Improving Radioactive Waste Management, Spent Fuel and Decommissioning Arrangements endeavours to improve the safety of the management of spent fuel and radioactive waste and decommissioning in the European citizen interest. It strives to identify elements, approaches and measures for a continuous improvement of the safe management of spent fuel and radioactive waste and of the decommissioning, to strengthen cooperation, to promote joint effort in building and maintaining competence and knowledge, particularly in order to answer the challenges regarding qualified staff and knowledge resources during and beyond the decommissioning phase and to monitor the enhancement of the financing of the decommissioning of the nuclear installations and the safe management of spent fuel and radioactive waste. It provides guidance to facilitate the implementation of EU legislation in the field of nuclear waste safety. It assists ENSREG in any issue in this field.
