5. 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

7. CT2 electricity and controls consolidation

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

9. 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)

11. 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)

Demi Water Cooling

12. 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.
