Neutronic properties optimization of the IRT-T reactor core

TResearch results of IRT-T reactor core modernization ways are shown in this article. This work describes current characteristics of reactor core and experimental facilities. Some possible ways of altering the configuration of the core during modernization are presented. For every variant of layout length of cycle and non-uniformity factors for energy release in reactor core were calculated. Alternative layout of reactor core which allows creating additional experimental channel near the lower border of the reflector with the same characteristics of thermal and fast neutron flux as in HEC-4.
