CEA Cadarache BNI OPERATION AND DESCRIPTION CHALLENGE NEXT KEY PHASES DEADLINE (*) ASN OBSERVATIONS BNI 54 Decommissioning of the cryogenic treatment facility for final clean-out and remediation of the structures and soils Safety of the operations with respect to the risk of dissemination of radioactive materials • Decommissioning of the cryogenic treatment process chambers. • Characterisation of the soils under the facility. 06/03/2024 This priority operation in the CEA’s “decom/waste” strategy began in 2021. A decommissioning decree modification request is expected in the first half of 2023. BNI 56 Retrieval and packaging of the waste stored in the trenches Risk of flooding by water table upwelling • Develop packaging routes for certain particular types of waste. • Design automated means of retrieval. To be defined The retrieval scenario for the waste in the trenches is to be transmitted to ASN at the end of 2023. Retrieval and packaging of all the intermediate level bulk waste present in the old pits (“vrac MI” (bulk IL) project) Safety of the pits containing waste with respect to a seismic hazard • Construction of a new buildings and putting into service an entirely automated retrieval process requiring substantial preliminary operations • Defining the definitive packaging processes To be defined ASN is currently examining the decommissioning file. The “vrac MI” project is at the detailed design study stage. The “ATC” project is at the preliminary design study stage. Retrieval and packaging of all the waste present under the hangars (“ATC” project) Safety of the hangars containing waste with respect to a seismic hazard To be defined * Deadline as presented in the last file subject to public inquiry or the deadline stipulated by ASN. CEA Fontenay-aux-Roses BNI OPERATION AND DESCRIPTION CHALLENGE NEXT KEY PHASES DEADLINE (*) ASN OBSERVATIONS BNI 165 Packaging of the ILW-LL waste in PETRUS drums and characterisation of the waste from the decommissioning of the PETRUS unit Access to the contaminated silos under the PETRUS unit • Construction of the new waste transfer and packaging enclosure (ETCB). • Development work in order to accept and remove the waste drums from decommissioning of the equipment of building 18 (EDB). 01/07/2017 ASN is currently examining an application to modify the decrees authorising decommissioning of BNIs 165 et 166, for which some deadlines have already been exceeded. In view of the numerous technical and organisational difficulties, particularly the lack of knowledge of the initial state of the shielded cells containing legacy waste, the end-of-retrieval deadline will probably be pushed back by several decades. BNI 166 Retrieval of waste stored in the pits of building 58 of BNI 166 Retrieval of waste to allow decommissioning of the facilities situated in a highly urbanised area Construction of the new measuring and packaging equipment. 01/07/2018 * Deadline as presented in the last file subject to public inquiry or the deadline stipulated by ASN.
