3 1 INTRODUCTION The International Thermonuclear Experimental Reactor 1 (ITER) is a project now underway in France to construct a device that will demonstrate nuclear fusion power at a powerplant-relevant scale. The international partners, including the US, are each responsible for contributions of resources and equipment to the project. In the area of AC power distribution, two subsystems are defined, namely the Steady State Electrical Network (SSEN) providing power to the conventional plant loads, and the Pulse Power Electrical Network (PPEN) proving power to the pulsed experimental loads. The design of both the SSEN and PPEN is being developed by Empresarios Agrupados, a Spanish engineering company, which is part of an industrial consortium called ENGAGE 3 under contract with the Domestic Agency (DA) of the European Union (EU), managed by the Fusion for Energy, (FE) organization. The EU DA is also responsible for the emergency diesel generator power system, most of the power cabling, and the installation of the entire AC distribution system. The remaining SSEN materials and supplies are to be contributed by the DAs of the United States (US) and the EU and the PPEN materials and supplies by China (CN). The exact division of scope in terms of SSEN equipment to be supplied by the US and EU was recently decided and follows the intent of the ITER Agreement whereby the US provides 75% and the EU 5%. Once the Final Design Review is completed (Spring 01) and the Bill of Materials finalized, the details of the contribution of each DA will be specified in a Procurement Arrangement (PA) document (Summer 01) which will delineate all technical and procedural requirements. This PA will serve as a covenant between the central ITER International Organization (IO) and each DA with respect to the equipment it supplies US ITER AD000-R00 Page 3

4 The US DA is overseen by the US Department of Energy which has assigned management responsibility to the US ITER Project Office 5 (USIPO) hosted by the Oak Ridge National Laboratory (ORNL). The work scope associated with the SSEN is assigned to the Princeton Plasma Physics Laboratory (PPPL) and is led by its Work Breakdown Structure (WBS) manager who is responsible for the work described herein. PPPL will issue a contract to an Engineering Support Subcontractor (ESS) to provide assistance in the specification, procurement, manufacturing oversight, and QC activities associated with the SSEN procurements. This contract will be awarded in advance of the PA issuance so that the process can begin as soon as possible. The PPPL Procurement Division will issue solicitations, lead the evaluation of offers, negotiate with selected suppliers, and place and administer all contracts for the purchase of the subject equipment. The ESS will assist in this process. The ITER IO will utilize a Global Transport and Logistics Service (GTLS) for transport of all equipment from the manufacturers facilities to the final destination. The US DA will engage and pay for the GLTS services for shipping and related items such as insurance, tariffs, etc., for each shipment. Once the PA is issued the process of procurement, manufacturing, and delivery is planned to commence immediately. The USIPO WBS Manager is responsible for the procurement of the equipment as described herein: Mr. Charles Neumeyer Princeton University, Plasma Physics Laboratory P.O.

5 BACKGROUND ITER will receive AC power at 00kV, 50Hz from the French grid operator Réseau de transport d electricité (RTE). A recent photograph of the installation of the new RTE substation called Prionnet, now underway, is given in Figure 1.

6 A one-line diagram of the SSEN in given in the attached reference drawing 6, and a simplified version is shown in Figure. PLEASE NOTE THAT THE REFERENCE DRAWING IS PRELIMINARY AND IS SUBJECT TO CHANGE. The SSEN is subdivided into four power feeds. Two of the feeds consist of a 00kV substation transformer, kv distribution, and 6.6kV distribution. The other two consist of a 00kV substation transformer, kv distribution to load centers (LC), and kv distribution, which is transformed to 00V distribution for safety relevant (SR) and investment protection (IP) loads, which can also be energized using diesel generators (G). The kv bus bars can be interconnected as indicated under contingency situations to improve reliability of service. Where Figure differs from the reference drawing, the latter shall take precedence. Figure - Steady State Electrical Network (SSEN) All of the SSEN equipment will be built to IEC standards for 50Hz operation. 6 ITER Drawing entitled ONE-LINE GENERAL SSEN, filename SSEN_One_Line_Preliminary.pdf US ITER AD000-R00 Page 6

7 3 PROCUREMENT PLAN Recently it was determined, based on a common EU/US cost basis, that the US obligation to supply 75% of the equipment contribution would best be met by supplying components of the system covered by the procurement packages listed in Table 1. A bill of material for the equipment assigned to the US is given in the appendix. PLEASE NOTE THAT THE BILL OF MATERIAL IS PRELIMINARY AND IS SUBJECT TO CHANGE Table 1 List of Procurement Packages Package Name HV Circuit Breakers HV Switches HV Surge Arresters HV Current Transformers HV Potential Transformers HV Control & Protection HV Substation Hardware HV Substation Transformers kv Switchgear Power Transformers 6.6kV Switchgear Reactive Power Compensators UPS DC Distribution LV Distribution & Sub-distribution Panels US ITER AD000-R00 Page 7

8 PPPL will prepare, in conjunction with the ESS, purchasing specifications for each of the procurement actions listed in Table 1, in the approximate order listed. Each procurement action will be initiated by the issuance of a Pre-Solicitation Notice, followed by a Request for Proposal. Both of these notices will be issued on the Federal Business Opportunities ( web site. Related information is also available at the PPPL Procurement web site ( PPPL will follow US DOE Procedures in the bid evaluation and contract award process. SCHEDULE Although the ITER 1 st plasma milestone is not scheduled until 00, parts of the SSEN are needed much earlier to support the need for site power as the construction, installation, and commissioning activities progress. For this reason the US plans to issue Request for Proposals (RFP) for all of the procurement actions during calendar year 01, beginning as soon as possible following the issuance of the PA document.
