conversion Co. (JCO) on 30 September 1999 due to improper handling of liquid uranium fuel. The incident spanned approximately 20 hours and resulted in radiation exposure for 667 people and the deaths of two workers.[1] Most of the technicians had to go to hospital with serious injuries.[2]
It was determined that the accidents were due to inadequate regulatory oversight, lack of appropriate safety culture and inadequate worker training and qualification. After these two accidents, a series of lawsuits were filed and new safety measures were put into effect.
By March 2000, Japan's atomic and nuclear commissions began regular investigations of facilities, expansive education regarding proper procedures and safety culture regarding handling nuclear chemicals and waste. JCO's credentials were removed, the first Japanese plant operator to be punished by law for mishandling nuclear radiation.[3] This was followed by the company president's resignation and six officials being charged with professional negligence.
