1 EN-CV Progress EHN1 Extension Project Jérôme Rodary EN-CV-PJ 2016/01/14

2 Contents 1. Works for cold boxes 2. North wall dismantling 3. Integration status 4. Future design activities

3 1. Works in progress Cold boxes works All CB are still stopped: switch from drinking water to raw water to be performed TE-CRG is performing some works on CB during YETS  Dates to be scheduled between TE-CRG & EN-CV: TE-CRG will confirm intervention dates to EN-CV (no critical regarding NW dismantling !)

4 2. North wall dismantling Works completed : (already discussed) firefighting network interception chilled water disconnected barrack HNA 910 mixed water station removed (north wall) old fan coil removed from barrack HNA 494 raw water network interception (several places) Dismantling status updated (13 January 2016) : Completed Scheduled Not possible : access issue Completed Technical visit done with contractor – Works scheduled for week 3 Completed

5 3. Integration status GAr extraction system & hall ventilation : ~ 90 % Piping networks & cooling systems : ~ 80 % Some integration issues to be discussed : See slides in appendix

6 4. Future design activities Preliminary design data for EN-EL ( given by EN-CV the 19 October 2015 )

7 4. Future design activities Chilled Water (CW): Extension of the network in the future galleries Hypothesis for the design - confirmed by EN-MEF on 05 November 2015 : Additional flowrate: ~ 18 m3/h (for n.8 barracks fan coils) Additional cooling power (for n.8 barracks 6.3 kW fan coils): ~ 50 kW Other : NO CW network extension proposal inside EHN1 extension area

8 4. Future design activities Raw Water (RW): Extension of the network in the future galleries – confirmed on 17 December 2015 Hypothesis for the design – not confirmed (urgent !) : Additional flowrate (for n. 40 ? racks) : ? m3/h (to be confirmed) Additional cooling power (for racks) : ? kW (to be confirmed) Additional cooling power for (n. 3 ?) cold boxes : NO (confirmed by Johan Bremer on 03 November 2015) Water cooling requirements for racks to be given: Racks locations (barrack ?) Thermal load Inlet temperature, ∆T Max allowable pressure ∆P Nominal diameters of connection Any relevant information,…

9 4. Future design activities Compressed Air (CA): Extension of the network in the future technical gallerie Hypothesis for the design – given by Johan Bremer on 03 November 2015 : ‘Cryo’ users (for cryostats valves & instrumentation) : 10 m3/h @ 9 bar Additional users (for tools,…) : NO

10 4. Future design activities Demineralized Water (DW): Extension of the network in the future technical gallerie Hypothesis for the design - given by Philip Schwarz on 02 November 2015: Additional flowrate (for new magnets) : 64 m3/h - to be updated by Philip & Ilias Additional cooling power (for new magnets) : 2 513 kW - to be updated by Philip & Ilias Additional cooling power (for power converters) : 0 kW Other : NO Currently : DW network pumping capacity is not sufficient to ensure these requirements !

11 4. Future design activities Domestic Water (DoW): No extension will be performed in the extension area (confirmed on 15 October 2015) Note : Only DoW piping removal will be done to free the EHN1 north wall. CV will take care to not leave ‘dead branches’ once the works realized. Fire Fighting (FF): Extension of the network in the future area Hypothesis for the design : According the ‘EHN1 extension safety meeting’ held on 09 October 2015 (see MoM) Number of RIAs to be installed: n.6

12 4. Future design activities Heated water for 2 new AHUs: Hypothesis for the design : Existing hot water substation will be re-used Hot water piping network will be extended

13 4. Future design activities User Requirements missing  some data have been collected but not all ! EN-CV needs technical data & requirements for designing the future extended networks as listed below  UR shall be confirmed as soon as possible for pre sizing all fluid networks and checking pumping capacities ! chilled water (for HVAC purposes) chilled water (for cooling down other some equipments) compressed air raw water ! demineralized water ! fire fighting system gas extraction (other gases except GAr ?) REMINDER: Deadline to collect all the User Requirements was : 12 November 2015 !

14 Thank you for your attention
