Abstract

Abstract

KYLIN-II program uses a projected predictor-corrector method for the critical burnup calculation. In this paper, the effect of different depletion timestep on the calculated k_inf was analyzed for PWRs with pure UO₂ fuel assemble, boron UO₂ fuel assemble and gad-loaded UO₂ fuel assemble, using KYLIN-II program. By comparing with the results, the proper depletion timestep is provided for different types of fuel assembles, to have accurate solution.
