摘　　要：使用KASKAD程序包,对田湾核电站从首循环开始使用TVS-2M组件展开研究,提出相应的燃料组件设计。以此为基础展开燃料管理研究,提出3个燃料管理方案(年换料方案和两个长周期换料方案)。对每个方案中堆芯的安全参数及其他重要参数进行分析,结果表明各种安全参数均满足设计要求。长周期的换料方案是从首循环就开始使用TVS-2M组件,并且只经过2个循环的过渡,寿期长度便达到了长周期的要求。长周期换料方案可提高电厂的年均能力因子,并在整个堆芯寿期内减少大修次数,因而每年节约30.8%的大修费用,因此电厂的经济效益得以提高。Using KASKAD program package, the author make a research about the Tianwan nuclear power plant loading TVS-2M fuel assembly from the first cycle, also design the TVS-2M fuel assembly and on this basis, study fuel management, obtaining three fuel management cases, including year fuel cycle case and two long fuel cycle cases. In each program, the important parameters of the reactor core are analyzed and all the safety parameters meet the design requirements. In long fuel cycle program, TVS-2M is using from the first cycle and after the transition of only two cycles, the length of cycle reached the requirement of long period. The increased average annual capacity factor of the plant and the decreased times of overhaul during the core＇s life which saving 30.8 percentage of the overhaul cost due to the long fuel cycle can largely improve the economic efficiency of the plant.
