All nuclear facilities, whether reactors, fuel-cycle front-end facilities (conversion, enrichment, fuel-fabrication plants) or spent-fuel processing plants, generate operational waste. In particular it is generally estimated that about 100 m3 of operational waste are produced every year just by each power reactor.
Such waste includes, for instance, the ion-exchange resins produced in reactor circuits or the operating filters, both of which contain a large amount of cobalt-60 activation products. A significant process is necessary to ensure that all operational residues are sorted, measured, treated, conditioned, packaged and stored or disposed of under good operational safety and long-term safety conditions. Those activities must also be carried out at the most cost-efficient rates.
The selection of the disposal concept has an impact on all phases of the waste-management process, especially on the producer's premises beginning when the radioactive waste is produced. Therefore the waste manager must intervene very early in the process in order to ensure its entire consistency.
The objective is to set up an iterative process that includes the following steps:
Andra is responsible for managing all radioactive waste produced in France. It benefits from 40 years' experience in the management of the waste coming from the French nuclear reactors, including all fuel-related facilities.
The Agency is currently operating two disposal facilities: one for shortlived low- and intermediate-level waste (CSFMA) and the other for very-low-level waste (CSTFA). In accordance with waste production rates and with a very good safety record, both facilities accommodate almost all operational waste generated in France. Andra also ensures the active monitoring of a third disposal facility, the Manche Disposal Facility, which is now in post-closure monitoring phase.
Moreover, the Agency intervenes on the overall processing of the waste and prescribes the wasteacceptance criteria to be met by the producers before they send their waste to Andra's disposal facilities. Hence, it implements integrated solutions for radioactive waste management, from initial production until final disposal.
