混合堆共生系统核燃料循环模式情景研究

为计算混合堆在未来燃料循环过程中起到的作用,进行了混合堆共生系统物料平衡计算。根据我国核电发展现状和中长期发展规划及中长期(2030年、2050年)发展战略研究,并充分考虑了我国经济发展速度、人口数量和人均用电量,计算得到了2100年之前,我国核电机组装机容量。假定不同堆型搭配的混合堆共生系统核燃料循环的4种情景并建立对应的物料平衡模型进行计算。计算结果表明,压水堆、混合堆和快堆共生模式能最大限度的减少天然铀的需求和节约乏燃料处置费用。

Nuclear fuel cycle scenarios on fusion-fission hybrid reactor symbiotic systems

In order to evaluate the importance of fusion-fission hybrid reactor (FFHR) in the future fuel cycle, FFHR symbiotic systems mass balance calculations were carried out. Nuclear energy development scenarios were studied according to nuclear power development status and long-term development planning, and long-term(2030, 2050) development strategy research in China. The growth rate of Chinas economy, population and per capita electricity consumption were taken into account. Chinas installed capacity of nuclear power plants before 2100 was calculated. Four scenarios were assumed as different types of fuel cycle and material balance models were established accordingly. The results show that PWR, FR and FFHR symbiotic model could minimize the demand for natural uranium and save spent fuel disposal cost.
