6. Removal of hot equipment TCSC removed first and brought to B.955 3 splitter2 magnets and 2 MDLV removed and stored in TDC2 Various beam monitors, BLM and vacuum beam pipes

7. Cooling and ventilation upgrades IEFC  New chilled water pipes (200 m DN 200)  New cooling coils in all AHU’s  AHU cabinet (40 years old) quite in good shape  Demineralized water circuit: 20 new valves  Challenge: asbestos removal

8. Civil Engineering IEFC Repair of the TDC2 roof joints: 3 joints have been fitted with a metallic gutter driving water and bitumen to 3 retention boxes. Repair of the mezzanine floor: Resin flooring

9. Civil Engineering: drain network maintenance IEFC Contractor Vallier checked all the manholes and inspection chambers High pressure cleaning Cleaning water collected and RP checked before disposal Sludge treated as radioactive waste

10. Civil Engineering: various repairs IEFC New, extension of, repair to water collecting gutters Exchange of all remaining PVC pipes by PE pipes New drain connection

11. Heavy handling equipment IEFC PR544 maintenance and test Power supply rail (feeding TT20 for transport vehicles) has been removed from TDC2

12. Magnet upgrade IEFC  One manifold dismounted in order to estimate time needed for future exchange  Cooling flexible replacement completed in TDC2 (joints replaced)  About 120 seals exchanged

13. Magnet upgrade  Splitter rails and vacuum tank

14. Cabling activities Re-routing of 5 Cable trays (5x40m) Replacement of 70 DC and 42 control cables Installation of 10 new cables (new requests) IEFC Gangway Average 100µSv/h. Max: 500µSv/h Courtesy of I. Moya

15. IEFC Cabling activities Control  Power  General services  New situation

16. Replacement of emergency and conventional light fittings Total 66 emergency light fittings (Not compliant with current standards) Total 338 conventional light fittings Replacement of AUG buttons Replacement of power distribution outlets Installation of cable distribution for vacuum pump heaters IEFC Emergency radiation resistant LED light fitting High Power LEDs hung from walkway TCC2 TDC2 Conventional light fittings Low voltage activities Courtesy of J. Devine

17. Target refurbishment Preparation in EHN1 cleanroom: Production of new monitors and target boxes for target stations T2, T4, T6 & T10 + spare survey and vacuum & motorisation tests IEFC Courtesy of D.Grenier

18. T2, T4 and T6 target refurbishment In TCC2: Proximity cabling has been renovated Old monitors and target boxes remotely removed Dedicated shielded container for long term storage in B. 954 and 955. Re-installation of new monitors and target boxes currently in progress IEFC Courtesy of D.Grenier

19. Upgrade of 12 XTAX tables: Removal of spiral springs (screw protection) Jacks greasing Functional test of each tables Cleaning and maintenance of the base plates Realignment of XTAX4 XTAX table upgrade

20. Vacuum consolidation New beam pipes (100m) New ion pumps (10 units) Heated collars Vacuum consolidation

21. New TCSC collimator New beam instrumentation A few new units Maintenance of 40 beam instruments Collimator & beam instrumentation

22. Outline  Objectives and schedule  Completed activities  Dose management & budget  Conclusions IEFC

23. Dose management IEFC Operational dose  Cumulated collective dose on 02.10 = 82539 uSv

24. Maximum individual dose on 04.09 = 2033 uSv # of participants: 362 Dose management

25. Budget IEFC

26. Outline  Objectives and schedule  Completed activities  Dose management & budget  Conclusions IEFC

27. Conclusions IEFC  The TDC2/TCC2 consolidation activities are successfully completed, within schedule, budget and with no major problem.  The corrective and preventive maintenance recently implemented will reduce corrosion of the vacuum equipment and reduce machine downtime in the future operation of the beam lines.  Individual dose management has been challenging for some groups.
