Review of Modeling Experience During Operation and Decommissioning of RBMK-1500 Reactors. II. Radioactive Waste Management

Part I (Remeikis et al., 2021) of the review analyzed research done on the modeling of the RBMK-1500 reactor and its practical applications during operation of Ignalina Nuclear Power Plant. In this second review article the survey of the research done on modeling for decommissioning of the RBMK-1500 reactor as well as some perspectives for the future investigations are presented. During the last few decades considerable modeling experience has been accumulated in the field of radioactive waste management for RBMK-1500 decommissioning: inventory calculations of nuclear fuel and activated reactor construction materials as well as characterization of operational and decommissioning waste applying the modeling supported scaling factor method, evaluation of spent nuclear fuel containers for dry storage, fuel pools and fuel transportation safety, radioactive waste behavior under geological disposal conditions and alternative vision of nuclear waste transmutation. Important findings and key methodologies are highlighted and the need of scientific input is discussed. Additionally, an outlook on further research concerning RBMK-1500 reactor studies is provided.
