Resumo
This article is devoted to the computational validation of algorithms for determining the reactivity on the basis of the spectral projection method and the method of reconstruction of the neutron fields. The determination of the efficacy of control organs on the RBMK critical stand on the basis of the indications of several intra-zone chambers is examined. A series of numerical experiments on the release of control rods and modeling of neutron-detector currents is conducted. The computed currents and a perturbed neutronphysical model based on the proposed algorithms are used to reconstruct the neutron fields and calculate the subcriticality of the RBMK stand. It is shown that the efficacy of control rods determined in this manner agrees with the exact values.
