DEMINERALISED WATER 2/3 Status Works planed during LS2
BA80 & TDC2/TCC2 : Stopped until Nov 2020 BA81 & EHN1 & TT’s : Stopped until Nov 2020 BA82 & EHN2 & ECN3 : Stopped until Nov 2020 Works planed during LS2 General maintenance of the cooling stations Revision of ½ of the demineralised water pumps and motors (changing mechanical seals and bearings) Changing of all the manifolds in TDC2/TCC2 in 2020 (project leader: Philip SCHWARZ TE-MSC_MNC) Changing of valves and actuators of the demineralised water circuit “security valves” in BA80/81/82 Migration from PcVue to UNICOS in BA82/81/82

PRIMARY & RAW WATER 1/2
6
PRIMARY & RAW WATER 2/2 Status Works planed during LS2
CT2 (Primary water) : Running until 18th Oct 19 Cold water pumps : OK Hot water pumps : 4 pumps running out of 5, actually 1 pump redundancy. BA81 (Raw water) : Running BA82 (Raw water) : Running Problems at the users side, running on potable water back up system actually Works planed during LS2 Replacement of the motors of the cold and hot water DONE Replacement of all the valves and non return valves in CT DONE Replacement of reject pumps and connection to the used water pipe. DONE Installation of manual insulation valve into the BA82: Electricity and controls consolidation of CT2 : Oct 19 / Apr 20 New skid for cooling DUNE in EHN1 extension during CT2 stop Sept 19 / Oct 19

New SKID Cooling Racks of DUNE EHN1
Skid to be built - major components are free (chiller, pump, instruments,…)

COMPRESSED AIR 1/2
10
COMPRESSED AIR 2/2 Status Works done during LS2
Building 860 (compressed air production) : Running Works done during LS2 Installation of a flowmeter on the north area distribution pipe Planed in Dec 19 (to be discussed)

East Area Renovation B251 Ventilation Demi Water Cooling
Primary Zone & Mixed Zone HVAC UR-WP-Study (P&ID + 3D integration) - Next steps: Spec Committee (28 May 2019) Installation works: April – July 2020 Commissioning works: Oct – Dec Performance test (with dissipated heat load) – Feb 2021 Demineralised water cooling Magnets, Power Converters Order placed (RAM) - Detailed design and dismantling activities started and according to plan Installation works: July 2019 – May 2020 Commissioning works: Jun-July Nov-Dec 2020 EA hall ventilation UR-WP-Study (P&ID + 3D integration) done – Building ventilation consolidation delayed to post LS2 Destratificators: Offer received (Arceclima) – aligned with estimation Installation works: July-Aug 2019 B251 ventilation UR-WP-Study (P&ID + 3D integration) done Ductwork installation: Oct 2019 ATEX Ventilation UR-WP Ongoing - Installation: Aug-Sept 2020 B251 Ventilation Demi Water Cooling

AD Cooling Towers Status Works planed during LS2
Cooling towers for AD: Stopped for LS2 Cooling works with primary water because the load is to low to use the CT. Works planed during LS2 Replacement of the PLC Dec 19 / Jan 20
13
CONCLUSIONS The north area was build at 1970’s wich makes the installations age at 40 years. CV equipment general life expectancy is between 5 to 20 years. Today all systems are running with redundancy. Primary/Raw water : Automation and control system of the CT2 cooling tower will be all new for better performance after LS2 ... Demineralised water : Replacement of the control system to optimize performance and reduce untimely shutdowns. Chilled water : Cartography of the chilled water network is on going. Ventilation : Units replacements to be provided in future consolidation plans.
