秦山和大亚湾核电厂堆芯燃料管理策略改进的初步探讨

Preliminary Study on Improving InCoreFuel Management Strategy ofGNPS and QNP

对我国大亚湾及秦山核电厂的堆芯燃料管理策略的改进进行了初步探讨。对从传统三批年换料改进为四批年换料和延长循环长度（１４～１８个月）的可能性，以及可能取得的平均卸料燃耗增益进行了初步测算。研究表明，采用“增大循环燃耗”的先进燃料管理策略将带来重大的经济效益，是一项迫切需要研究的课题。

his paper presents a preliminary study on improving InCore fuel management strategy in Daya Bay Nuclear Power Plant(GNPS)and Qinshan Nuclear Power Plant(QNP).The feasibility of changing the reloading pattern from conventional 3 batches loading pattern(LP) to 4 LP and extending the cycle length to 14～18 months is evaluated.The possible benefit of average discharged burnup is calculated as well.The study shows that if the advanced fuel management strategy is employed,a remarkable efficiency in economics will be obtained.And it is an extremely urgent task to research advanced fuel management strategy for nuclear power plant in China.
