| 摘 要： | 田湾核电厂1、2号机组计划自2014年开始向长周期燃料循环过渡,在AFA型燃料组件组成的堆芯中逐步装入TVS-2M新型燃料组件,经过3个燃料循环的过渡,堆芯将全部装载TVS-2M型燃料组件,以实现长周期燃料循环。燃料组件结构的改变使原堆芯热工水力分析不再适用。本文以长周期燃料循环过渡时期的5种典型堆芯组成情况为例,介绍了VVER机组稳态热工水力分析的程序和方法,对混合堆芯的稳态热工水力特性进行了重新分析。结果表明,混合堆芯稳态设计仍满足热工水力设计准则。

| Abstract: | Tianwan NPP Units 1 and 2 plans to transit to long fuel cycle from the year of 2014.The new type fuel assembly ＂TVS-2M＂will be introduced into the reactor core composed by AFA assemblies.After three fuel cycles,the reactor core will be loaded by all TVS-2M fuel assemblies and realize long fuel cycle. The thermal-hydraulic analysis should be performed again duing to the change of fuel assembly structure.This paper presents the thermal-hydraulic analysis procedure and method for the steady-state of VVER reactors, and re-analyzes the thermal-hydraulic characteristic of the mixed core,which include five types＇ core loading during transition.It turned out that the mixed core steady-state design is still fitted to the requirements for thermal-hydraulic design. |
