摘　　要：目前国内核电经济分析聚焦于压水堆,而对快堆的经济性分析主要为方法分析,案例分析较少;国际上代表性权威机构和高校给出了经济评价方法,但他们侧重于成本侧分析,收益侧分析较少。本文在国内外核电经济性分析方法的基础上,综合考虑一体化快堆的技术特点,提出了适用于一体化快堆的经济性分析方法,建立了度电成本模型和财务评价模型,并进行了初步经济分析。计算结果表明,一体化快堆首堆度电成本为0.279元/(kW·h),内部收益率(IRR)为3.65%。在系列化学习效应的加持下,度电成本呈下降趋势,当一体化快堆在建设投资下降至2万元/kW时,其度电成本可与压水堆相比,项目的IRR可达到行业基准收益率。Integrated fast reactor is a nuclear energy system consisting of a metal fuel fast reactor,a fuel regeneration facility(including dry spent fuel reprocessing and metal fuel manufacturing),and a waste preparation facility.It has the characteristics of integrated design,high fuel efficiency and low nuclear waste output.The technical difference with current nuclear power is embodied in the fact that the integrated fast reactor is a complete closed-loop fuel cycle system.The integrated construction strategy of one site and one plant can shorten the off-reactor circulation time to one year,and only a small amount of depleted uranium can be processed into new fuel and then re-entered into the reactor,so as to realize the rapid circulation and multiple circulation of fuel in the plant.The initial charge of the IWR is the spent fuel discharged from the MOX fuel fast reactor,which is processed by the dry reprocessing facility in the IWR and then sent to the metal fuel production line in the plant to be processed into metal fuel and loaded into the reactor for combustion.The economy of the integrated fast reactor is one of the main aspects of project decision-making,after the spent fuel is discharged from the reactor,processed into new fuel in the metal fuel production line,and then loaded into the reactor for combustion to achieve on-site self-circulation.At present,the economic analysis of nuclear power in China focuses on pressurized water reactors,while the economic analysis of fast reactors is mainly methodological analysis,and there are few case studies.International representative authorities and universities have provided economic evaluation methods,focusing on the cost-side analysis and less on the benefit-side analysis.Based on the characteristics of the closed fuel cycle of the integrated fast reactor,the economic evaluation method of the integrated fast reactor was studied by drawing on the economic evaluation methods at home and abroad,the economic evaluation model of the integrated fast reactor was proposed,a
