摘要

本研究对SNCLFR-100自然循环铅冷快堆堆芯进行了热水力分析。用基于多孔介质方法的代码TWOPORFLOW进行稳态和瞬态分析。在稳态分析中,采用装配方式分析了组件的质量流分布和温度分布。同时,从引脚的角度分析了最高温组件,并对其安全性能进行了研究。在暂态分析中,采用单向耦合方法对典型的设计扩展条件下无保护过功率暂态进行了仿真。

Thermal-Hydraulic Safety Analysis of Natural Circulation Lead-Cooled Fast Reactor SNCLFR-100 Core Based on Porous Medium Approach
In this study, a thermal-hydraulic analysis is carried out for the core of natural circulation lead-cooled fast reactor SNCLFR-100. Steady-state and transient analysis are performed with porous medium approach-based code TWOPORFLOW. In the steady-state analysis, mass flow distribution and temperature distributions of the assemblies are analyzed in assembly-wise mode. At the same time, the hottest assembly is analyzed in pin level and the safety performance is investigated. In the transient analysis, a typical Design Extension Conditions unprotected over-power transient is simulated with one-way coupling method.
