- W4387150323 abstract "In this paper, a simplified model for light water moderated reactor refueling optimization is presented. Specifically, a calculation model is proposed that significantly reduces the processing time involved in the nuclear reactor optimization calculations. Such calculations aim to minimize the number of fresh fuel assemblies required by a reactor over a finite planning horizon subject to nuclear power generation, safety requirements and reactor design specifications. The optimal refueling policies are a very important subject for the economics and safety of nuclear reactor operation. The prime challenge in the determination of fuel assembly patterns is the possibility of many pattern combinations within the reactor core. Moreover, given that this is a discrete and nonlinear problem, it poses difficulties in the use of conventional optimization techniques. Usually, an artificial intelligence algorithm is adopted to optimize the fuel pattern of a nuclear reactor, but a higher computational cost is needed to achieve high accuracy. Thus, in this work, we provide some simplifications in the neutronic calculations usually used to determine the nuclear power density, linear power density, total peaking factor, cycle length, etc, that reduces the processing time of the computer codes used to solve the neutron diffusion equation with very reasonable accuracy." @default.
