1 INTRODUCTION

The International Thermonuclear Experimental Reactor1 (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 the “Domestic Agency” (DA) of the European Union (EU), managed by the “Fusion for Energy2”, (F4E) 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 final design of the SSEN components was completed in July 2012. The bill of materials assignments to the US and EU have been decided and follow the intent of the ITER Agreement whereby the US provides 75% and the EU 25%. The Procurement Arrangement (PA) document, a covenant between the central ITER International Organization (IO) and the US DA with respect to the equipment it supplies, was signed in September 2012, permitting the US DA SSEN procurement activities to commence.

The US DA is overseen by the US Department of Energy which has assigned management responsibility to the US ITER Project Office3 (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 has issued a contract to the URS Corporation to provide Engineering Support Subcontractor (ESS) services related the specification, procurement, manufacturing oversight, and QC activities associated with the SSEN procurements.

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.

The USIPO WBS Manager is responsible for the procurement of the equipment as described herein:

2 BACKGROUND

ITER will receive AC power at 400kV, 50Hz from the French grid operator “Réseau de transport d’electricité” (RTE). A recent photograph of the new RTE substation called “Prionnet”, now energized, is given in Figure 1. The SSEN switchyard will be installed in the area immediately adjoining this substation.

US ITER 1040100-AD0002-R01

Figure 1 – ITER Construction Site Showing RTE Substation “Prionnet”

A one-line diagram of the SSEN in given in the attached reference drawing4, and a simplified version is shown in Figure 2.

The SSEN is subdivided into four power feeds. Two of the feeds consist of a 400kV substation transformer, 22kV distribution, and 6.6kV distribution. The other two consist of a 400kV substation transformer, 22kV distribution to load centers (LC), and 22kV distribution, which is transformed to 400V distribution for safety relevant (SR) and investment protection (IP) loads, which can also be energized using diesel generators (G). The 22kV bus bars can be interconnected as indicated under contingency situations to improve reliability of service. Where Figure 2 differs from the reference drawing, the latter shall take precedence.

All of the SSEN equipment will be built to IEC standards for 50Hz operation.

3 PROCUREMENT PLAN

As shown in Table 3-1 a total of sixteen (16) procurement groups have been identified based on the full list of items specified in the bill of materials (B/M) given Table 3-2. It is planned that each of the procurement groups will be procured via an individual contract to an individual supplier, although some bundling is possible.

PPPL will prepare, in conjunction with the ESS, purchasing specifications for each of the procurement actions listed in Table 3-1. 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 (http://www.fedbizopps.gov) web site. Related information is also available at the PPPL Procurement web site (http://procurement.pppl.gov/Procurement%20Opportunities.HTM). PPPL will follow US DOE Procedures in the bid evaluation and contract award process.

4 SCHEDULE

Although the ITER 1st plasma milestone is not scheduled until 2020, 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 2012.
