基于轻水冷却的压力管式混合堆,采用压水堆卸载的乏燃料以及天然铀氧化物陶瓷燃料,建立混合堆包层的换料方案,详细计算了包层中子学性能随燃耗的变化情况,计算结果表明,包层在维持3000 MW热功率输出的同时,可以保证氚自持(氚增殖比TBR>1.20),而每5 a仅需向包层添加80 t左右的重金属燃料。基于建立的平衡循环计算了包层采用不同燃料时的单位发电燃料成本。结果表明,采用乏燃料和天然铀时的单位发电燃料成本分别为1.82×10-3、1.35×10-3$/(k W·h)。
Based on the light water cooled pressure tube hybrid reactor, the spent fuel unloaded by pressurized water reactor and the natural uranium oxide ceramic fuel were used to establish the refueling scheme of mixed reactor cladding. The results show that the cladding can guarantee the tritium self-sustainment (tritium multiplication ratio TBR> 1.20) while maintaining 3000 MW thermal power output, and only need to add about 80 t heavy metal fuel to the cladding every 5 years. Based on the established equilibrium cycle, the unit power generation fuel cost for different cladding layers was calculated. The results show that the unit fuel cost of spent fuel and natural uranium are 1.82 × 10-3 and 1.35 × 10-3 $ / (kw · h), respectively.
