两种压水堆核燃料循环模式的经济性分析研究

Two Kinds of Pressurized Water Reactor Nuclear Fuel Cycle Models Analysis of the Economy

摘要: 本文用过对两种压水堆核燃料循环模式建立经济分析的数学模型，结合我国核能发展战略，对比分析了两种核燃料循环的费用及成本，并对敏感参数进行了分析，得出结论：一次性通过燃料循环比进行后处理的燃料循环模式大约节约14.7%的资金，当维持乏燃料后处理价格在800 $/kg时，天然铀价格上涨至160 $/kgU，对乏燃料进行后处理更加经济，而且进行乏燃料后处理后为核废物的贮存节约了大量空间。

Abstract: This paper has established the mathematical modeling of nuclear fuel cycle model in two different pressur- ized water reactors. Comparative and sensitive analysis of costs of two nuclear fuel cycle models was conducted. With the combination of China’s nuclear power development strategy, the result showed that disposal fuel circulation model can save about 14.7% of costs in the post-treatment cycle model. However, it’s more economic for the post-treatment cycle model when the price of natural uranium rises up to 160 $/kg U. Also, it greatly saves the storage room for the nuclear waste.
