초록

초고온가스로로부터 생성된 $950^{\circ}C$ 정도의 초고온 열을 이용하여 수소를 경제적이며 또한 대량으로 생산하려는 원자력수소생산시스템에서 중간열교환기는 원자로에서 생산된 초고온 열을 수소생산 공장으로 전달하는 핵심 기기중의 하나이다. 한국원자력연구원에서는 초고온가스로에 사용될 핵심 기기에 대한 성능시험을 위해 소형가스루프를 구축하였고 중간열교환기의 유력한 형태로 고려되고 있는 인쇄기판형 열교환기의 소형 시제품을 제작하였다. 본 연구는 인쇄기판형 열교환기 소형 시제품을 소형가스루프에서 시험하기 전에 루프 시험조건하에서 인쇄기판형 열교환기 소형 시제품의 고온 구조건전성을 미리 평가하기 위한 작업의 일환으로 수행한 결과, 즉 고온 구조해석 모델링, 거시적 열 해석 및 구조 해석 결과 등을 정리한 것이다. 해석 결과는 인쇄기판형 열교환기 소형 시제품 성능시험결과외 비교하고 향후 제작될 중형 시제품 설계/제작에 반영할 것이다.

The IHX (intermediate heat exchanger) is a key component of nuclear hydrogen systems for the production of massive amounts hydrogen. The IHX transfers the $950^{\circ}C$ heat generated by the VHTR (very high temperature reactor) to a hydrogen production plant. The Korea Atomic Energy Research Institute established a small-scale gas loop to test the performance of key VHTR components and manufactured a small-scale PCHE (printed circuit heat exchanger) prototype, which is being considered as a candidate for the IHX, for testing in the small-scale gas loop. In this study, as a part of the high-temperature structural integrity evaluation of the small-scale PCHE prototype, we carried out high-temperature structural analysis modeling and macroscopic thermal and structural analysis for the small-scale PCHE prototype under the small-scale gas loop test conditions. This analysis serves as a precedent study to scheduled PCHE performance test in the small-scale gas loop. The results obtained in this study will be compared with the test results for the small-scale PCHE and then used to design the medium-scale PCHE prototype.
