Abstract
This article presents one of the stages to create a facility for long-term testing of fusion materials at the WWR-K reactor. Particularly, data are presented on thermophysical calculations of an irradiating ampoule made of stainless steel
containing various materials of fusion breeders: lithium ceramics, lead-lithium eutectic.
The 3-dimensional axisymmetric model was used for calculations, according to which all elements are on the same axis. To simulate heat and mass transfer, we used the multiphysical module Nonisothermal Flow, which integrates the Heat Transfer in Fluids and Laminar Flow submodules for calculating the heat transfer in the ampoule metal and in the air flow in contact with the ampoule surface, and for calculating the velocity and pressure distribution in the flow, respectively. The dynamics of heating and the distribution of temperature fields in the ampoule were evaluated on the basis of which conclusions were made about parameters of the irradiation experiment.
