Abstract

This paper covers some specific features of the optimization problem with integer-valued and continuously changing parameters that has been formulated for a fast reactor operating under the steady-state regime of the uniform partial refueling. Effective algorithms for calculating the physical characteristics and an iterative procedure of constructing optimum values of parameters are proposed. The paper considers the solution of a problem on minimization of the loss of energy generation in a reactor of the BREST-800 type that occurs because average fuel burnup in fuel assemblies being removed does not achieve its maximum permissible level. For several core arrangements, the comparison with nonoptimum solutions is given and the role of various factors contributing to an increase in average fuel burnup is evaluated.
