Conceptual basis for organizing the decommissioning a nuclear power plant based on a reactor unit

Small nuclear power plants are the most promising and effective solution for the economic and social development of hard-to-reach regions both in Russia and abroad. The SNPP is one of the main directions of nuclear power development in Russia. Practice shows that the operating organization is usually not ready for the decommissioning process. It is necessary to prepare for the decommissioning of a nuclear power facility in advance. In large nuclear power engineering, nine power units of nuclear power plants are already waiting to be decommissioned; practically no real work has been carried out since 1977. The lack of funds, technologies, radioactive substance storage facilities, spent nuclear fuel processing technologies and specialists in the field of decommissioning impose a restraining imprint on the decommissioning process. It necessitates preparing for the final stage of the existence of nuclear power facilities. The paper presents the concept of decommissioning of small nuclear power plants with RITM-200N reactors developed by the authors.
