  1. R2E Mitigation Project Review of UJ56 relocation options Main contributions from EN/CV, EN/EL, EN/MEF, GS/ASE, GS/SEM & equipments owners A. L. Perrot, EN/MEF & R2E Study Group 5th November 2010

  2. Mitigation options studied Option A: full relocation in the by-pass (A. L. Perrot) Option B: partial relocation in the by-pass & the UJ561 (UJ561 being the CMS exit path) (A. L. Perrot) Option C: partial relocation in the by-pass & the UJ561 finding another CMS exit path (M. Gastal)

  3. UJ56 1rst floor Equipment to be moved : power converters + 17 racks Power converters

  4. UJ56 ground floor - ‘safe room’ Equipment to be moved : 5 racks + internal part of SYAFD01 (fire detection) rack EYP01 (anti-panic lightning), EYC01/02/03 (electric network control), EYU01 (AUG)

  5. Option A: full relocation in the by-pass • N.B. request of the equipments owners: 6 racks in the USC55/machine area and 1 rack in the USC55/CMS area • - Technically feasible • Constraints/consequences: • mini safe – room construction in the by-pass (likely) • interference with transport volume: Power Converter calibrations racks • remaining free space along the USC55 wall before the PAD =20m

  6. UJ561 by-pass RTQX2.R5 RQX.R5 RYCA01-02 RYMCB01-05 EYU01 & 02 – EYP01 & 02 EYC01 à 04 (h=1.8m) RYLB01 RYLC01 mini- safe room ERD1/56 DYPG01 & 02 CYCIP01 GYPOS01 à 03 CYNET01 – RYSC01 EOD1/56 – EOD3/56 EBS1/56 – UPS machine QYC01 à 04 (h=2.00m) CYTIM01 – CYFRE01 (h=2.00m) RYSA01 – 02 (h=2.00m) Oct. 2010- Ph. Orlandi, JC Guillaume EN/EL JP Corso, Y. Muttoni, EN/MEF

  7. USC55 machine area TYCFL02 CYCIB01 DYXF01 RYSA01 - 02 YYACS01 6 racks movedfrom UJ56 1rstfloor to USC55 /machine area SYAFD01 eqptmovedfrom UJ56 ‘safe room’ to USC55/ CMS racks room (S2A19)

  8. Option B partial relocation in the by-pass & the UJ561 (UJ561 being the CMS exit path) • N.B. request of the equipments owners: 6 racks in the USC55/machine area and 1 rack in the USC55/CMS area • - Option B1: install 1 raw of racks in the UJ561= technically feasible • => remaining free thickness for the CMS exit path is 1.2 m • - Option B2: install the mini safe-room in the UJ561 = technically feasible • => remaining free thickness for the CMS exit path is 1.1 m thick Safety requirements concerning exit path (CERN/TIS-GS/2002-03) depends on the number of persons to evacuate and the number of exits foreseen => 0.9m thick for less than 100 persons

  9. Option B: partial relocation in the by-pass & the UJ561 CMS exit path CYTIM01 – CYFRE01 RYSA01 – 02 QYC01 à 04 DYPG01 & 02 RQX.R5 RTQX2.R5 RYCA01-02 RYMCB01-05 RYLB01 RYLC01 ERD1/56 CYNET01 – RYSC01 GYPOS01 à 03 CYCIP01 EYU01 & 02 – EYP01 & 02 EYC01 à 04 (h=1.8m) Oct. 2010- Ph. Orlandi, JC Guillaume EN/EL JP Corso, Y. Muttoni, EN/MEF

  10. Option B: partial relocation in the by-pass & the UJ561 CMS exit path Oct. 2010- Ph. Orlandi, JC Guillaume EN/EL JP Corso, Y. Muttoni, EN/MEF

  11. USC55 machine area TYCFL02 CYCIB01 DYXF01 RYSA01 - 02 YYACS01 6 racks movedfrom UJ56 1rstfloor to USC55 /machine area SYAFD01 eqptmovedfrom UJ56 ‘safe room’ to USC55/ CMS racks room (S2A19)

