5-17 Neutronic Research on Gas-cooled Travelling Wave Fast Reactor

摘要

In order to improve the utilization of uranium resources and alleviate nuclear waste disposal pressure, a schemeof 500MWth Gas-cooled Travelling Wave Fast Reactor (GTWFR) has been designed. The MCNPX and CINDER90code have been used to calculate and analysis the neutronic parameters in GTWFR scheme within 25 burning years.The results show that the GTWFR can keep self-sustaining within 20 years without refueling using once-throughfuel cycle. The system has promising neutronics performance, as it has flat power distribution, deep burnup, andcan remain stable in ultra-long period in consequence of the transmutation of breeding wave.
