Description

Princeton Plasma Physics Laboratory (PPPL), in partnership with Oak Ridge National Laboratory (ORNL), is developing a new class of experimental fusion research devices known as compact stellarators. Potential manufacturers are currently being sought for two of the key components of a new device, the NCSX (National Compact Stellarator Experiment): the electromagnets (modular stellarator coils) and the vacuum vessel. As currently envisioned, all of the magnets are wound of flexible compacted copper cable. They are cooled by gas at liquid nitrogen temperatures flowing through chill plates bonded to the windings. The windings are supported by highly shaped, machined stainless steel castings. A typical overall magnet envelope is 80in x 80 in x 40 in.; each completed magnet will weigh approximately 3000 lbs. There are four distinct geometric magnet types (ie, geometric shapes). A total of 21 magnets are required. The vacuum vessel is a highly shaped toroidal shell manufactured of Inconel 625 (or equivalent) 0.375" thick. The vessel shape has a periodicity of three and will be manufactured in 3 sections with bolted flanges. Press forming, explosive forming, or casting are potential manufacturing methods. The vessel has multiple ports and flanges that are also part of this assembly. The assembled vessel has an average major diameter of approximately 120 inches, an average minor diameter of 45 inches, and weighs about 12000 lbs. An information meeting is planned for Wednesday, August 22, 2001, at PPPL, located on US Rt. 1 in Princeton, NJ. (For travel directions, see http://www.pppl.gov/about_pppl/pages/visiting_pppl.html.) Details of these components will be discussed and questions will be answered. Contracts for manufacturing studies will be placed early in CY 01. Contracts for prototypes are anticipated in CY 02. The actual component manufacture is scheduled to begin in CY 03. In addition to the NCSX components described above, a similar set of modular coils will be required by a second compact stellarator, the Quasi-Poloidal Stellarator, QPS, to be built at ORNL on approximately the same schedule. Additional technical information is available at the NCSX web site, located at http://www.pppl.gov/me/NCSX_MFG/. This information is also available on request on CD-ROMs. For registration and further information, please send an email request to ppplproc@pppl.gov, or call R. Templon at 609-243-2443.
