Abstract:

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.
