Abstract:
In order to solve the depletion problem of Gas-Cooled Fast Reactor(GFR) quickly and accurately,a deterministic code system is developed.Based on the general compution framework of depletion process,some codes for data conversion,cross section regulation,depletion interpolation and automatic control,are programmed and used to couple the transport code WIMS and diffusion code CITATION.The simulation of the depletion process of one GFR model shows that the deterministic code system is feasible,and it is capable to analyze the neutronics characteristics during the depletion process of GFR.
