  1. U.S. ITER Project STEADY STATE ELECTRIC POWER NETWORK(SSEPN) Charles Neumeyer SSEPN Team Leader Princeton Plasma Physics Laboratory 1st Information Forum Vendor Fair November 15, 2006

  2. 400kV Steady State Electric Power Network Pulsed Electric Power Network Host (EU) 120MW 50MVAR 130MVA Continuous EU + US ~ Class IV: CWS 37MW Cryo 27MW Other 50MW Class III (Safety): 8MW 500MW 400MVAR 650MVA Pulsed EU + China ~ ~ P,Q Control = = Heating & Current Drive Magnets ITER AC Power Systems

  3. 400kV Steady State Electric Power Network Pulsed Electric Power Network Host (EU) 120MW 50MVAR 130MVA Continuous EU + US ~ Class IV: CWS 37MW Cryo 27MW Other 50MW Class III (Safety): 8MW 500MW 400MVAR 650MVA Pulsed EU + China ~ ~ P,Q Control = = Heating & Current Drive Magnets ITER AC Power Systems Similar to auxiliary electrical system of nuclear power plant except higher power level

  4. Status of SSEPN Activities • Conceptual design was developed for a generic site in 2001 • Conceptual design was updated in 2004 • Decisions on site selection and scope sharing made in 2005 • Preliminary design activity based on French site now beginning

  5. SSEPN Roles of US & EU

  6. ITER AC Power Systems: One Line Diagram Grid Operator SSEPN PEPN

  7. SSEPN One Line Diagram

  8. SSEPN Equipment HV Switchgear HV Transformers MV Switchgear MV Cabling Diesel Generators MV Transformers LV Load Centers LV Distribution Boards LV Cabling

  9. Equipment Split by US (75%) & EU (25%) HV Switchgear HV Transformers MV Switchgear MV Transformers LV Load Centers LV Distribution Boards

  10. 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 • - 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 1E like a fission plant) • Equipment to be delivered to ITER site in France HV Switchgear HV Transformers MV Switchgear MV Transformers LV Load Centers LV Distribution Boards

  11. Participants and Roles within US Activity • Administration • Liaison w/International Team • Monitor Engineering Design Activities • Oversight of E/C contract • Oversight of Procurements • Engineering • 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 • Fabrication & Delivery US ITER Project Subcontract to Engineering/ Construction Firm Equipment Manufacturers

  12. Schedule = activity involving US • 12 months for procurement • 18 months for fabrication • 24 months for installation • 12 months for commissioning

  13. 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

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