岭澳核电站二期18个月换料燃料管理研究

Fuel Management Study on 18-Months Fuel Cycle for Ling’ao Phase-II Nuclear Power Station

对岭澳核电站二期从首循环开始向18个月换料过渡,并于第四循环达到平衡循环的燃料管理策略进行了研究,包括对燃料循环长度的计算、可燃毒物的使用、堆芯装载方式的布置、主要中子学参数计算等。从燃料管理的角度论证了岭澳核电站二期18个月换料的可行性,为最终的燃料管理方案的确定提供一定的理论依据。

A typical 18-months fuel cycle strategy is introduced in this paper.It deals with the transition towards 18-months reload from the first cycle and reaching equilibrium cycle through the minimum cycles at Ling’ao Phase-II Nuclear Power Station.Cycle length,gadolinium use,loading pattern,as well as main key safety parameters are given.The fulfillment of the study demonstrates the feasibility of launching 18-month reload at Ling’ao phase-II and offers theoretical basis for determining the final fuel management...
