To solve the current problem of the depletion of the free volume of existing high-level waste storage facilities and the operation of the high-level waste management infrastructure at the Chernobyl NPP and the object “Ukryttya”, it is planned to introduce high-level waste storage facilities at the Chernobyl industrial site. The storage facility is intended for reception and long-term storage of high-level waste that will be generated when the Chernobyl NPP power units are decommissioned; the object “Ukryttya” is converted into an environmentally safe system and for nuclear fuel reprocessing products of Ukrainian NPPs. The storage location is planned in the turbine hall and has an economic justification - the hall is already equipped with the necessary engineering networks, hoisting mechanisms, transport entrances and security protection system. In order to obtain the necessary initial data for the design of the storage facility, the specialists of the Institute for Safety Problems of Nuclear Power Plants of the National Academy of Sciences of Ukraine carried out complex studies of radiation conditions. The dose rate of gamma radiation, the density of surface contamination, the concentration of aerosols in the air, and the energy characteristics of gamma radiation and the angular distribution of gamma-radiation intensities were measured.
Keywords: radiation conditions, turbine hall, Chernobyl NPP, storage of high-level waste.
