Calculation of In-core Fuel Management and Orthogonal Optimization for Xi'an Pulsed Reactor

Abstract

Abstract: An in-core fuel management code package HEX-ICFM is developed for Xi'an Pulsed Reactor.The orthogonal design model and the loading pattern optimization program HEX-ORTH are studied.The cell calculation is performed using WIMS-D/4.A two dimensional hexagonal geometry multigroup nodal theory code SIXTUS-2 is used for core diffusion calculation.The core physical parameters are calculated using HEX-ICFM for the first cycle of Xi'an Pulsed Reactor.With the fuel of end of cycle 3 and 30 fresh fuel rods the optimum loading patterns are calculated for the objective function max(K^BOC_eff)using HEX-ORTH.

Key words: Xi'an pulsed reactor, in-core fuel management, orthogonal design method, optimization
