Abstract

Abstract

Shanghai Institute of Applied Physics proposed a technical solution based on the Thorium-based Molten Salt Solid-state Test Reactor (TMSR-SF1) based on TRISO-coated spherical particulate fuel and liquid fluoride salt. One of the most important works is the design of passive residual heat removal system (PRHRS). Because of the incompatibility between molten salt and water and its high operating temperature, it is necessary to use air as the final heat sink to design PRHRS. In order to achieve the design objectives of system simplification, volume minimization and consideration of heat removal and insulation, starting with the model of heat transfer process from MSR core active zone to external air heat sink, this paper establishes the PRHRS optimization design model, obtains the optimization design scheme, and based on the improved RELAP5/MOD4.0 code (special improved code for TMSR-SF1) carries out the demonstration and evaluation of PRHRS capacity. Calculation and analysis show that the design of PRHRS capacity is reasonable, which can ensure the heat removal safety after the reactor SBO.
