AC—600堆芯设计

Core Design for AC-600

本文叙述了 AC-600的堆芯核设计、热工水力和屏蔽设计.为了改善燃料利用和提高反应堆的安全性,在堆芯设计中,采用了低功率密度堆芯、较大的负反应性温度系数、机械谱移控制、钆可燃毒物、灰棒及不锈钢反射层等先进技术。

This paper gives an outline of the conception design and discussion forAC-600.Main contents contain nuclear core design,thermal hydraulics andshielding design.In odor to improve fuel utilization and to increase reactorsafety,the advanced technology,such as the lower power density core,thelarger negative temperature coefficient of reactivity,the mechanical spectralshift control,Gd burnable poison,the gray rod and stainless steel reflector,are used in the core design.
