The pool water management system, which is installed for purification of the coolant in the pools and the primary cooling system of a research reactor, removes the decay heat from the reactor core when the primary cooling system stops. It also removes the heat generated from the irradiated objects in the service pool and the spent fuels in the spent fuel storage pool to keep the temperature of the pools within a limited value. In this study, the heat exchanger of the pool water management system is designed by CFD method using a commercial code Flowmaster, and the temperature of the pools is estimated along the time to conclude the design and operation method of the pool water management system.
