Reliability of decay heat removal is an important safety consideration in the Gas-Cooled Fast Breeder Reactor (GCFR). The design evolution of the residual heat removal (RHR) systems over the past few years has been markedly aided by system reliability analyses and has resulted in design improvements which greatly reduce the probability of a loss of coolable core geometry. This evolution consisted partly in improvements to the main loop residual heat removal system because analysis of an early design of the GCFR main loop residual heat removal system has shown that its reliability was substantially limited due to single failure points both in the BOP portion of the power conversion system as well as in the support systems. As a power result, 16 improved main loop residual heat removal options were identified and analyzed for their potential to improve heat removal train reliability.
