Orano La Hague BNI OPERATION AND DESCRIPTION CHALLENGE NEXT KEY PHASES DEADLINE (*) ASN OBSERVATIONS BNI 38 Retrieval and packaging of waste from silo 130 Short-term safety of the silo with respect to containment or a seismic hazard Packaging within time frames compatible with commissioning of the deep geological repository Cigéo • End of retrieval of solid GCR waste (intermediate-level long-lived waste – ILWLL). • End of retrieval of active effluents and sludge. • End of packaging of ILW-LL waste. 31/12/2025 Retrieval began in February 2020, but technical malfunctions require technical developments in order achieve industrial output rates. The sludge and effluents retrieval scenario has been determined. Studies into the possibility of retrieving the effluents along with the solid GCR ILW-LL waste are continuing. The end-of-retrieval deadlines are therefore pushed back by a few years. Packaging in definitive packages that meet the acceptance criteria for a deep geological repository is pushed back by several decades (**). Retrieval and packaging of the sludge stored in the silos of the Effluent Treatment Station No.2 – STE2 (“Sludge Retrieval and Packaging” project (RCB) Safety of the silos with respect to containment and a seismic hazard • Defining of the sludge retrieval scenario (direct packaging or construction of a new storage facility). • Defining the sludge encapsulation matrix, development then commissioning of the sludge treatment process. • Defining of the definitive packaging process. 31/12/2030 The new sludge retrieval and management strategy was revised in 2022. Orano is to submit a file presenting the planned options for improving the robustness of the sludge storage conditions. The time frames for the start and end of retrieval are therefore pushed back significantly. The packaging in definitive packages acceptable in a deep geological repository will be pushed back by several decades(**). BNI 80 Retrieval and packaging of the waste from the “High Activity Oxide” (HAO) silo and the Organised hull storage (SOC) pools Safety of the silo with respect to containment, a seismic hazard or resistance to an aircraft crash Packaging within time frames compatible with commissioning of the Cigéo deep geological repository • Commissioning of the ILW-LL solid waste and active effluents retrieval unit. • End of packaging of the waste. 31/12/2022 In view of the difficulties associated with operation and maintenance of the planned process, the retrieval scenario was updated in 2021. ASN is examining the applications for authorisation to put the equipment into active service. The first tests are planned in the next few years. Start of retrieval is now pushed back to 2027. The end-of-packaging deadline is pushed back significantly. Partial dismantling of the filtration building at the end of decommissioning Reduction of the interactions with the pools of the spent fuel elements unloading and storage facility (NPH), in the event of an earthquake • Clean-out of the “900 cells”. • Dismantling of the upper storeys. To be defined Completion of dismantling of the filtration building is forecast between 2031 et 2036, and clean-out of the “900 cells” around 2050; these time frames must nevertheless be supported by additional files to be submitted in the coming years. * Deadline as presented in the last file subject to public inquiry or the deadline stipulated by ASN. ** Given the complexity of the operations, it will be necessary to modify Article L. 542-1-3 of the Environment Code. 348 ASN Report on the state of nuclear safety and radiation protection in France in 2022 • 13 • Decommissioning of Basic Nuclear Installations 13
