The modular device for carrying out oxidation researches of carbonic materials samples in the air and wet environment in the temperature range 400 … 1200 °C under electronic irradiation is prepared (see Fig. 2). The modular device consists of an irradiation chamber and the device for preparation and submission of the air and wet compound which are placed on a final part of the ELIAS electrons accelerator (see Fig. 3).

On the basis of the prepared equipment the experimental section for study of influence of the air and wet environment and irradiation by the charged particles (electrons) of carbonic materials. It will allow to conduct unique researches of carbonic materials behavior of nuclear power systems generation IV in hypothetical conditions of accidents with a depressurization of the core.

Standards of the enterprise are developed:
