5. 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)

6. 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

7. 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)

8. 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 EDMS

9. Data Collection for Rad. Waste and Material
The origin, the type of item, the type of material (chemical composition), geometrical information (dimension, mass, volume), the quantity, the risks, the radiological information (duration of irradiation, cooling time when applicable, etc.).

11. 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 )
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 EDMS

12. 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
