ASN Report 2022

Aube waste disposal facility Authorised by a Decree of 4 September 1989 and commissioned in January 1992, the Aube repository (CSA) took over from the Manche repository (CSM) which ceased its activities in July 1994, benefiting from the experience gained with the latter. This facility, located in Soulaines-Dhuys, has a disposal capacity of one million cubic metres (m3) of low and intermediate level, short lived waste (LL/ILW-SL). It constitutes BNI 149. The operations authorised in the facility include the packaging of waste, either by injecting mortar into metal containers of 5 or 10 m3 volume, or by compacting 200-litre drums. At the end of 2022, the volume of waste in the facility had reached about 350,000 m3, or 37% of the authorised capacity. According to the estimates made by Andra in 2016 in the concluding report on the CSA periodic safety review, the CSA could be completely filled by 2062 rather than 2042 as initially forecast. This can be explained by having better knowledge of the future wastes and their delivery time frames, as well as by an optimisation of waste management through the compacting of certain packages. ASN considers that the CSA is operated satisfactorily in the areas of safety, radiation protection and the environment. The inspections conducted in 2022 showed an appropriate organisation for radiation protection and emergency management, and compliance with the deadlines for the commitments made during the second periodic safety review of the facility. Deep geological disposal centre project ASN considers that the scientific experiments and work conducted by Andra in the underground laboratory at Bure continued in 2022 with a good standard of quality, comparable with that of the preceding years. Furthermore, on the basis of the work carried out since ASN examined the Cigéo project safety options dossier in 2017, Andra filed the Creation Authorisation Application (DAC) for this deep geological disposal centre (see chapter 14 of the full ASN Report) with the Minister responsible for nuclear safety on 16 January 2023. 60 ABSTRACTS – ASN Report on the state of nuclear safety and radiation protection in France in 2022 Regional overview of nuclear safety and radiation protection • GRAND EST •
