Study on Application of Zirconium Diboride（ZrB₂） in CPR1000 Quarter-Core Fuel Management

China Nuclear Power Technology Research Institute, Shenzhen, Guangdong, 518026, China

摘要: 采用SCIENCE V2软件包,对CPR1000核电厂1/4换料燃料管理采用硼化锆可燃毒物和氧化钆可燃毒物的组件反应性,以及采用这2种可燃毒物堆芯的径向功率峰因子、循环长度、停堆裕量等参数进行计算分析。结果表明,在CPR1000核电厂1/4换料燃料管理中采用硼化锆可燃毒物是可行的,可获得更长的循环长度。

Abstract: Using the SCIENCE V2 code package,the assembly reactivity of ZrB₂ and gadolinium oxide,and the core peaking factor,cycle length and shutdown margin of the core loaded with these two different burnable poisons are analyzed for CPR1000 quarter core fuel management mode.The results show that it is feasible to load the fuel assemblies with ZrB₂ burnable poison in CPR1000 quarter-core fuel management mode,and a longer cycle length can be obtained.
