  2. SCOPE OF THE CONVENTIONAL FACILITIES Site Reference site for programme, costs and schedule Site characterization Site preparation for construction (earthwork, roads, …) Buildings Front End / Linac tunnel / Klystron buildings Ring buildings Targets and instruments buildings Beam stop buildings Central helium and RF test buildings Central laboratory and office building Infrastructures Water systems and associated networks (potable water, cooling, … ) HVAC Electricity Computer network PAUL GIOVANNONI date : 24/10/2014

  3. CONVENTIONAL FACILITIES IMPACT ON THE ESS PROJECT Conventional facilitiescan easily represent about 30% of the total project budget and are inevitably on the critical path of the project time schedule To control conventional facilities costs and project schedule we have to : -identify main possible technical options for each conventional facilities subsystem - associate to each of them a cost estimate as precise as possible - adopt the most economical (combining investment and operation) technical options - analyse the impact on the planning of construction We use : SNS, CONCERT and Vol III of ESS programmes PAUL GIOVANNONI date : 24/10/2014

  4.

January 2002 : Presentation to the TAC of main technical options PAUL GIOVANNONI date : 24/10/2014

  8. Klystron building Retaining wall 1.5 m Wave guide Linac tunnel Chase LINAC TUNNEL TECHNICAL OPTIONS (cont’d) SNS type option : Klystron building very close to linac tunnel Advantages : - wave guides length is limited - schedule : possibility to build linac tunnel and klystron building independently and in parallel Klystron building Retaining wall 1.5 m Wave guide 7 m 8 m 5 m 5 m Linac Drawbacks : - retaining wall results in increase of cost in comparison with CONCERT option tunnel Chase PAUL GIOVANNONI date : 24/10/2014

  9. LINAC TUNNEL : TECHNICAL OPTIONS (cont’d) CONCERT option : light metallic structure for the klystron building Klystron building Earth material Metallic siding 8 m 7 m 11 m 9 m Wave guide Linac tunnel 3.5 m 5 m Advantages : - limitation of the klystron building cost - schedule : possibility to build linac tunnel and klystron building independently and in parallel Drawbacks :Length of the wave guides is very long PAUL GIOVANNONI date : 24/10/2014

  10. SIZE OF THE RETAINING WALL FOR RADIOLOGICAL PROTECTION Retaining wall 1 W/m and 0.5 microSv/h 1,5 M 0,6 m 5m Linac Tunnel PAUL GIOVANNONI date : 24/10/2014

  11. LINAC TUNNEL TECHNICAL OPTIONS (cont’d) LOS ALAMOS type option : linac tunnel buried deeply, ~ -8 m, and klystron building on top Advantages : - easy to connect and disconnect klystrons and pipes from klystron building to linac - need less surface than in other options because no earth material - constant earth compression of the tunnel Drawbacks : - water table must be deeper than in other options - HEBT, ring, RTBT and may be Front End building, buried deeply at the same level than the linac, so may be more expensive than in other options - schedule : impossible to build linactunnel and klystron building in parallel PAUL GIOVANNONI date : 24/10/2014

  12. LINAC TUNNEL TECHNICAL OPTIONS (cont’d) « No buried construction » option : linac tunnel on the floor and at the same ground level as klystron building Advantages : - water table less problematic - no trench Drawbacks : -more earth covering to shield linac tunnel but also HEBT, ring, RTBT -uneasy connection of wave guides and pipes from klystron to linac building Considered as unattractive PAUL GIOVANNONI date : 24/10/2014

  13. LINAC TUNNEL TECHNICAL OPTIONS (cont’d) Conclusion on the linac tunnel option LOS ALAMOS and « NOT BURIED LINAC »options are not retained CONCERT AND SNS OPTIONS : Lower cost for klystron building in case of CONCERT option but length of wave guides longer than in SNS option so we need to study in more details these two options in order to have a better estimate of the cost difference Construction and cost will depend on the characteristics of the underground. Extra costs resulting from deviations from the reference site to be added to the site premium (additional contribution from the host country) PAUL GIOVANNONI date : 24/10/2014

  14. LINAC TUNNEL TECHNICAL OPTIONS (cont’d) Chases connecting linac tunnel to klystron building We propose the same chase concept as that of SNS Klystron building Klystron building In these chases we find the following equipment : wave guides, chilled water pipes electrical cables Retaining wall Retaining wall 1.5 m Wave Wave guide guide 8 m 8 m 5 m 5 m Linac Linac tunnel tunnel Chase Chase These parts are fixed on a special support This support is put into the chase Inside a chase, wave guides are cooled down by chilled water pipes PAUL GIOVANNONI date : 24/10/2014

  15. Klystron wall Earth material Coupler Tunnel Cryomodule Q pole … KLYSTRON BUILDING : TECHNICAL OPTIONS Goal : minimize costs and therefore area Two constraints : 1)The short distance between couplers in the SC part (average : 2 m) - difficulty to put Klystrons side by side - high chaze density 2) The large size of the power supplies : 10 m x 8 m PAUL GIOVANNONI date : 24/10/2014

  16. PAUL GIOVANNONI date : 24/10/2014

  17. KLYSTRON BUILDING TECHNICAL OPTIONS (cont’d) option : - all equipment are in the klystron building ( RF, power supplies, cooling equipment, HVAC, electronics racks, diagnostics, vacuum control, quadrupole power supplies, etc ) • klystrons are in a vertical position, side by side -some mechanical equipment like HVAC, DI water system and rf power supplies are in alcoves. This results in a reduction of the building surface -metallic structure with double skin siding -utilization of air pads and fork lifts to move klystrons and other loads instead of travelling crane (to reduce the building height) PAUL GIOVANNONI date : 24/10/2014

  23. HVAC • Utilization of Air blast radiators to cool raw water • - Choice of the water pressure and the cooling temperatures values and their variations for process equipment • Local hvac or little plant for offices, laboratories, and test areas • Air conditioning units distributed along tunnels to keep right temperature when the beam is on • HVAC from FE an other parts to remove air in the tunnels before coming into (70 mn) PAUL GIOVANNONI date : 24/10/2014

  24. HVAC (cont’d) Temperature in the tunnels with beam : To Be Determined Temperature in the tunnels without beam after 70mn of ventilation : To Be Determined Temperatures in the FE : To Be Determined Temperatures in Klystron building : To Be Determined Temperature in the ring …. and other buildings : To Be Determined PAUL GIOVANNONI date : 24/10/2014

  25. BEAM DUMPS Linac beam dump : Passive or actif , depend on the power on the beam dump ? Injection beam dump : power on the beam dump ? Extraction beam dump : Passive or actif , depend on the power on the beam dump ? PAUL GIOVANNONI date : 24/10/2014

  30. MASTER PLAN Building implantation : CLO close Target buildings Advantages : easy access for users Guest house : one module of 60 rooms at the beginning of the operations, an other 60 rooms the third year and an other the seventh year Avantages : construction cost reduction COMPONENT ASSEMBLY  Technical option : RFQ , DTL, SDTL, CCL and SL will be assemble in the shop company, outside the site. These components will be installed and tested inside the Front End and Linac Tunnel. Justification :  To avoid buildings on the site for assembling components (cost reduction) and time reduction for the schedule. PAUL GIOVANNONI date : 24/10/2014
