Information × Registration Number 0226U002732, (0123U101947) , R & D reports Title The guarantee of possibility to control the VVER-1000 reactor pressure vessel metal condition with surveillance specimens in modern conditions popup.stage_title Розробка методики підготовки джерел для розрахунки переносу нейтронів в складному за геометричними і матеріальними параметрами середовищі ядерного реактора, верифікація і валідація методики Head Bukanov Volodymyr M., Кандидат фізико-математичних наук Registration Date 05-03-2026 Organization Institute of Nuclear Research of the National Academy of Sciences of Ukraine popup.description1 Development of the main approaches of the modernization program of regular single-row container assemblies with surveillance specimens of the VVER-1000 reactor pressure vessel metal, taking into account the transition of the Ukrainian NPPs to the use of Westinghouse fuel, which would ensure the advanced irradiation of the specimens relative to the inner surface of the reactor pressure vessel and equalization of the values of neutron fluences accumulated by the surveillance specimens during the entire exposure time, for the possibility of selecting representative groups of specimens for testing popup.description2 It is worked out, verified and validated the methodology of preparation of neutron source parameters based on detailed Monte-Carlo calculations that use the full scale model of reactor core. It is created the codes to make consistent modeling a fuel cycle and neutron transfer. Product Description popup.authors Ilkovych Viktor V Puhach Oleksandr M. Bukanov Vladimir Hrytsenko Oleksandr V.
