Precision Neutron-Physical Experiments at the National Research Center Kurchatov Institute

Resumo

Precision (benchmark) experiments on uranium systems with different moderators performed at the National Research Center Kurchatov Institute in a wide range of enrichment, ratios between the nuclear concentration of the moderator and uranium, as well as temperature are reviewed. The requirements of the arrangement of the experiments and participation of Russian specialists in international projects for the evaluation of the benchmark-experiments in terms of the critical nuclear safety (ICSBEP) and evaluated reactor-physical benchmark-experiments (IRPhEP) (NEA OECD) are discussed. The evolution of the experimental base required for performing such experiments and its current status are briefl y discussed.
