Modular Coil Development Articles (Reiersen) |
|
Summary |
A telecon was held between ORNL
(Nelson) and PPPL (Schmidt, Strykowsky, Neilson, Chrzanowski, Simmons, and Reiersen) to
discuss the modular coil development activities reflected in the proposed
ECP5 baseline. Design verification and schedule reasonableness were
the focus of discussion. Reiersen prepared a handout (see above) that
served as the basis for discussion along with the proposed ECP5 baseline
that Strykowsky had prepared earlier.
In reviewing the plans, it was noted that no activities or resources had been identified for the testing of the planar racetrack coil. Also, no test plans beyond the standard acceptance testing that would ordinarily be performed as part of acceptance testing, were provided for the prototype modular coil. (Action: Nelson to resolve testing issues re the planar racetrack coil and prototype modular coil. ) A logic and schedule for design reviews was proposed and consensus was reached that it represented a reasonable path forward. The review schedule, organized by test article, is discussed in the following paragraphs. The logic and dates are to be incorporated into the ECP5 baseline. (Action: Strykowsky to modify ECP5 baseline accordingly.) Twisted racetrack coil (TRC). An FDR would be held to cover the winding assembly of the TRC, which is supposed to be prototypic of the production coils in every way. It would address the clamps, chill plates, other custom hardware, and local I&C. The FDR needs to be held prior to procurement or fabrication of the constituent components. The design of the chill plates is lagging. It was decided to slip the fabrication of the TRC (and its FDR) about a month to address this schedule problem. This would still allow the the winding of the TRC to be completed prior to winding the Prototype Modular Coil (PMC). The date proposed for the TRC FDR is 02 April. An MIT/QA plan is required prior to the start of fabrication. A Fabrication Readiness Review (FRR) was proposed and accepted for the TRC. Its main focus would be the the MIT/QA plan and the safety controls to be used during coil winding. The FRR would be held prior to the start of winding the TRC, around 15 April. A Coil Winding Facility Operations Plan (CWFOP) that provides a high level description of the operations, quality assurance and safety controls would be drafted for the FRR and finalized prior to the MCWF FDR in May. (Action: Chrzanowski to draft the CWFOP.) Prototype Modular Coil (PMC). Design verification for the PMC would be patterned after the reviews planned for the TRC. An FDR would be held prior to procuring or fabricating the chill plates and other custom hardware (and hardware whose design had changed as a result of TRC fabrication) around 19 April. In addition, a FRR for the PMC would be conducted prior to the start of winding, around 07 July. Type C Production Modular Coils. Design verification for the Type C coils would be patterned after the reviews planned for the TRC and PMC. An FDR would be held prior to procuring or fabricating the chill plates and other custom hardware (and hardware whose design had changed as a result of PMC fabrication) around 15 November. In addition, a FRR would be conducted after completion of the PMC and prior to the start of winding the first production article, around 15 December. Type A and B Production Modular Coils. FDRs and FRRs for the first of each of these production articles would be scheduled for 2005. |
