In accordance with the requirements of Article 26 of the Federal law "On the use of atomic energy", the subject of the safety review was the analysis of safety justification compliance with the Russian Federation legislation, rules and regulations in the field of atomic energy use, current level of scientific development, technology and production. While reviewing, compliance with the federal rules and regulations in the field of atomic energy use was evaluated, including:

  • defence-in-depth with physical barriers;
  • operational capability of all physical barriers (fuel matrix, fuel rod cladding, reactor coolant boundary, leak-tight enclosure, biological shielding);
  • operating limits and conditions, limits and conditions for safe operation;
  • chemical regimes of the operating media in systems and elements for the provision of physical barriers integrity;
  • approval of technical solutions on the basis of testing, research and prototypes operating experience;
  • deterministic and probabilistic safety assessment, and others.

Key results of the safety review were presented by Mr. Sergey Bogdan, SEC NRS Deputy Director.

Mr. N. Ponomarev-Stepnoy, member of the Russian Academy of Sciences, and Mr. P. Alekseev, PhD, Scientific Head of Kurchatov Centre for Advanced Atomic Energy of the National Research Center "Kurchatov Institute" made presentations as reviewers.
