Tuzov Aleksandr Aleksandrovich - director

RIAR is Russia's largest research experimental complex of nuclear power, which provides services for irradiation and post-irradiation examination of materials, designs and demonstrates the innovative technology of fuel production for future nuclear reactors and advanced technologies of nuclear waste treatment. Besides, it develops and manufactures a large range of radionuclides and ionizing radiation sources for science, industry and medicine.

Unique multi-experimental base of RIAR enables to perform scientific and production activities in key development priorities of "Rosatom" State Corporation.

Key business lines:

  • research of materials and components of the reactor cores for different purposes in order to confirm the technical characteristics of the product and to determine the causes of leaks in fuel elements;
  • development of methods and devices, and organization of tests in research reactors, as well as pursuance of post-irradiation examination of staff and promising types of fuel, construction, inhibitory and absorbing materials and products;
  • development and production of experimental irradiation devices, re-fabricated fuel elements, fuel assemblies and other products of nuclear engineering;
  • performing material scientific experiments in order to prolong the lifetime of reactor installations;
