1. Building 867 Project Status Presented by Tony Fowler, TE-ABTon behalf of the Project Team IEFC Meeting 16 November 2012

2. Layout 2010 Rez de chaussée Jura South North Etage Salève The project’s mandate was to provide a centrally managed facility for the maintenance and repair of radioactive components on the Prevessin site.

3. Layout 2012 • The final layout was based on extensive consultation with the various User groups. Originally it was planned to make the entire building a controlled-access Radiation Area however the need to keep certain support activities in close proximity required a compromise. • The two central blocks, comprising ~7640m2 of workspace, approx. 80% TE Dept., 10% BE Dept. and 10% EN Dept., are designated as controlled access with personnel access via two special changing rooms. The central aisle main doors will be condemned except for fire service access. • Non-radioactive assembly, machining and storage support activities occupy ~2000m2 , approx. 50% TE Dept. and 50% EN Dept., in the two outer blocks. A protocol for work on radioactive material will be required for the TE-VSC surface treatment facility

4. Controlled Access Points • Personnel access (PAD) will be via two dedicated changing rooms. South access will contain male and female facilities, north access only male due to space restriction. • Equipment access will be via adjacent MAD • Each User zone will have individual door access control • Safety reception of South Access Point was made on 15 Nov. With certain reserves, it should be authorized for use very shortly. This is a prerequisite for new authorization of destructive work on radioactive equipment, e.g electronic cards EQP EQP EQP EQP

5. PAD/MAD Men’s PAD MAD South changing rooms • A decontamination cubicle is available for emergency use. Used water will collected in a below-ground retaining tank outside the building • A changing room for people of reduced-mobility is available in the South changing room block. Suitable facilities are also available in the two sanitary blocks. • Special dispensation will be made to allow wheelchair access via the MAD Men’s changing room

6. Washbasins • Running water is necessary in certain User zones to allow cleaning of hands or material during some work processes. • Discharge of this water directly to the normal drainage system is not admissible due to the risk of contamination. • Specially designed mobile washbasins have been constructed to allow collection of waste water in a small (200l) retention tank. Once full, the RP technician should be called who will check a sample for contamination. If negative, the water will emptied into the normal drainage. If positive, the washbasin will moved, on its own wheels, to the south access point where it can be emptied to the external storage tanks. An alarm will signal when the tanks require emptying.

7. Status of User Zones • TE-MSC-MA and TE-MSC-MM zones remained largely operational during the building’s reconfiguration and retained their Supervised Radiation Area status • Other zones were given Supervised and Controlled Radiation Area Status on completion of their reconfiguration on condition that no destructive work could be done on activated material. Destructive work will only be permitted in User zones once final safety acceptance tests have been completed and the south access point changing rooms and decontamination facility are functional. • All infrastructure work is complete except for installation of some Ethernet points, installation of radiation monitors and cabling of the controlled access system. This should be completed by early December. • It is foreseen to put the central zone under access control in January 2013.

8. TE-MPE The infrastructure is completed and the laboratory is awaiting a final safety acceptance visit. If no major problems are discovered (none are anticipated following an interim safety inspection some months ago) then it will be possible to classify the zone as a Supervised Radiation Area. For destructive work (desoldering) to be allowed a changing room and a decontamination shower facility need to be available; this should be the case before end of November.

9. TE-ABT-FPS • Sixteen high voltage kicker test cages have been delivered. Certain of these have provisional Supervised Radiation Area classification. • The clean-room facility is operational. It contains certain fixed facilities for ABT equipment however areas can be made available for other groups on an occasional basis • The assembly area is operational however the total area of ~500m2 is barely sufficient for exploitation activities. New-build assembly (e.g. Linac4, ELENA) will require additional space as well as additional test cages.

