三代核电厂控制棒控制策略浅析

本文阐述了三代核电厂反应性控制模式,包括控制棒组和停堆棒组;反应堆功率控制策略,包括自动调节反应堆功率和自动控制功率分布;基于当前棒位和功率计算而来的控制棒插入限值;为克服灰棒非均匀消耗和燃耗屏蔽而引入了控制棒交换逻辑四个方面。对控制棒控制策略进行深入剖析,突出了三代核电厂控制棒控制的特点及优势。

This paper analyzes the third generation nuclear power plant control strategy of control rod in four sides, including the mode of reactivity control, which includes Control Bank and Shutdown Bank, reactor power control strategy, which includes automatic reactor power and power distribution control, Control rod insertion limits, we calculate it basing on current bank position and hot power, control rod exchange logic for defending no uniform expending of grey rod and burn up shield, explaining the feature and dominance of control rod controlling.
