摘　　要：海南核电厂1、2号机组采用我国自主设计的CNP650反应堆,由于海南电网存在着明显的用电峰谷期,使得海南核电厂从年换料向长燃料循环过渡的关键在于循环长度差异巨大的长、短交替运行设计。面向上述目标,本文针对CNP650反应堆,完成了新燃料组件类型和富集度设计、新燃料组件数目及布置设计、独立过渡循环设计,得到了CNP650反应堆长、短交替运行的长燃料循环燃料管理策略,从1号机组第5循环开始,通过4个过渡循环,进入循环长度分别为517.3等效满功率天(EFPD)和464.0EFPD的交替运行平衡循环,各项参数满足长燃料循环燃料管理设计要求,有效地解决了海南核电厂长周期运行的特异性需求,可直接应用于海南核电厂长燃料循环运行。Unit 1 and unit 2 of Hainan Nuclear Power Plant adopt CNP650 reactor developed on self-reliance. Because of the obvious peak and valley period of the power consumption in Hainan power grid, the key to transition from annual refueling to long cycle is the great differences of the cycle length between the long and the short cycles. For these purposes, this paper completed the design of new fuel assembly types and enrichment, new fuel assembly number and layout, and the independent transition cycle, and then obtained the fuel management strategy of CNP650 rector. This strategy is composed of the alternative long and short equilibrium cycles, starting from the 5 th cycle, through 4 transition cycles, into the equilibrium cycle. The equilibrium cycle are composed of 2 cycles which length are 517.3 EFPD and 464.0 EFPD. All the parameters meet the design requirements of the long fuel cycle management. This fuel management strategy effectively solves the specific requirements of Hainan Nuclear Power Plant, and can be directly used for the operation of Hainan Nuclear Power Plant.
