Measurement of VVÉR Control Rod Efficiency

Atomic Energy Aims and scope

Abstract

The reasons for the large discrepancies between the computed and experimentally measured values of the efficiency of control rods observed during startup experiments on a VVÉR reactor are discussed. The spatial distribution of the neutron flux has the greatest effect. A method for eliminating the influence of spatial effects on the measurements of control rod efficiency is proposed. The possibilities of the proposed method are illustrated for examples of the analysis of experiments performed on power-generating units with VVÉR-440 and -1000 reactors.
