Abstract
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.
