Coordination Meeting - Diagnostic Systems (WBS 3)

A coordination meeting was held on October 18 with Dave Johnson, Wayne Reiersen, and Bob Siummons.  Three topics were discussed:

Reiersen provided a revised WBS Dictionary.  The revised WBS for Diagnostic Systems is posted here.

The revised WBS also reflects the new guidance that everything required at or before the start of initial ohmic operations (Phase 3) should be part of the construction project.  Johnson indicated that this would represent a significant up tick in the cost of WBS 3, in the range of 1-2M$.

Bob Simmons noted that we should not be using the words Total Project Cost or TPC.  Rather, we should be using the words Construction Project Cost.

The work plan for WBS 3 leading up to the CDR consists of the following steps:

1. Define the initial and full complement of diagnostics in the General Requirements.  The initial complement of diagnostics should be coordinated with the Initial Experimental Research Plan (a controlled document to be produced prior to the CDR by Zarnstorff). [Due by 11/21, Action:Johnson]
2. Determine the incremental cost associated with the new guidance of what should be included in the construction project cost. [Due by 12/21, Action:Johnson]
3. Integrate the diagnostics with the design of the stellarator core.  This is an ORNL-led activity (Cole) with support from Johnson defining technical requirements. [Due by 1/31, Action:Cole]
4. Complete conceptual design of diagnostics.  Focus on diagnostics in construction project.  Prepare plausibility argument that other diagnostics required as future upgrades could be accommodated. Identify interfaces with other systems - make sure everything is accounted for (but not designed) and all parties understand where the interface is. [Due by 2/15, Action:Johnson]
5. Develop cost and schedule inputs for Bob Simmons. [Due by 3/1, Action:Johnson]
6. Develop system description for inclusion in CDR documentation. [Due by 3/15, Action:Johnson]
7. Prepare presentation for CDR. [Due by 3/29, Action:Johnson]

Preliminary resource allocations for this scope of work are as follows:

One issue that did come up had to do with who was responsible for the field cabling between Diagnostics Systems (WBS 3) and Central I&C (WBS 5).  Johnson advocated making Ramakrishnan (Power Systems, WBS 4) responsible for the work because that was who did that work on NSTX.  Reiersen agreed to follow-up on this issue with Ramakrishnan and Oliaro in upcoming coordination meetings.
