The ASOF project, acronym of Advanced Separation for Optimal management of spent Fuel, targets the development of new, innovative processes for the separation (WP1), conversion (WP2) and conditioning (WP3) of spent fuel. The aim of the project is to initiate research within the Belgian national framework in view of a clear optimisation of the final disposal concepts for nuclear waste (WP4). The project is conceived and executed by the Belgian Nuclear Research Centre SCK•CEN within the framework of the Energy Transition Fund, founded by the Federal Public Service Economy in order to stimulate and support research and development on energy transition. This project deliverable D4.1 is part of WP4 of the ASOF project and aims to provide an overview early in the project of the quantities and general characteristics of the Belgian nuclear fuel, the Belgian radioactive waste classification system, the current disposal concepts proposed by ONDRAF/NIRAS for geological disposal, and the main drivers for the application of advanced separation. Based on the Belgian situation, efforts are made to identify possible preconditions for the separation and conditioning processes, if known. These preconditions include a proposal for a radiological and chemical inventory of a reference UOX and MOX fuel and argumentation for joint conditioning of heat-emitting Cs and Sr waste from a disposal perspective. Additional preconditions may follow from the requirements for the conditioning processing or its optimisation depending on the choice of immobilization matrix. These type of
