26/05/20105 Services difficult to relocate martin.gastal@cern.ch Remaining issues to clarify: →What is the best path for the gallery to connect with UJ56 →Modification of metallic staircase →Relocation of services in the way of gallery (CV, EL, ASE...) →Could this be avoided →How to evacuate spoil and ventilate worksite: J Osborne to assess situation and make recommendations →Safety issues: Green light from G Roy & CMS GLIMOS →Access control issues: Installation of a new interlocked blast door + move of existing UJ561 sector door + changes in LACS + update of documentation: Estimated cost to be produced by S Di Luca and CEGELEC

26/05/20107 UJ56 1 st floor 24 racks How many racks need to be relocated and where should they go (USC55 vs UJ561)? List to be put together by M Gastal & JC Guillaume Rack owners will be contacted in turn. martin.gastal@cern.ch
8
26/05/2010martin.gastal@cern.ch8 Status so far: 24 racks currently installed 6 racks would stay in the UJ56 11 racks would be relocated
9
26/05/20109 UJ56 1 st floor Power converters TE-EPC to be contacted to collect feedback on proposal to relocate PCs to UJ561 C Coupat 25/05: Solution proposed is acceptable Space required around equipment for installation and maintenance C Coupat 25/05: 1.4m of space in front of front space martin.gastal@cern.ch
10
26/05/201010 UJ56 1 st floor 24 racks + Power converters What power dissipation is to be expected from rack + Pconverters? Guideline for relocation and impact on CV systems G Peon to be contacted by M Gastal martin.gastal@cern.ch
11
26/05/201011 UJ56 Gnd Floor How many CV pieces of equipment need to move? G Ducret met on 25/05 @ 16:00 martin.gastal@cern.ch PLC for UJ56 and tunnel ventilation Preference for relocation in USC55 “ctrl room area” Switchboard for water pumps “eau brute”, used for fire fighting Preference for relocation on surface
12
26/05/201012 Additional shielding: width calculated to be 1m possibly with a 40cm roof shielding martin.gastal@cern.ch
13
26/05/2010martin.gastal@cern.ch13 → Can the slab sustain the additional weight? → Consultant to be commissioned by GS-SEM → Cavern floor is founded directly on rock → Total compression force produced by shielding would only be a very small percentage of what concrete can take. → Could we build a shielding roof of 40cm? From CE point of view YES
14
26/05/201014 Additional shielding: → How can the shielding wall be assembled? → No crane available → Do we need to remove cable trays under false floor? → Where should the safe room equipment be stored during erection of the wall? → Do we need to remove the metallic structure of the 1 st floor? → New generations of switchboards to be foreseen martin.gastal@cern.ch
15
26/05/201015 New layout of the safe room: → How do we maintain the General Services, safety lights, AUG system during the re-organisation of the safe room? → Could the 48V network be hooked up on CMS? → Should the ventilation system be modified? Y Body to give advice → All pieces of equipment are cooled down by air martin.gastal@cern.ch
16
26/05/201016 Increasing the cable tray capacity between UJ56 and UP56 → Insertion of service ducts through coring – 40cmØ & 8m long. → 4000CHF/m → How many will we need? 4 as first approximation → Impact on ventilation and air flows? → Radiation protection implications? Smaller Ø preferred ~25cm Cooled cables Ctrl cables DC Power cables martin.gastal@cern.ch
17
26/05/201017 Increasing the cable tray capacity between UJ56 and UP56 → How to resolve the bottle neck in UP56? → New idea: reduce the size of the ventilation duct Cooled cables Ctrl cables DC Power cables martin.gastal@cern.ch
18
26/05/201018 Increasing the cable tray capacity between UJ56 and UP56 → How to resolve the bottle neck in UP56? → New idea: reduce the size of the ventilation duct DC Power cables Inject fresh air from USC55 martin.gastal@cern.ch
19
26/05/201019 Increasing the cable tray capacity between UJ56 and UP56 → Modify t UP56 lining Smoother edge Only very small chamfer possible without affecting the structural stability of the tunnel martin.gastal@cern.ch
20
26/05/201020 Optimisation of space occupancy in UP56 → How much equipment can be brought in? → Space budget? → Cooling budget? → PConvs cooled by water → Racks cooled by air → What new CV systems (chilled/mixed water) should be installed? martin.gastal@cern.ch
21
26/05/201021 Optimisation of space occupancy in UP56 → How should the ventilation system be modified? → Needed if unified UJ561? → Sections of partition wall could be removed martin.gastal@cern.ch
22
26/05/201022 Optimisation of space occupancy in UP56 → How should the ventilation system be modified? → Needed if unified UJ561? → Sections of partition wall could be removed → Fresh air supplied by USC55 and/or UL55 → Extraction through ventilation gallery (new opening) → Sector door to be moved to UP56 → Should we add sector doors to close off the bypass? martin.gastal@cern.ch Access to the modified UJ561 would be more restrictive than the access required for UJ56
23
26/05/2010martin.gastal@cern.ch23 Reinforcement steel bars are linked to the crown of the tunnel. Removing the wall might induce rock settlements, cracking. GS-SEM could further investigate using consultant... Openings could still be considered
24
26/05/201024 Optimisation of space occupancy in UP56 → Ho w much cable tray capacity can be found if ventilation duct can be spared → How do we handle pieces of equipments during the relocation? → Installation of a fire detection system → On what side should the cable trays to USC55 ctrl room be installed? martin.gastal@cern.ch
25
26/05/201025 Link between UJ561 and USC55 control room → What should be the position of the service duct? → What thermal load would be brought on to the USC55? → Water cooling: none → Ventilation? martin.gastal@cern.ch
26
Underground Ctrl room USC55 26 24 racks (uj56 du 1 er ) → Integration to be studied Draft 3D model of Mezzanine control room to be prepared for presentation at CMS 26/05/2010martin.gastal@cern.ch
