Lessons drawn from safety related incidents in nuclear power plants

Ten most significant events with regard to nuclear safety are reported which occurred in the operation of Czechoslovak V-1 and V-2 nuclear power plants in Jaslovske Bohunice and Dukovany in the years 1982-1987. Also discussed are the observed trends of other nuclear safety events. It is stated that the operation of Czechoslovak nuclear power plants is safe and reliable but that the process of the continuous rise in the total safety level must not be interrupted. A comparison of Czechoslovak units with units in other countries shows that the safety level of Czechoslovak units is not lower. The importance is emphasized of the analysis of events in foreign nuclear power plants and of subsequent application of recommendations based on such analysis, in Czechoslovak nuclear power plants.
