5. Scope split • Scope includes service to technical water systems and electrical systems • G01/G02/G04 buildings • Support to other groups include: • Process systems support for neutron Instruments/Labs • Electrical support to Target • Everything outside of these areas are assumed to be handled by other groups, e.g. • Central processing plant is not included • HV switchgear is not included • HVAC and facility water systems are not included Scope split withconventionalfacilities - November 2016 ESS Operations Cost Review

6. Scope – Electrical • Accelerator racks • Disconnecting/connecting rack equipment • Maintenance • Low voltage switchgear • 3 electrical substations in G02 • Electrical substation in G04 (CRYO) • Electrical support to modulators, power supplies, etc. • Service to test stands & RF gallery in general • Cabling • Electrical connections Significantnumberof systems tosupport - November 2016 ESS Operations Cost Review

7. Scope - Water • Cooling water systems (pump skids and piping) in the front end building and tunnel (G01) • 2 skids for magnets, IS, LEBT, couplers, etc. • RFQ skid • DTL skid • Waste water handling • Local cooling system in G04 (CRYO) • Subsystem with pumps, heat exchangers, etc. • Cooling systems in G02 • RF gallery (valves, instrumentation, hoses) – 84 HBL RF stations, 36 MBL RF stations, 26 SPK RF station, 5+1 DTL/RFQ stations • Cold box room • Test stands (valves, instrumentation, skids) - Cryo test stand, RF test stand • 3 building process substations • Local water cooling systems for neutron instrumentsand labs • Skids (approx. 1 per instrument) • Utility panel (1 per instrument) • Bunker skids • Deionized water (make-up) for accelerator and instruments • Instrument air systems for accelerator and instruments/labs • Nitrogen gas systems for instruments/labs Significantnumberof systems to support - November 2016 ESS Operations Cost Review

8. Scope, Requirements and Function • Requirements • 95% availability • Maintenance & Services to other groups • Service to instrument scientists/engineers • Function • Maintenance • Leading on-going installations and minor upgrades • Connecting/disconnecting RF equipment Utility systems areimportant for ACC and NSS operation - November 2016 ESS Operations Cost Review

9. Labour Resources • Expertise requirements • Experience in operation and design of deionized water systems • Knowledge of instrumentation and controls of process systems • Experience in maintenance of process systems (process water, IA, nitrogen gas) • Experience of electrical systems in accelerator facilities • Staffing plan • Group leader • Electrical engineer • Cooling system engineer • 1 Electrical technician (licensedelectrician) • 2 Process water technicians (1 ACC + 1 NSS) Significantexperience in operation and maintenanceofutility systems required - November 2016 ESS Operations Cost Review

10. Comparison with Other Facilities Operation • In general difficult to benchmark with other facilities, due to differences in size and organization • Water: • SNS has 6 persons supporting accelerator cooling systems (manager, process system engineer, design engineer, 2 technicians, 2 research mechanics) • CERN has 8-10 persons, including technicians and contractors for the entire Meyrin site (cooling and ventilation) • Electrical: • SNS has 11 Technicians (system specific experts) and 14 Electrical Research Mechanics in the RF/Electrical group (supporting accelerator and target) Benchmarking shows thatnumberofstaff for utility systems should not be underestimated - November 2016 ESS Operations Cost Review

11. Operations Costs • Utilities group operations costs per year = 0.1 M€ • Valves, instrumentation, hose assemblies, gaskets • Cables, cable installation material • Tools • Consumables (welding, filters, grease, cleaning fluids, etc.) • Cost of external resources, incidents, overhauls • Does not include time for internal ESS resources such as designers (E&IS), procurement, programming of controls, etc. No major componentcostsbutshould not be understimated - November 2016 ESS Operations Cost Review

12. Summary & conclusions • Scope: • Process systems for ACC and Instruments/Labs • Conventional electrical systems for ACC + Target • Important support for operation and maintenance • In general difficult to benchmarkdue to organizational differences • Cost is mainly due to large incidents (pump failure, etc.) Summary - November 2016 ESS Operations Cost Review
