1 QPS Project Implementation Presented by B. Nelson for the QPS team QPS Conceptual Design Review June 23-24, 2003 ORNL

2 Presentation Outline Fabrication Plans How we plan to build QPS R&D, primarily Modular Coils Benefits of NCSX work QPS Schedule Overall schedule QPS schedule by major component QPS Cost Methodology Estimates Contingency June 23-24, 2003 QPS CDR - Project Implementation 2

3 Fabrication Plans and Options Most components built off-site and pre-assembled to the extent possible System In-Vessel Components - Divertor plates, limiters Vacuum Vessel Conventional Coils - TF, PF, Centerstack assy Modular Coils Structures -connecting structures, base columns Coil Services - electrical leads, cooling Assembly, incl. mod coil field period sub-assy Fabrication By: Fabricated off-site or in house Commercial Tank manufacturer - PF coils exist, refurbish on site - Centerstack, TF similar to NSTX, (but integration by vendor) - Winding forms by NCSX vendor - Winding, VPI, canning by Univ. TN Commercial manf, same as VV if possible Commercial leads, piping on site Assembly on-site by ORNL craft June 23-24, 2003 QPS CDR - Project Implementation 3

4 Modular Coil Fabrication Modular Coils are very similar to NCSX, but not the same: Cast-and-machined winding form Flexible cable conductor Canned for vacuum compatibility Vacuum pressure impregnated with epoxy Winding forms will be manufactured by same vendor as NCSX winding forms, if possible, and procured by PPPL Winding, canning, and VPI to be done by University of Tennessee June 23-24, 2003 QPS CDR - Project Implementation 4

5 We plan to build the coils at UT Less costly: Lower net labor costs (direct+indirect) (~ 50%) Space is available at no charge More flexible arrangement with respect to contract/design changes since UT is a partner in the QPS project Relatively close proximity to ORNL design team Strengthens UT / ORNL interaction Provides thesis topics, fusion interest for graduate students June 23-24, 2003 QPS CDR - Project Implementation 5

6 Organization for modular coil tasks at UT Separate organization set up within the Mechanical Engineering Department under Department Chair (Tom Shannon) Full time engineering manager will report to Tom Shannon Technicians hired as temporary employees by UT Graduate students will assist where appropriate QPS design team at ORNL will be responsible for design, and assist with technical oversight. Space will be prepared in the recently completed Science and Engineering Research Facility (SERF) 3 adjacent rooms envisioned, 24 x 32 ft each Elevators, loading dock, hallways, etc. are adequate for receiving and moving modular coils All processes to be developed through R&D June 23-24, 2003 QPS CDR - Project Implementation 6

One winding line planned, but space should accommodate two winding lines Process flows from winding to canning to VPI Dimensional and electrical inspection occurs continuously

7 One winding line planned, but space should accommodate two winding lines Process flows from winding to canning to VPI Dimensional and electrical inspection occurs continuously 24 ft 32 ft No autoclave is needed since coils will already be vacuumcanned Winding line #1 Winding line #2 canning TBD VPI June 23-24, 2003 QPS CDR - Project Implementation 7

8 Rolling cart fixture avoids handling issues Winding form shipped from vendor on cart, stays on cart for all winding, canning, VPI processing and shipping to ORNL 4 ft 10 ft Top View 8 ft Side View End View 10 ft June 23-24, 2003 QPS CDR - Project Implementation 8

9 R&D will be needed for modular coils R&D will be integrated with NCSX project Modular coil winding forms will be very similar, but no poloidal break Modular coil conductor and windings will be very similar Vacuum impregnation will be similar, but will not require cocoon Continue involvement of University of Tennessee as well as potential vendors for coil winding forms Draft specification and models for winding forms will be developed to obtain input from industry June 23-24, 2003 QPS CDR - Project Implementation 9
