超临界水实验回路热工水力分析
Thermal-hydraulic Analysis of SWAMUP Test Facility
摘要
Abstract
T rans‐critical transients ,i .e .the pressure in the reactor system undergoing a rapid decrease from the supercritical pressure to the subcritical condition ,are of crucial importance for the LOCA analysis of supercritical water cooled reactor (SCWR) .To obtain more knowledge about this process ,the supercritical water multipurpose loop (SWAMUP) test facility in Shanghai Jiao Tong University (SJTU) will be applied to provide test data for the process .Some pre‐test calculations are necessary to show the feasibility of the experiment .In this study ,the trans‐critical transient analysis was per‐formed for the SWAMUP test facility with the system code ATHLET‐SC which was modified in SJTU .The system behaviors including system pressure ,coolant mass flow , and wall temperature of heating rod during the depressurization were presented .The effects of some important parameters such as depressurization rate ,heating power of heating rod on the system characteristics were also investigated .The results indicate that the revised system code ATHLET‐SC is capable of simulating thermal‐hydraulic behaviors during the trans‐critical transient .According to the results ,the wall tempera‐ture of heating rod during the transient is kept below the design limit .However ,the pressure difference between the heat exchanger inside and outside after depressurization could reach 6 M Pa ,w hich should be considered in the test .关键词
