Abstract
An improved method of an optimal fuel-reloading strategy is described. The method applies linear programming to a reactor model with a certain number of zones, with weighting functions, which contribute to the fuel consumption and the reactivity of the system. The method is applied to a BREST type reactor. It is shown that the equilibrium state of fuel reloadings with five-year irradiation in each zone and a one-year microrun can be reached in a 20-yr transitional regime with complete reloading of the inner zone after one year of operation and the first reloading of the outer zone after a 6-yr maximum admissable irradiation limit.
