摘　　要：氚是聚变堆的关键核燃料,国内现有产氚能力不满足聚变能工程应用的需求,利用商业核电站产氚,具有成本低和有利于军控核查等优点。本文针对国内商业核电站反应堆特点,开展了轻水堆产氚方案设计和初步安全评价研究,提出了产氚靶棒的概念方案和核电站堆芯首装料方案,评估了产氚靶棒装载对核电站堆芯反应性、功率分布和慢化剂温度系数的安全影响,探讨了利用国内现有轻水堆核电站进行产氚的可能。Tritium is the nuclear fuel of fusion reactor.The current capacity of tritium production cannot meet the requirement of fusion energy.The tritium production by commercial nuclear power plants has the advantages of low cost and beneficial to arms control verification.In this paper,the design of tritium production by light water reactor and the preliminary safety evaluation are carried out according to the characteristics of domestic commercial nuclear power plants.The scheme of the tritium-producing rod and the loading plan of the core are put forward.The safety impacts of the reactivity,the power distribution and the coolant temperature reactivity coefficient are evaluated.The possibility of tritium production by the current light water nuclear power plant in China is discussed.
