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。
In this paper, the main contents and experimental results of the research and experimental research on advanced PWR iron-water reflector assembly are described in detail, and the calculation program is verified and analyzed with the experimental results. Experimental results and theoretical analysis have been iron-water reflector layer assembly can effectively reduce the fast neutron flux rate on the inner surface of the pressure vessel, can delay pressure vessel irradiation damage, extend the service life, and iron-water reflector layer component pairs The core has a positive reactivity effect of this important conclusion.
