Princeton Plasma Physics Laboratory (PPPL), in partnership with Oak Ridge National Laboratory (ORNL), is fabricating the National Compact Stellarator Experiment (NCSX), a fusion energy research device that will be located at PPPL in Plainsboro, New Jersey. PPPL seeks expressions of interest, technical comments and budgetary estimates from firms interested in the fabrication of six (6) large poloidal field (PF) electromagnets for NCSX. As currently envisioned, two (2) each magnets of three (3) differing sizes and configurations (PF4, PF5 and PF6) will be required. The magnets will be wound in a conventional round geometry, pancake configuration, with close attention to stated tolerances and cleanliness of the fabrication environment. To simplify manufacture and reduce costs, all three coil types will use the same rectangular-cross section, hollow core copper conductor, glass taped and vacuum impregnated. The finished coils will vary in size from approximately 48.6 inches O.D. (PF4), to 178.9 inches O.D. (PF5), to 216.3 inches O.D. (PF6). The approximate finished weights of the coils are: 1,792.4 lbs. (PF4); 3,326.7 lbs. (PF5); and 1,883.0 lbs. (PF6). Preliminary drawings of all three coils are available for viewing and download at the PPPL Procurement Division web site, http://oorm-1.pppl.gov/public/procurement/. Currently, PPPL expects to release a request for proposals (RFP) for these coils in June 2007, with award of a firm fixed price (FFP) contract in August 2007 and delivery of all coils complete by December 2007. Firms interested in supplying this requirement are requested to provide written expressions of interest to PPPL. The response should include: complete contact information (firm name, address, representative name and telephone/fax/email); a statement of the firm?s experience in the manufacture of coils of similar size and configuration, including customer names and dates of delivery; a statement of the firm's ability to meet required tolerances and use required manufacturing procedures, and its ownership of, or access to, a suitable clean room assembly environment; comments (if any) concerning the adequacy and suitability of the preliminary drawings for fabrication; and a non-binding budgetary estimate of the cost to manufacture each coil. Responses may be sent by letter, fax or email to the address indicated below. This announcement is not a request for quotations or proposals, and firms will not be reimbursed for costs incurred to respond to this announcement.
