France – Engineering support services – Appui sûreté nucléaire et radioprotection aux études de prise en charge des colis FMA et TFA

Among its various missions, the Industrial and Grand Est Directorate (DIGE) is responsible for the management of FMA and TFA radioactive waste packages, respectively at the CSA and Cires. Together, these two centres form the Ci2A. Within this directorate, the Upstream and Controls (AC) department is responsible for the various tasks necessary for management and which interface with the producers: drawing up acceptance specifications, handling approval or acceptance files, monitoring the quality of the packages, etc. Some producer needs sometimes require adapting the standard management processes for the packages. Special studies are then necessary for this. These are led and partly carried out by the Customer Relations and Solutions (RSC) service within this department. These studies aim, for example, to examine the acceptability of particular waste packages (new conditioning matrices, radiological threshold exceedances, non-standard dimensions, etc.), to define adaptations to the storage centres, to prepare files for requests for significant modifications subject to ASNR authorisation, to develop new industrial solutions for waste management. These studies require the subcontracting of certain lots requiring strong technical expertise, notably nuclear safety, radioprotection studies or support for the preparation of regulatory files.
