In the long term and with internationally acclaimed results, we are researching materials to ensure nuclear safety, prolong the life of nuclear facilities, and develop new materials for non-nuclear use. We also participate in the development of nanotechnology applications for nuclear energetics and radioactive waste management.

Specialized workplaces:

  • A complex of hot and semi-hot cells for the realization of experiments and analyses on irradiated materials of nuclear power plant components. At present, the reconditioning of test bodies using the electron beam is carried out as part of the supplementary evidence programs of the VVER-440 and VVER-1000 reactor pressure vessels, which makes it possible to significantly improve the quality of information on the influence of irradiation on the mechanical properties of reactor steels
  • Accredited laboratories for testing the mechanical properties of irradiated materials.

Material properties research

  • Research and development of materials for operating nuclear reactors, low power reactors, research reactors and new generation reactors
  • Experiments in the framework of surveillance programs of nuclear power plants - testing of mechanical properties of irradiated materials, including determination of influence of interaction with the environment (eg autoclave tests)
  • Tests of mechanical properties of advanced materials for Gen IV reactors (eg ODS steel, Ni alloys)
  • Testing of environmental impact, irradiation, and loading of different types on the life of materials
  • Simulation of weld materials aging and evaluation of related changes in mechanical properties
  • Research on Fuel Cover Materials.

Use of nanomaterials for nuclear applications

In cooperation with other specialized institutions (Faculty of Nuclear and Physical Engineering, Czech Technical University in Prague and Institute of Inorganic Chemistry of the Academy of Sciences of the Czech Republic) we develop and test nanomaterials for the following applications:

  • The capture of radionuclides released into the environment by human activity
  • Decontamination of waste solutions
  • The provision of emergency response and mitigation
  • As fillers in filter systems for nuclear power plants, armed forces, and medical facilities

Testing and using nanomaterials based on:

  • Nanoparticulate metal oxides (Al2O3, TiO2, NiO, ZnO), double or ternary oxides
  • With a garnet or spinel structure
  • Nanoformygrafen and graphene oxide or their modified forms with Ag
  • Nanomaterials based on aluminosilicates substituted with Ag and Cu particles and the like
