Abstract

A process heat exchanger (PHE) in a nuclear hydrogen system is a key component for transferring the considerable heat generated in a very high temperature reactor (VHTR) to a chemical reaction that yields a large quantity of hydrogen. A performance test on a medium-scale PHE prototype made of $Hastelloy^{(R)}$-X is scheduled in a small-scale gas loop at the Korea Atomic Energy Research Institute. In this study, as a preliminary study before carrying out the performance test in the gas loop, high-temperature structural analysis modeling and macroscopic thermal and structural analysis of the medium-scale PHE prototype by imposing the established displacement boundary constraints were carried out under the gas loop test condition. The results obtained in this study will be compared with the performance test results of the medium-scale PHE prototype in the gas loop.

수소를 대량으로 생산하기 위한 원자력수소생산시스템에서 공정열교환기는 초고온가스로로부터 생성된 초고온 열을 화학반응공정으로 전달하는 핵심기기이다. 한국원자력연구원에 구축되어 있는 소형 가스루프에서 $Hastelloy^{(R)}$-X 로 제작된 중형 공정열교환기 시제품에 대한 성능시험이 계획되어 있다. 본 연구에서는 중형 공정열교환기의 고온구조건전성을 파악하기 위한 선행 연구로서 소형가스루프 시험조건하에서 중형 공정열교환기 시제품의 고온구조해석을 이전 연구에서 확립된 경계조건을 적용하여 수행하였다. 해석결과는 소형가스루프에서의 중형 공정열교환기 시제품에 대한 성능시험 결과와 비교할 예정이다.
