压水堆核燃料循环情景模式初步研究

根据我国核电发展现状和中长期发展规划及中长期（2030、2050）发展战略研究，假设2050年前我国压水堆核电发展规模，基于压水堆乏燃料后处理，回收的钚做成MOX燃料放入压水堆中使用，MOX燃料只使用1次的循环模式，进行核能发展情景研究。基于压水堆可装载30%比例MOX燃料的已有研究结果，考虑我国主要的两种压水堆堆型M310和AP1000，进行压水堆核燃料循环分析。利用核能发展情景动态分析程序DESAE-2，给出了不同情景模式下天然铀需求量、乏燃料累计量等。结果表明：至2050年，B₁和B₂模式较A模式分别节省天然铀4.1万t和2.9万t。

Preliminary Study on PWR Nuclear Fuel Cycle Scenarios

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 PWR nuclear power capacity was assumed before 2050. The scenarios were based on the PWR spent fuel reprocessing, making MOX fuel with recovery plutonium, and then using MOX fuel in PWR. MOX fuel was used only once in these fuel cycle scenarios. Preliminary PWR nuclear fuel cycle scenarios were studied according to PWR with 30% MOX loading and considering two main PWR reactor types M310 and AP1000. DESAE-2, which was a code with the interactive model for quantitative assessment of nuclear energy system key indicators, was used to calculate natural uranium demand and accumulated spent fuel at different nuclear energy development scenarios. The results show that the natural uranium demand can be saved 41 000 t and 29 000 t with B₁ and B₂ modes compared to the A mode by 2050, respectively.
