Abstract

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.

연구용원자로에서 여러 수조 및 일차냉각계통 내부에 존재하는 냉각재를 정화시키기 위해 설치되는 수조수관리계통은 일차냉각계통 펌프가 정지한 후 원자로에서 발생하는 노심 붕괴열을 제거한다. 또한, 작업수조 내의 조사물과 사용후핵연료저장조 내에 저장된 사용후핵연료에서 발생하는 열을 제거하여 수조수의 온도를 제한 값 이내로 유지하는 기능도 수행한다. 본 연구에서는 수조수관리계통의 설계와 운전 방법을 설계 초기단계에서 결정하기 위해서 상용프로그램인 Flowmaster를 이용한 전산해석방법으로 수조수관리계통의 열교환기를 설계하고, 각 수조수의 온도를 시간에 따라 예측하였다.
