Subject Matter Experience in Cooling systems and Electrical systems • Anton Lundmark (Technical Water Systems): 9 years of process engineering experience and engineering project management – – – • WP manager “accelerator and NSS technical cooling systems” at ESS 2014 -2016 Project engineer “warm piping and storage tanks for cryogenic systems” at ESS 2015 -2016 Engineering group manager for about 20 people at AREVA 2013 -2014 Process engineer (and partly project manager/coordinator) at AREVA 2007 -20013 Operation, service & maintenance experience as electrician (mainly heavy industry projects), approx. 2 years in total Frithiof Jensen (Technical Electrical Systems): 29 years experience in power electronics, electrical engineering, telecom service and operations, management systems. – – 3/9/2021 Operation and Management, JET Joint Undertaking, AH Power Supplies Group. 1988 – 1997 Industrial Hardware Development, RADAR Systems, TERMA A/S. 1997 – 2000 Telecom Software, Service Provisioning and Datacenters, Ericsson Telebit A/S. 2000 – 2007 Systems Operations and Management (Data Centers, Web Services), Mobile. Think A/S. 2009 – 2011 Significant experience in utilities operation- November 2016 ESS Operations Cost Review 4

Scope split • Scope includes service to technical water systems and electrical systems – G 01/G 02/G 04 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 3/9/2021 Scope split with conventional facilities - November 2016 ESS Operations Cost Review 5

Scope – Electrical • Accelerator racks – Disconnecting/connecting rack equipment – Maintenance • Low voltage switchgear – 3 electrical substations in G 02 – Electrical substation in G 04 (CRYO) • Electrical support to modulators, power supplies, etc. • Service to test stands & RF gallery in general – Cabling – Electrical connections 3/9/2021 Significant number of systems to support - November 2016 ESS Operations Cost Review 6

Scope - Water • Cooling water systems (pump skids and piping) in the front end building and tunnel (G 01) – – • Local cooling system in G 04 (CRYO) – • – – – 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 instruments and labs – – – • • • Subsystem with pumps, heat exchangers, etc. Cooling systems in G 02 – • 2 skids for magnets, IS, LEBT, couplers, etc. RFQ skid DTL skid Waste water handling 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 3/9/2021 Significant number of systems to support - November 2016 ESS Operations Cost Review 7

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 3/9/2021 Utility systems are important for ACC and NSS operation November 2016 ESS Operations Cost Review 8

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 – – – 3/9/2021 Group leader Electrical engineer Cooling system engineer 1 Electrical technician (licensed electrician) 2 Process water technicians (1 ACC + 1 NSS) Significant experience in operation and maintenance of utility systems required - November 2016 ESS Operations Cost Review 9

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) 3/9/2021 Benchmarking shows that number of staff for utility systems should not be underestimated - November 2016 ESS Operations Cost Review 10

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. 3/9/2021 No major component costs but should not be understimated November 2016 ESS Operations Cost Review 11

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 benchmark due to organizational differences • Cost is mainly due to large incidents (pump failure, etc. ) 3/9/2021 Summary - November 2016 ESS Operations Cost Review 12
