Data on a shielded-enclosure block, which is part of the scientific-research complex at the Institute of Reactor Materials, are presented. The equipment for the primary post-reactor studies and methods of flaw detection in objects are described. Articles are cut into blanks and samples on in-box remote-controlled machines. The equipment and methods for determining the physical and mechanical properties...
The aim of this work was to investigate by means of secondary-ion mass spectrometry the isotopic composition of the matrix and the erbium consumable absorber in RBMK fuel samples in the initial state (enrichment from 2.4 to 2.8% in terms of 235U) and the state after irradiation in the IVV-2M reactor (to maximum burnup 34.4 MW·days/kg). It is found that burnup growth is accompanied by reduction of...
