FHR在全厂断电事故下对RVACS散热能力的要求
氟盐冷却高温堆（Fluoride salt-cooled High-temperature Reactor,FHR）是一种采用包覆颗粒燃料、高温熔融氟盐冷却剂的先进反应堆。部分FHR概念采用了反应堆容器辅助冷却系统（Reactor Vessel Auxiliary Cooling System,RVACS）导出事故下的堆芯余热。RVACS通过导热、对流换热、辐射换热等非能动过程,在事故发生时将堆芯余热排出至大气中。本文采用中国科学院上海应用物理研究所设计的10 MW FHR作为基准,利用RELAP5-MS程序,对其在全厂断电事故下的瞬态过程进行了模拟,验证了RVACS的余热导出能力。本文进一步...

| Abstract_FL | Background: Reactor vessel auxiliary cooling system (RVACS) is a passive residual heat removal system applied to thorium molten salt reactor-solid fuel (TMSR-SF1). There are difficulties to use it to high-power reactor with its multifunction reactor vessel. To maximize vessel integrity, vessel should be minimized. Purpose: This study aims to verify the heat-discharge capability of the RVACS under station blackout accident (SBO).Methods: With a 10-MW fluoride salt-cooled high-temperature reactor (FHR) designed by Shanghai Institute of Applied Physics of Chinese Academy of Sciences as the baseline design, the RELAP5-MS code was adopted to simulate the transients during a SBO.Results: A scope of RVACS power for heat dissipation of FHR under SBO is given by this study. Conclusion: The heat-discharge capability of the RVACS was verified. |
