先进压水堆堆内铁-水反射层组件研制及实验研究

Manufacture and Experiment of Steel-water Reflector Assembly of APWR

本文较详细地叙述了先进压水堆铁-水反射层组件研制及实验研究的主要内容和实验结果,并利用实验结果对计算程序进行了验证和分析。实验结果与理论分析皆得到了铁-水反射层组件能有效降低压力容器内表面的快中子注量率,可延缓压力容器辐照损伤,延长使用寿期,且铁-水反射层组件对堆芯具有正的反应性效应这一重要结论。

The article introduces the main item and experimental results of APWR core with steel-water reflector assembly. The results are used to validate and analyze calculation program. From the experimental results and theoretic analysis, it is concluded that steel-water reflector assembly can effectively reduce fast neutron flux density of the inner surface of Pressure Vessel, delay irradiation damage on Pressure Vessel, prolong operation time, and increase the positive reactivity of the core.
