소듐냉각고속로용 인쇄기판형 증기발생기의 열성능 및 소듐-물 반응 압력전파에 대한 수치적 연구

다국어 초록 (Multilingual Abstract)

The Printed Circuit Heat Exchanger is expected to dramatically improve the safety and economics of the Sodium-Cooled Fast Reactor (SFR) when it used as the steam generator. In this study, the thermal performance of the Printed Circuit Steam Generator (PCSG) and the pressure propagation by the Sodium-Water Reaction is numerically analyzed. Based on the stress calculation for the wall of flow channel and the 1D heat transfer analysis, the cross-section and length of PCSG is determined. The STAR-CCM+ is used to evaluate the thermal performance of designed PCSG. Although the flow maldistribution (∼19%) exists in the feed water channels, the analyzed thermal power is around 26 MW close the target thermal power. The SWR pressure propagation is analyzed by the SWAAM-II Code. There is no pressure propagation from the PCSG to the Intermediate Heat Transport System of the SFR due to the volume difference between the flow channel and header.
