Why consolidation ?

Non compliance to present safety and technical norms Ageing equipment everywhere

Well beyond manufacturer recommended lifetime (reliability) Impossibility to find spares Unsafe to manoeuver

Layered installation of equipment Evolution through the addition of strata instead of an

integrated approach Radiation damage

Mostly cables and fibers but also emergency stops Overcrowded passages and tray Needs beyond the EL 2025 program (including major

HV Upgrade & Consolidation projects)

12 September 2013


Methodology

Study the different domains Risk analysis for each to

determine priority done or in preparation

The costs quoted are based on supply contracts and experience (e.g. cabling)

Systems thinking rather than replacing like with like

Every consolidation item is documented in detail in EDMS

Domains of Consolidation

12 September 2013

SPS machineCritical state 1: Point 5 surface, shafts and

underground Point 4 surface, shafts and


underground

Critical state 3: Point 6 surface, shafts and




underground

Critical state 5: TT60, TT70

Shafts are the most critical areas for all points.

PS-Complex and Meyrin site Critical state 2: Bld.360-361 (under the Booster),

rooms BCER, BOR, BAT Bld.354, room CCR et MNR, gallery

815 Gallery TP9 between Bld.354 and

Bld.361 Bld.353 (ring centre) and tunnel of PS

Bld.350 accelerator TT2 entire tunnel (from Build. 269 to

TT2A towards nTOF)

Critical state 4: Bld.2001 (upstairs), cable

connections from Build.2008

Priorities for Cable Clean Up



▶ Taking into account the LIU project and the priorities for overcrowded areas, we propose to clean up during LS2:▶ the booster complex ▶ the SPS-P5 during LS2

Concerns ~10’000 cables Total estimated cable length: 1500 km 14 MCHF 8 FTE

Cable Clean UpCleanup cables on overcrowded areasCannot pull cables in the proper technical wayThis situation is general for SPSIn some cases, cables cannot be installed anymore

EDMS 1309198 & 1309230



In order to exchange the cables in the irradiated areas of the SPS to ensure operation, two cable replacement campaigns similar to the one which is taking place in SPS TS1+ will have to be organized during LS2

These two areas will be selected after the conclusions of the RIAC and other constraints

The procurement of new cables for these campaigns will start already in 2016-2017.

The studies to prepare these campaigns as well as the procurement of cables will take place in advance of LS2 (2015-2017). The budget for these is included in this request.

Number of cables to be replaced: ~1200Total estimated cable length: 600 km 4 MCHF (1.1 MCHF already funded) 5 FTE

Irradiated Cables

EDMS 1309192



Consolidation of the network the dimensioning of the existing, CERN-wide, infrastructure to cope

with new users needs. This was until now mainly paid by the IT/CS Group.

the replacement of radiation sensitive fibres in all radiation areas

Total estimated cable length: 600 km 6 MCHF 10 FTE

Fibres

EDMS 1309213



Tools for management and monitoring

Creation and population of of an optical fibre database “Fibrothèque” based on the existing Cablothèque.

Implementation of an on-line transmission quality monitoring system based.

Total estimated 0.9 MCHF for the Fibrothèque 0.23 MCHF for the Online Monitoring ToolsBoth including manpower

High Voltage Network Consolidation of old protection

relays Necessary upgrade on functionalities after

the consolidation of the 66 kV protection system (communication, differential..)

Poor reliability due to ageing of electronic components (e.g. drift of time constants)

200 relays to be replaced, 4 MCHF

Consolidation of the 400 kV protection system

RTE now requires an additional breaker (incomer) in order to comply with the French regulations

Consolidation of the protection system: Necessary upgrade on functionalities after the

consolidation of the 66 kV protection system (communication, differential..)

Separation from 18 kV pulsed system (room, 48Vdc, etc.)

High Voltage Network Consolidation of the PS and administrative areas in Meyrin:Necessary to withstand increasing short circuit current and necessary to extend switchboards not anymore available on the market.

Consolidation of two substations (ME16 & ME49) Operation problems Old cubicles will be reused as spares

Consolidation of HV power cables Larger section External insulation in very bad shape

Consolidation of distribution transformers Cope with present power demand Continuous effort to eliminate non compliant transformers Switch from oil transformers to dry type Oil transformer pits not compliant with CERN safety rules

Generators No more spares for the generator sets The cooling system and various mechanical

components are at the end of their lifetime 3MCHF

test reports) Control system needs upgrade (com, safe

connection, etc.) 0.5 MCHF
