The purpose of the work is the development of scientific and technical and economic recommendations for optimal management of SNF aging. Research methods are an analysis of the features of the course of neutron-physical, thermal and chemical processes in the elements of SNF equipment, physical and mathematical modeling of the course of these processes. Research results - Management of spent nuclear fuel (SNF) is an urgent scientific and technical task, taking into account the important role of the nuclear power industry of Ukraine in ensuring its energy independence. The interim report for stage No. 1 contains: • Results of a review of technical literature on the topic of managing the aging of structural elements of ventilated concrete containers for the storage of SNF; • Main technical characteristics of the ZNPP SSNF, including in terms of monitoring the technical condition of concrete and metal surfaces of structural elements of ventilated concrete spent fuel storage containers;. • Radiation damage assessment was carried out on the Serpent model of the HI-STORM 190 storage system; • A methodology for substantiating new types of concrete to prevent material aging and increase its service life was proposed. When performing the research, national scientific and technical documents on nuclear and radiation safety, on securing NPP operation, the existing NPP operation infrastructure and spent fuel management, and global trends in spent fuel management were taken into account. Recommendations for using the results of the work - the results of the research will be implemented when substantiating the spent fuel management program. Scope of application - the nuclear energy industry of Ukraine. Product Description popup.authors Horanchuk Vadym V. Hulik Volodymyr I. Dorman Oleksandr Yu. Kuchmahra Oleksandr A. Romanenko Iryna M.