10. TE-ABT-SE • The Septa area infrastructure is complete and provisional RP classification has been given prior to a final safety inspection in December • Some Septa activity in B904 is still underway due to lack of space in B867. • A total of eleven new test zones have been created and installation and commissioning are well advanced. • The opportunity was taken to install a state-of-the-art system using personal RFID keys to control access and tagout/lockout of the high voltage test zones both in the Septa and Kicker zones

11. EN-STI The zone is operational but not yet RP classified – safety inspection scheduled early December . For want of alternative space, EN-STI are currently using the area as workshop. this activity now needs to cease to allow the safety inspection to take place under appropriate conditions. A sealed cleaning/de-jacketing room has been constructed at the end of the zone. Separate access will allow use of this facility by other groups

12. BE-RF Before • Originally no modifications planned , but: • Dismantling of large concrete bunker • Replacement of perimeter grill with new white panels • Floor resin • Dismantling of small office • Building of new ventilated semi-clean-room • Provision of new demineralized manifold • Zone operational but not yet RP classified – safety inspection planned early December After

13. EN-MEF Zone operational and classified Supervised Radiation Area Final safety inspection planned in December

14. TE-MSC-MM • Nothing was originally planned for TE-MSC-MM however the following have been installed: • New white panelling • New false floor panel (fireproof) • Floor resin • To minimize fire risk the technical offices should be re-panelled (possible without demolishing the whole structure)

15. TE-MSC-MA Cleaning room The zone is operational and classified and a final safety inspection will be made before end 2012. A sealed room has been built to allow cleaning of radioactive vacuum chambers in situ in magnet yokes. A new 30Tonne capacity overhead crane, replacing one of the two 15T cranes on the Saleve side, has allowed a further ~600m2 area to become fully exploitable

16. BE-BI The infrastructure is completed and the laboratory is awaiting a final safety acceptance visit. If no major problems are discovered (none are anticipated following an interim safety inspection some months ago) then it will be possible to classify the zone as a Supervised Radiation Area. For destructive work (desoldering) to be allowed a changing room and a decontamination shower facility need to be available; this should be the case before end of November.

17. TE-VSC The infrastructure is completed and the laboratory is awaiting a final safety acceptance visit. If no major problems are discovered (none are anticipated following an interim safety inspection some months ago) then it will be possible to classify the zone as a Supervised Radiation Area. Some delay may be encountered if the zone needs to be used to temporarily house the ATLAS Beryllium chamber

18. Traceability (TRAC) System RP technician office Buffer zone north Buffer zone south Buffer zone south • Each of the buffer zones will be equipped with a PC and bar-code reader to allow the TRAC system to be implemented. This should be in place by end 2012. • An RP technician will be present full-time on site. • Each of the individual User zones is expected to have its own Radio-Protection Expert (RPE) to perform first level measurements. • A public meeting will be organized to explain procedures for personnel and material access to and from the zone and general modalities of operation of the facility.

19. Outstanding Issues • Building consolidation • Consolidation of the heating and smoke extraction systems will be made by GS Dept., probably starting 2013. • Consolidation of the lighting system by GS Dept. is underway • Radiation Area demineralized water circuit • Building 866 (TE-EPC power supply test zone) was discovered to be connected to this circuit. As it is required only on a very occasional basis, the source will controlled by an RP consignable valve. Analysis of the water quality will be made by RP before supply to B866.This arrangement may need to be reviewed if TE-EPC requirements change. An autonomous water station would cost ~150kCHF. • Building 867bis • Both TE-ABT and EN-STI are in urgent need of additional space for non-rad. activities equivalent to those done in B867. To allow synergy a new building of minimum 1500m2 surface is required adjacent or contiguous to B867. Any future extension of the radiation areas in B867 would require rehousing of the present B867 non-rad. activities and an extendable B867bis should be foreseen. Ten pigeons have been caught since traps were laid by ISS Pest Control in September. Measures to permanently avoid pigeon infestation are costly (plastic curtains on doors, grills on smoke extraction vents, introducing raptors on a regular basis) and GS Department’s help has been solicited.
