Nuclear facilities decommissioning costs around the globe will amount to at least EUR 90 billion by 2040, per international estimations. Segmenting the Reactor Pressure Vessel (RPV) is particularly long and costly, and whose complexity often leads to project deviations. Using laser cutting technologies may help to reduce cost and time in decommissioning operations. It has multiple advantages, such as :
excellent performance on metallic/ceramic material with a cutting capability of up to 200mm in thickness ;
- cleanliness. Cleaner than most of other thermal techniques, especially for dust and fumes ;
- minimization of slag production (secondary waste production) ;
- proven performance and long life in highly radioactive environment ;
- has been paired with a selection of manipulators for various applications in nuclear decommissiong ;
- safety during operation and maintenance (reliable and remotely operated).
CEA is involved in the European LD-SAFE (Laser Dismantling Envrionmental and Safety Assessment) project as part of a consortium with Onet Technologies (France), Equans (Belgium), Vysus Group (Sweden), IRSN (France) and Technatom (Spain).