  12. Civil engineering – Ducts to be drilled

  13. Civil engineering – Ducts to be drilled 5 new ducts Ø mm – length 2m ‘murtympan’ : 5 new ducts Ø 350mm – length 2m

  14. Main work to be performed for both Options A & B • Civil engineering activities: • - drill 4 ducts between UJ56 and by-pass for PC cables, • drill ducts in the wall between by-pass and UJ561 CMS exit path (cables & ventilation) • drill 5 ducts in the wall UJ56- machine • reinforce the by-pass vault structure (under study) • CV activities: UTAs and cooling system installation • EL activities: cables trays displacement/installation, cables installation • Access : sector door to be moved from by-pass to the UL56 (displt of 11 m) • Mini-‘safe room’ construction in the by-pass/UJ561 (under study), • BRAN pipes to be rerouted

  15. Draft time estimate – main activities The work load equivalent for options A/B => identical time estimate • - EL activities: - 15 months (1 shift) • - 11.5 months (2 shifts) • CE activities: • 4 ducts between UJ56/ by-pass - 3 months • 5 between UJ56- machine - 1 month • 4 ducts in the UJ561/by-pass wall: - 3 weeks • CV activities: - 2.5 months (1 shift) • - AFD activities: - 5 weeks (detection interruption 5 days) ( 1 shift) • - Safe room : - 3 weeks ( 1 shift) • Displacement sector door: • GS/ASE: - 2 days • mechanical work :- 1 week negotiation needed with contractor for the options A/B/C compatibility between EL, CE, and CV activities => Planning

  16. Draft cost estimate – main activities • - EL activities: opt A: 2.405 MCHF /opt B: 2.355 MCHF (1 shift) • opt A: 2.555 MCHF /opt B: 2.502 MCHF (2 shifts: 10% manpower) • CE activities: • 4 ducts between UJ56/ by-pass: 200 KCHF • 5 between UJ56- machine: 25 KCHF • 4 ducts in the UJ561/by-pass wall: 40 KCHF • CV activities: opt. A: 420 KCHF/ opt. B: 445 KCHF (1 shift) • - AFD activities: 96 KCHF (1 shift) • - Safe room : 57 KCHF • Displacement sector door: • GS/ASE: 30 KCHF • mechanical work : t.b. estimated for the options A/B/C EL 1 shift: opt. A: 3.233 MCHF / opt. B: 3.2 MCHF EL 2 shifts: opt. A: 3.383 MCHF / opt. B: 3.355 MCHF Provisional budget~ 3.4 MCHF

  17. Open issues To be done after the decision on the baseline for the mitigation option • integration study (details) • precise schedule (co-activities) and impact on other LHC activities • negotiate the 2 shifts scenario with EL contractor • final budget

  18. Time to get ready for installation once baseline mitigation is chosen • Integration studies:- 1 month (completion and compatibility CV/EL/LHC drawings, documentation preparation, approval loop) • - Planning : - 1 month (sequence, co-activities) • - EL activities: - DC/CTR: 1 year (Market Survey for special cables?, supply) • - power distrib. : 8 months (study, supply) • CE activities: - 3 months (offers, contractor, work set-up) • CV activities: - 6 months (Market Survey for special UTAs?, supply) • - AFD activities: - 3 months (supply, work set-up) 1 year and 1 month process Installation in Jan. 2012decision on the baseline end of Nov. 2011

  19. Summary Option A: full relocation in the by-pass = technically feasible Option B: partial relocation in the by-pass & the UJ561 (UJ561 being the CMS exit path) = technically feasible (CMS exit path 1.2m-1.1 m thick) It looks reasonable to assume that the work could not be performed in less than 15 months for a budget of about 3.4 MCHF Decision on the mitigation option is needed this month to be ready in January 2012.
