非能动专设安全设施应急余热排出试验研究

在海水淡化堆综合模拟试验装置上，开展了非能动专设安全设施应急余热排出模拟试验研究，获得了系统参数对非能动余热排出特性的影响规律。利用RELAP5/MOD3.2程序对蓄压水池不同初始水位下自然循环的建立和余热导出的过程进行了计算。结果表明，RELAP5/MOD3.2程序能较好地模拟海水淡化堆非能动专设安全设施的非能动余热导出过程，计算结果与试验结果符合较好。

Test Research on Special Passive Safety Facility for Emergency Residual Heat Removal

Simulation experiments were carried out on the simulation test facility for nuclear seawater desalination reactor, and the performance of the passive residual heat removal from the core was presented. Numerical model was built by RELAP5/MOD3.2 code to simulate the influence of natural circulation establishment and the residual heat removal with different initial water levels in accumulator tank. It is shown that the RELAP5/MOD3.2 code can well simulate the passive residual heat removal process of the passive safety facility of the seawater desalination reactor, and the calculation results of the code are well accordant with the experimental results.
