Equipment Procurement • It is anticipated (but not yet agreed) that: - cost estimate will be updated after preliminary design completion - groups of equipment will be assigned to US and EU for 75: 25 split HV Switchgear HV Transformers MV Switchgear MV Transformers LV Load Centers LV Distribution Boards - credit for US-EU inbalance amount will be agreed to • Equipment will be built to IEC standards for installation in France • Special requirements for nuclear installation not anticipated TBD (i. e. not Class 1 E like a fission plant) • Equipment to be delivered to ITER site in France Steady State Electric Power Network 10 PPPL

Participants and Roles within US Activity • Administration US ITER Project - Liaison w/International Team - Monitor Engineering Design Activities - Oversight of E/C contract - Oversight of Procurements • Engineering Subcontract to Engineering/ Construction Firm - E/C Contract to: § prepare procurement specifications § solicit bids § perform bid evaluation § make purchase recommendation § award and execute contracts § provide QC and test witnessing at factories § arrange shipping § provide QC receipt inspection at ITER site • Procurement Equipment Manufacturers • Fabrication & Delivery Steady State Electric Power Network PPPL

Schedule = activity involving US ü 12 months for procurement ü 18 months for fabrication ü 24 months for installation ü 12 months for commissioning Steady State Electric Power Network PPPL

Summary • SSEPN is a conventional AC power substation & distribution system • US will procure 75% of equipment (except cables, D/G, and UPS) • Work will flow through an E/C firm to equipment manufacturers • Equipment will be per IEC standards for delivery and installation in France • Procurement/fabrication phase over 30 month period beginning 2010 Steady State Electric Power Network 13 PPPL

Opportunities for Participation • More information about design, etc. , is available via C. Neumeyer • Close contact with industry is sought to facilitate planning & budgeting!! Steady State Electric Power Network 14 PPPL
