Experimental data of the prototype reactors radiation safety are needed for large-scale deployment of innovative power units at the present stage of nuclear industry. The article is devoted to the results description of radiolytic processes and radiation safety of the VK-50 reactor facility. VK-50 is the reactor with natural circulation of coolant.

The information was obtained by empirical research. Estimated studies of the reactors radiation safety are based on the results of pilot studies.

The article is devoted to the results description of radiation safety of the VK-50 reactor facility. VK-50 is the reactor with natural circulation of coolant. The article describes the features of the catalytic combustion systems in accidents. The feature of phase transfer radioactivity can limit the consequences of severe accidents on the boiling-water reactor.

The unprecedented method is developed for determining the radioactive situation in the emergency box. The technological scheme and the operating conditions prevent the emergencies with explosions in equipment and shut out the accident with outlet of radioactive substances into the environment. The feature of phase transfer radioactivity can limit the consequences of severe accidents with coolant leakage.

The obtained results can be applied to confirmation of safety and to enhancement BWR.
