A -- FABRICATION OF PROTOTYPE SUPERCONDUCTING CABLE FOR THE TOKAMAK PHYSICS EXPERIMENT (TPX) POC John Tennyson (510) 423-2383 The University of California, Lawrence Livermore National Laboratory (LLNL), seeks sources for the fabrication of Nb3Sn superconducting cables for use in prototype toroidal field (TF) and poloidal field (PF) coils for the Tokamak Physics Experiment (TPX). These cables will be supplied to an as-yet undesignated firm for encapsulation in Incoloy-908 conduits. The resulting Cable-in-Conduit Conductors (CICC) will be supplied to a Magnet Subcontractor for tooling checkout and prototype coil production. In order to be considered responsive to the RFP, prospective sources will be required to provide or have provided proof of ability to produce strand to the TPX specification, including test data as well as material on which confirmatory tests can be carried out. Prospective sources should have personnel experienced in the fabrication of superconductor strand and cable. Subject to the availability of funding, LLNL intends to issue an RFP approximately April 15, 1995 time frame for TF prototype cable to firms responding with an expression of interest. TPX is designated as a national fusion initiative by the U.S. Department of Energy (DoE). Hence, cost-sharing arrangements and participation by the international community are not being sought. Appropriate evaluation, consideration, and preference will be given to U. S. industry in accordance with the provisions of the Buy American Act. Submit your Expression of Interest to Mr. John Tennyson by March 15, 1995. The total length of prototype TF cable required is approximately 1.3 km, with an estimated mass of 3.2 tonnes. The total length of prototype PF cable required is approximately 0.8 km with an estimated mass of 0.7 tonnes. Facsimile and telephone responses will not be accepted. This notice is to assist the University in determining the potential for competition; no solicitation is currently available. (0040)
