- W2065436574 abstract "이 시스템에서는 Fig. 1에서와 같이 고온가스덕트(Hot Gas Duct), 중간열교환기(Intermediate Heat Exchanger; IHX) 및 공정열교환기(Process Heat Exchanger) 등으로 구성된 중간루프가 반드시 필요한데 특히 IHX 는 원자로에서 생산된 초고온 열을 수소 생산 공장으로 전달하는 핵심 기기로서 약 900℃ 정도의 초고온하에서 작동하고 있다. 인쇄기판형 열교환기(Printed Circuit Heat Exchanger; PCHE)는 유체가 통과하는 미세한 유로를 화학적 etching 방법으로 형성하고, 유로들이 형성된 유로판Key Words: Printed Circuit Heat Exchanger(PCHE; 인쇄기판형 열교환기), High-Temperature Structural Analysis(고온 구조해석), Very High Temperature Reactor(VHTR; 초고온가스로), Intermediate Heat Exchanger(IHX; 중간열교환기) 초록: 초고온가스로의 중간열교환기는 원자로에서 생산된 950℃ 정도의 초고온 열을 수소생산 공장으로 전달하는 핵심 기기이다. 한국원자력연구원에서는 중간열교환기의 후보 형태로 고려되고 있는 인쇄기판형 열교환기의 실험실 수준 시제품을 제작하였다. 본 연구는 초고온헬륨루프 시험조건하에서 SUS316L 로 제작된 실험실 수준 인쇄기판형 열교환기 시제품의 고온구조건전성을 미리 평가하기 위한 작업의 일환으로 인쇄기판형 열교환기 실험실 수준 시제품에 대한 고온 구조해석 모델링, 거시적 열 해석 및 구조 해석을 수행하고 그 결과들을 정리한 것이다. Abstract: The Intermediate Heat Exchanger (IHX) of a Very High Temperature Reactor (VHTR) is a core component that transfers the high heat of 950℃ generated in the VHTR to a hydrogen production plant. The Korea Atomic Energy Research Institute manufactured a lab-scale prototype of a Printed Circuit Heat Exchanger (PCHE) as a candidate for an IHX. In this study, as a part of a high-temperature structural integrity evaluation of the lab-scale PCHE prototype made of SUS316L, we carried out high temperature structural analysis modeling and macroscopic thermal and elastic structural analysis for the lab-scale PCHE prototype under helium experimental loop (HELP) test conditions as a precedent study prior to the performance test in HELP." @default.
