В данной статье представлен один из этапов работ по реализации проекта создания установки для длительных испытаний материалов ТЯР на реакторе ВВР-К. В частности, приведены данные теплофизических расчетов облучательной ампулы из нержавеющей стали, содержащей различные материалы бридеров ТЯР: литиевую керамику и свинцово-литиевую эвтектику.

Для расчетов была использована 3-х мерная осесимметричная модель, по которой все элементы находятся на одной оси.

Для моделирования тепломассопереноса использовался мультифизический модуль Nonisotermal Flow, интегрирующий в себе субмодули Heat Transfer in Fluids и Laminar Flow для расчета теплопереноса в металле ампулы и в потоке воздуха, контактирующего с поверхностью ампулы, и для расчета распределения скоростей и давления в потоке, соответственно.

Была оценена динамика нагрева и распределение температурных полей по ампуле на основе чего сделаны выводы о параметрах облучательного эксперимента.

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 steelcontaining 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.
