Conceptual Design of Passive Residual Heat Removal System for 10 MW Molten Salt Reactor

College of Nuclear Science and Technology, Harbin Engineering University, Harbin, 150001, China

摘要: 以美国橡树岭国家实验室设计的10 MW熔盐实验堆(MSRE)作为研究对象,提出一种满足安全要求的非能动余热排出系统概念设计,给出系统回路的构成、主要设备及主要设计参数。同时对此系统的自然循环特性、排热能力等热工水力性能进行计算分析,结果表明,所设计的非能动系统可以满足反应堆余热排出要求,并具有相当的安全裕量,同时系统排热规律与排盐罐内的衰变热释放过程较为接近,确保熔盐温度平稳降低。

Abstract: A conceptual design of the passive residual heat removal system which can meet the safety requirement was developed for 10 MW Molten Salt Reactor Experiment（MSRE） designed by ORNL. The constitution, main components and main design parameters of the system were presented. Thermal-hydraulic behaviors such as natural circulation and heat removal ability were numerically analyzed. The results show that, the system can meet the design requirements of heat removal and has enough safety margin. Furthermore, the heat removal rate of the system is approximate to the decay heat generation rate, making the temperature of the molten salt decrease steadily.
