이차피동냉각시스템의 열교환기 설계를 위한 응축열전달 상관식 연구

국문 초록 (Abstract)

최근 원자로 시스템에서 응축열교환기를 이용한 피동안전냉각 개념이 활발히 연구되고 있다. 이차피동냉각시스템의 수직형 응축열교환기 설계를 위하여, 열적 크기 산정 프로그램(TSCON)을 구현하고 검증하였다. TSCON 검증을 위해 이차피동냉각시스템 응축열교환기 실험에서 수집된 1,157 개의 순수증기 응축열전달 실험데이터를 현존하는 응축열전달 상관식들을 이용하여 비교 검증하였다. 그 결과 2009년 Shah 에 의해 출판된 응축열전달 상관식이 수집된 실험데이터를 34.8% 오차로 예측하는 것으로 계산 되었으며, TSCON 의 응축열전달 상관식으로서 적합한 것으로 나타났다.

Recently, condensation heat exchangers have been studied for applications to the passive cooling systems of nuclear plants. To design vertical-type condensation heat exchangers in secondary passive cooling systems, TSCON(Thermal Sizing of CONdenser), a thermal sizing program for a condensation heat exchanger, was developed at KAERI(Korea Atomic Energy Research Institute). In this study, the existing condensation heat transfer correlation of TSCON was evaluated using 1,157 collected experimental data points from the heat exchanger of a secondary passive cooling system for the case of pure steam condensation. The investigation showed that the Shah correlation, published in 2009, provided the most satisfactory results for the heat transfer coefficient with a mean absolute error of 34.8%. It is suggested that the Shah correlation is appropriate for designing a condensation heat exchanger in TSCON.
