从不同燃料循环模式分析快堆燃料循环的经济性

Economic Analysis of Fast Reactor Fuel Cycle with Different Modes

由于技术经济数据获取的局限及缺乏有效验证,国内对有关快堆燃料循环的经济性缺乏深入研究。文章介绍了美国麻省理工学院(MIT)对包括快堆燃料循环在内的3种不同燃料循环模式下,平准化发电成本的测算结果和对比分析。运用MIT评价方法及提供的假设参数,就比投资,贴现率及铀价格变化对三种燃料循环模式的平准化发电成本的影响,进行了敏感性分析。最后,针对我国快堆燃料循环经济性研究提出了建议。

Because of limitations on the access to technical and economic data and the lack of effective verification, the lack of in-depth study on the economy of fast reactor fuel cycle in China. This paper introduces the analysis and calculation results of the levelized cost of electricity(LCOE)under three different fuel cycle modes including fast reactor fuel cycle carried out by Massachusetts Institute of Technology(MIT). The author used the evaluation method and hypothesis parameters provided by the MIT to carry out the sensitivity analysis for the impact of the overnight cost, the discount rate and changes of uranium price on the LCOE under three fuel cycle modes. Finally, some suggestions are proposed on the study of economy in China's fast reactor fuel cycle.
