Abstract:

In order to improve the utilization of uranium resources and alleviate nuclear waste disposal pressure, a scheme of 500MWth Gas-cooled Breeding Fast Reactor (GBFR) has been designed. The MCNPX and CINDER90 code have been used to calculate and analysis the neutronic parameters in GBFR scheme within 25 burning years. The results show that the GBFR can keep self-sustaining within 20 years without refueling using once-through fuel cycle. The system has promising neutronics performance, as it has flat power distribution, deep burnup, higher conversion ratio, and can remain stable in ultra-long period in consequence of the breeding effect.
