Selected Safety Aspects of WWER-440 Model 213 Nuclear Power Plants

In 1991, the Atomic Energy Commission (AEC) of the former Czechoslovakia requested that an evaluation of the safety aspects of the WWER-440 model 213 nuclear power plant be undertaken under the auspices of the IAEA. The request for this study was a logical progression from the activities related to the accident analysis of WWER type reactors that had been originated under the IAEA Technical Co-operation Regional Programme in 1985 and carried out until 1990 with the participation of Bulgaria, the former Czechoslovakia, Hungary, Poland and the former USSR. The prime objective of the Project was to co-ordinate and integrate assistance given to national organizations in studying selected aspects of safety for the same type of reactors. Consequently, the study integrated these results. This report provides a comprehensive review of the conduct and the final results of the Project. It summarizes both the detailed material published earlier in IAEA-TECDOCs Nos 742, 803, 810, 811 and 848 and other material. It will be useful to everyone working in the field of WWER safety, and in particular to experts planning, executing or reviewing studies related to WWER safety.
