Summary of NCSX System Integration Team (SIT)
Meeting of Monday, March 8, 2004
1. Mitigating Final
Design Review Schedule Risks
- A good plan is in place to
prepare for the FDR. Additional resources have been brought in. The schedule
is fixed. The only free parameter available to control schedule risks is
scope. We need to keep working to identify the minimum scope of the
review, and be sure the essential preparation tasks and deliverables are
clearly defined and being worked.
- A comprehensive list of
pre-FDR peer reviews and FDR deliverables was presented by Brad at the 2/23
SIT meeting. There is a consensus that the list needs to be pared.
Responsibility: Wayne to lead in identifying the crucial peer reviews
and indispensable deliverables.
- It was argued that a
Winding Pack configuration peer review and wrapping up the Port Configuration
peer review have high priority. The latter is planned for Friday morning,
March 12. Responsibility: Brad.
2. Resource Requirements
vs. Availability
- We are underspending at
both PPPL and ORNL this FY and need to identify the labor resources needed to
expedite critical tasks and, if possible, pull work forward from future years.
The following were discussed:
- Electrical design
(designers)
- Coil winding R&D,
tooling, etc. (Chrzanowski to identify needs)
- Vacuum vessel joint
R&D. (Viola to identify; anticipate needing machinists and
welders)
- Fabricating modular coil
hardware, e.g. clamps, chill plates. (Chrzanowski to
identify)
- Brad stated that an
additional design engineer has recently come on board at
ORNL.
3. FDR Preparation
Schedule
- The following schedule was
adopted:
- March 21,
Commit to review dates and start recruiting the reviewers.
- May 10, Post all
review documentation that the reviewers need to review in advance.
- May 11-13, Dry Runs
- May 14,
Presentations to Pamela to post.
- May 14,
Teleconferences with the MCWF and VVSA subcommittees (see what
questions they have).
- May 19-20, FDR at
PPPL.
4. Critical Issues
Update
- Good progress has been made
recently in resolving the critical issues. Category I issues (problem but
no plan) are moving to Category II (problem being addressed) and III
(problem resolved). The latest critical issues list is
at
http://ncsx.pppl.gov/NCSX_Engineering/Management/Critical%20Issues/CriticalIssuesStatus.xls.
- Conductor deformation
issues: recent tests found keystoning greater than expected. Coil twists
and bends may distort the winding pack due to previously underappreciated
geometrical effects. It may be necessary to change the conductor
dimensions again. This is an issue for the winding pack configuration peer
review.
- Port adapters. It was
decided that, as a rule, ports will have a first flange just outside the
modular coil shell, for maximum flexibility. A stainless steel port adapter
with the same cross section shape will extend from the first flange to outside
the cryostat. The port adapters are the responsibility of WBS 12, but
are not expected to be included in the VVSA contract. Diagnostics (WBS 3) and
other users are responsible for identifying exceptions or special
requirements.
- Coil test facility:
operations may be over-constrained by the NSTX operating schedule.
Action: Hutch to discuss with
Gettelfinger.
5. Project Finances
Highlights
- Draft ECP-5 proposes to
reduce contingency by $600k, to $15.3M, less than 25% of work remaining.
- Project is underspending in
FY04. A substantial increase in spending in the remainder of the FY will be
necessary to spend out. Flexibility is limited due to caps on
discretionary spending at PPPL. Project is working to identify
labor-intensive tasks and available labor resources. Actions: Hutch arrange
meeting with Mike Williams and Rich Hawryluk to address NCSX resource needs at
PPPL. Wayne identify any needs not currently captured in FY04 WAFs.
Brad work the issue at ORNL.
- Management reserve stands
at $2.2M.
6. Overdue document
approvals
- Delinquents are reminded to
sign the documents requiring their approval.
7. Next SIT Meeting:
Monday, March 15, 2004 at 11:00 a.m.
