Abstract
This article presents the first stage of work on the implementation of the project for the creation of an installation for testing fusion materials at WWR-K reactor using the vacuum extraction method. In particular, the data of calculations of the vacuum system of the installation for various geometries of the vacuum path are presented. The developed model made it possible to estimate the range and distribution of pressures along the length of the irradiation device and the vacuum system.
The obtained values of the pressure distribution showed that, in general, the physical ability to register the flow of tritium and helium into the system will be sufficient for the levels of production of tritium and helium in the samples under study above 10-11 mol/s.
