1. MKE4 Rearrangement -Updated Drawings -Visit to ECA4 -Visit to LSS4 -SPS Safety File -Safety during intervention MKE4 Rearrangement - TCM 25 August 20151

2. Drawings ECA4 – Present configuration MKE4 Rearrangement - TCM 25 August 20152 Drawings for present configuration were found ! - Drawings now up to date. - Needs to be validated and published to CDD (Drawing number problem ?)

3. Drawings ECA4 – Future configuration MKE4 Rearrangement - TCM 25 August 20153 - Drawings up to date. - Minor corrections requested - Needs to be validated and published to CDD (Drawing number problem ?) Should we show the spare parts (PFN/ switches/DB) ?

4. Drawings LSS4 – Present configuration MKE4 Rearrangement - TCM 25 August 20154 - Drawings up to date for present configuration. - Needs updated drawings for future configuration. -Needs to be validated and published to CDD  Required for ECR ! LSS4 Integration drawing to be updated by EN/MEF and TE/VSC

5. Visit to ECA4 – Water pipes MKE4 Rearrangement - TCM 25 August 20155 Two visit with people from: TE/ABT, EN/MEF, BE/ASR, DGS/SEE, etc… Water distribution for GEN1: -Remove water pipes on ground -Remove clarinette behind pillar => Done by FPS. (GEN2 is connected to another clarinette).

6. Visit to ECA4 – Cable support MKE4 Rearrangement - TCM 25 August 20156 Cable support for GEN1: -Remove cables -Remove cable support / pillars Copper plan to be cut and removed => Done by FPS. Cleaning of concreate after removal of copper plan (glue): => Done by external company ? (Patrick Vincent EN/MEF)

7. Visit to ECA4 – Barrier not on wall MKE4 Rearrangement - TCM 25 August 20157 Reduction of kicker zone: -Remove old barrier and move it to close zone. => Done by external company ? (Patrick Vincent EN/MEF) Problems: -Water pipes -Cables support -Wall not vertical => Difficult to completely close the kicker area HSE (Ana): L’idéal serait que les parois coupe-feu vont jusqu’au mur pour avoir une étanchéité maximum du local et par conséquente la meilleure protection contre un possible feu.

8. Visit to LSS4 / LSS6 during next TS Visit of LSS4 / LSS6 during next TS: - Impact: 68200 / 68484– Waiting for approval - With people from TE/ABT, EN/MEF, BE/ASR, DGS/SEE, etc… => Please give me the list of people to add to the Impact. MKE4 Rearrangement - TCM 25 August 20158

9. SPS Safety files Contact BE/ASR : Anne Funken / Lisa Kobzeva SPS safety file not yet available, in preparation. -BE/ASR will prepare the safety file. -Nothing to do from our side, just answer questions… -Needs a visit to LSS4 (planned for next TS). -Needs updated drawing Present / Future Example: PS safety files available on EDMS: CERN-0000094160 => Invite Lisa or Anne to explain about SPS safety file in another TCM ? MKE4 Rearrangement - TCM 25 August 20159

10. SPS Safety files - Questions Already answered some questions (Thanks to Francesco): -Type of oil in generators: Code SCEM : 57.97.20.099.9 : https://edh.cern.ch/edhcat/Images/192536/57.97.20.100.FSFR.pdfhttps://edh.cern.ch/edhcat/Images/192536/57.97.20.100.FSFR.pdf -Quantity of oil in generators (ECA4): -1x PFN = 1200 L -2x Switch = 1000 L -1x TDR = 10 L => ~ 3210 L per generator Total present configuration: 5x generators = ~16000 L Total future configuration: 1x generator = ~ 3200 L -Type of material used for barrier = Fire resistant. -Etc..
