Title: Safety analysis method in case of black-out accident on pool type research reactor
Keywords: black-out accident, safety analysis method

Abstract: The presented method is intended to be used for the evaluation of the operating parameters influenced by processes in a pool type research reactor in case of black-out accident. For this initial event a systematic deterministic analysis under the assumption of a single independent failure in one of the safety systems has been prepared. The ongoing processes are defined in the scenarios examined. Each of the processes - the heat carrier movement in the primary coolant circuit by its own momentum, the residual heat generation in the nuclear fuel at cyclic operational mode of the facility after several periods of operation and idle time, the natural circulation thrust caused by the residual heat generation after the reactor scram system extinction of the fission reaction and the temperature fields distribution are described mathematically by engineering-applied formulas.
