IAEA mission was held at Chornobyl Nuclear Power Plant, which addressed the issues of buildings and structures decommissioning, decommissioning methods, as well as processing of radioactively contaminated concrete and waste generated, including radioactive ones.
Although the final state of Chornobyl NPP site does not include a large-scale dismantling of existing buildings and structures, a considerable amount of reinforced concrete waste will be formed during the Central Halls hipped roof reconstruction and the equipment dismantling. Another source of its generation will be Shelter object unstable structures dismantling. All this right now requires consideration of such waste decontamination and processing in order to minimize its volume. Existing at Chornobyl NPP decontamination system today is not intended for large-scale decontamination, does not allow to decontaminate firmly fixed contamination and leads to formation of a large volume of secondary waste.
