ABSTRACT

The irradiation tests in the core of the IR-8 reactor (RRC “Kurchatov Institute”) are planned for checking and confirmation of serviceability of a new rod type fuel element intended for using in the research reactors. The experimental fuel assembly (EFA) design has been developed. It allows to test a fuel element bundle under the conditions close to those which will take place during operation of the rod type fuel elements in the full-scale IRT-MR type FA. The neutron-physical, thermal hydraulic and stress-strain calculations substantiating the operation safety and representativeness of EFA tests are presented in the report.
