[en] The two stages of decommissioning (rinsing/decontamination and dismantling) are assessed using a specific methodology which includes: selection of 25 standard cells, development of a standard dismantling scenario and definition of approximately 50 cleanup tasks to be performed for each of the 25 standard cells, performance of a detailed inventory of the main characteristics of the cells to be dismantled, grouping of the 3000 active cells of French reprocessing plants into 25 standard cell categories. This assessment also provides numerical data relating to the effluents, wastes, integrated doses and other factors involved
