INVESTIGATION OF THERMOHYDRAULIC AND NEUTRON -PHYSICAL CHARACTERISTICS OF PERSPECTIVE FUEL ASSEMBLY FOR LOW-POWER REACTOR FACILITY
The paper presents the results of a numerical study of hydrodynamics and a temperature field in the model of the fuel assembly for the KLT-40S reactor installation in the transition to a fuel consisting of spherical microfuels. The optimal design of a model of a f uel assembly with microfuels for a reactor installation KLT-40S is proposed, from the position of hydrodynamics and heat transfer. The fuel assembly by external dimensions completely corresponds to the traditional assembly with rod fuel elements. The optim al parameters of the perforation of the covers that retain the pebble bed of microfuels are determined. The results of the evaluation of neutron-physical characteristics are presented. The working capacity of the KLT-40S reactor installation is shown when using fuel from microfuel elements.
