Abstract
This work is devoted to the development of a methodology for conducting reactor experiments to study the interaction of hydrogen isotopes with lithium CPS by the dynamic sorption method. As a result of the work the design of an experimental irradiation device for conducting reactor experiments was developed. Neutron-physical and thermophysical calculations were performed to justify this design for use in reactor experiments. A technique was developed for conducting experiments with a sample of lithium CPS as a result of which the methodological conditions of the tests were determined: sample temperature; levels of deuterium flux supplied to the experimental cell; sample size; sample pretreatment conditions; system pump out mode, sample temperature adjustment mode, mass spectrometric measurements of the gas composition above the sample. Methodical experiments were carried out to determine the temperature dependence of the gas composition change in the chamber with a lithium CPS when various deuterium flows were applied. Thermal desorption experiments with a sample of lithium CPS were carried out.
