Title: Assessment of residual heat generation at cyclic operation of a research reactor as input data for thermal hydraulic calculations and safety analysis
Keywords: residual heat generation, IRT-2000 reactor, IRT-4M LEU fuel,

Abstract: A review was made of the methods for analysis and evaluation of the residual heat generation in the reactor core after a certain uninterrupted period of operation. We have considered a possible approach to solving the problem for residual heat generation assessment at cyclic mode of facility operation, i.e. after several periods of operation and idle time. The input data preparation for thermal hydraulic calculations used for nuclear safety assessment is discussed. The study of the process is necessary for evaluation of the nuclear safety in case of black-out accident and/or loss of the forced reactor core cooling. The presented approach is applied to evaluate the residual heat generation in the reactor core in the reconstruction design of the nuclear research reactor IRT - 2000, Sofia, Bulgaria, configured with LEU fuel IRT - 4M (19.75% U235). The residual heat generation is estimated for the reactor core as a whole at operating power of 1000 kW in the end of the last working day aft
