摘　　要：简要论述了核能在我国能源发展战略中的地位及聚变-裂变混合堆在核能持续发展中的重要作用。对以不久将来即可实现的ITER聚变装置作驱动堆芯、天然铀水冷裂变系统作包层的混合堆做了细致的分析。这种混合堆型可以实现GWe级净电功率输出,年造钚1 656 kg,支持2.68个同功率压水堆电站对易裂变燃料的需要。初步的经济评估说明,混合堆电的成本是同功率压水堆电成本的1.67倍;而在不计燃料成本的情况下,混合堆与压水堆组合系统电的成本是同功率压水堆电成本的1.18倍。考虑到一般压水堆需消耗大量的天然铀,加上铀浓缩成本,混合堆与压水堆组合系统电的成本,与压水堆电的成本是可以相比拟的。The strategic position of the nuclear energy in the development of China energy resources and the important role of the fusion-fission hybrid reactors in the sustained development of nuclear energy resources are analyzed.The hybrid reactor with ITER fusion device as driving reactor core which could be realized in near future and water-cooled natural uranium fission system as blanked is discussed.With hybrid reactor the 1 GWe net electrical power output and yearly fissile fuel production 1 656 kg that could meet need of 2.68 PWR（pressurized water reactors）for fissile fuel could be attained.A rough economic estimation predict that capital cost of hybrid reactor is 1.67 times as large as capital cost of same power PWR without including the cost of nuclear fuel;the electrical cost of combined system of hybrid reactor and PWR is 1.18 times of electrical cost of same power PWR.Considering cost of fissile fuel that PWR consume,the electricity cost of combined system of hybrid reactor and PWR could be competitive with PWR electricity cost.
