Radioactive Material Storage (II) Candidates for radioactive waste in SMB managed areas Bat 150, 183, 193, 225, 917, 951, Material declared as waste: 90 m3 (mainly material on euro pallets) 149 magnets from TT4 and TT5 Magnets: ANDRA + HSE-RP are preparing the “Dossier d’Acceptation” (covering all these types of magnets) – June 2017 First pilot magnet elimination foreseen before end of 2017 LS2C 24-Feb-17 EDMS 1760324

Radioactive Material Storage (III) Inventory: All items in Bat 954/955/879 had been re-inventorised, labelled and registered in TREC (clean-up of data base) Data bases: Automatic link and data exchange between TREC-EDH-BAAN AND TREC from design to the final repository of an equipment! (CERN radioactive waste database ISRAM migrated to TREC in 2016) LS2C 24-Feb-17 EDMS 1760324

Radioactive Material Storage (IV) P. Muffat, 2015: Available storage space: 400 euro palettes, No floor space left Required storage space for LS2: 1900 m2 Future: FLEXBUILDING LS2C 24-Feb-17 EDMS 1760324

Radioactive Waste Pilot project - sorting at the source: Booster and SPS decabling campaign: ANDRA container Radioactive Waste in ISR: ~ 8600 m3 Goal for elimination : ~ 4000 m3 (until end 2019) Waste Class Volume in m3 Various metallic waste 300 Cables 1000 LEP modules 2000 Combustible/filters 2016: 1200 m3 (b.t.) eliminated – 310 m3 produced LS2C 24-Feb-17 EDMS 1760324

Why Radioactive Waste Forecast? Internal: Waste storage and elimination management (space, budget) External: “Waste Study” requested on a regular basis by Tripartite (First edition 2012, next edition in 2021 (after LS2)) -> Input to waste storage management of CERN’s host states (long term planning – location/space, budget) LS2C 24-Feb-17 EDMS 1760324

Summary (I) Storage needs for radioactive material and waste from LS2 seem to be manageable (according to best knowledge): new Flexbuilding for radioactive material ISR for radioactive waste (4000 m3 are planned to be freed in 2017-2019) Some specific storage needs like of the ones of LHCb are not yet completely solved The data collection of future, radioactive material to be stored is vital for best practice storage management The data collection of future, radioactive waste is vital for internal (storage, elimination, costs) and external use (disposal planning by host states, costs) LS2C 24-Feb-17 EDMS 1760324

Summary (II) Future radioactive material and waste forecast: Present method of data collection and processing is extremely resource intensive and difficult to manage. The process should be reassessed. A tool should be developed which allows efficient and reliable data collection validation of data efficient data processing application to all over CERN at any time matching with radioactivity levels in the radiation areas Option: integrate forecast for production of conventional waste LS2C 24-Feb-17 EDMS 1760324
