Project Baseline - Contingency• The amount of contingency established at the beginning of the project was based on a risk
assessment performed as part of the cost estimating process. • Total cost contingency included 3 elements:
• 1) a task-by-task subjective contingency assessment for unknowns and uncertainties; • 2) a weighted assessment of tabulated risk events (Appendix E of closeout report) • 3) schedule contingency applied to accommodate potential project stretch-out (a.k.a.
“standing army” cost).

Project Baseline – Schedule MilestonesProject scope and KPP’s were completed August 10th, 2015 approx 1 1/2 months ahead of schedule.
(1) Acceleration result of NSTX operations being curtailed due to an inner TF coil failure. The start of the outage ahead of CD-3 was approved by DOE (ECP-004) and consisted of hardware removal tasks only.
(2) Original baseline date was June 2014 but its slippage was anticipated therefore the milestone date was rescheduled by one month as documented in ECP-114.
(3) This had been planned to be a stand-alone subcontract. The scope for this work was actually added to the overall Inner TF machining subcontract which was award to Major-Tool and Machine in August 2011.
(4) Initial ISTP completed in April 2015 however during an attempt at a 100% power shot, just prior to a first plasma attempt , an OH coil arc fault occurred which resulted in an extensive internal and external investigation process as well as hardware repairs. Subsequent to hardware repairs being made and reconciliation of a root cause analysis findings the PPPL executive ES&H committee approved ISTP testing to resume. The successful ISTP testing led to a first plasma being achieved on August 10, 2015

Lessons Learned
Aqua pour event
• “Aquapour”, used during fabrication to maintain a thermal expansion gap between the center stack TF & OH winding.
•Beneficial in winding the CS OH conductor, however, we were not able to remove the aqua pour as planned due to it being impregnated with epoxy.
•Resulted in a critical path schedule delay and will impose additional operational requirements.
•Event was postulated in the risk registry
•Could have exercised additional engineering due diligence to better understand the failure mechanisms
•R&D simulations performed but did not subject the process to the epoxy impregnation step.
•Next Time:
1. Better think through technical, fabrication and assembly risk.
2. Be more mindful of experience and familiarity morphing into overconfidence.
3. Consider incorporating a failure modes and effects analysis as part of our fabrication and assembly planning.
Opportunity #1
NSTX-UNSTX-U NSTX Upgrade Project – Office of Science Review – September 2nd, 2015 91
Lessons Learned
Better balance in assigning CAM's to scope
•The centerstack design and fabrication was assigned to one CAM who was the laboratory's expert in coil manufacturing.
•The CAM who quickly became overloaded.
•Oversights in procurement inspections, timely reconciliation of cooling wave analysis, more complete field supervision, support of EVMS CAM duties,
•Created a bottleneck in fabrication tooling which required a lot of attention.
•Additional support on engineering the tooling might have save rework.
•Schedule Impacted
•We tended to focus on the near critical path and big ticket procurements or those that are technically challenging. While this helped us to successfully navigate the 6 largest risks on the project (i.e. Vacuum Pressure Impregnation (VPI) of the centerstack) this led to smaller procurements of hardware to receive less attention until it came time for assembly. Some of these components had to be re-worked by PPPL to meet specification which led to internal schedule delays and diversion of critical staff (i.e. welders, machinists).
•Next time: 1.Ensure CAM’s are not overloaded and adequate staff are assigned for oversight and supervision. 2.Ensure PPPL QC has adequate resources to support the receipt inspection process.
Opportunity #2
NSTX-UNSTX-U NSTX Upgrade Project – Office of Science Review – September 2nd, 2015 92
Lessons Learned
Procurement
•We were reminded to “trust but verify” our new vendors especially before awarding multiple procurements.
•There were some components that required welding of pieces that were pre-beveled (a.k.a. weld prepped).
•We did not require a hold inspection on these components and the vendor proceeded to weld the joints without pre-inspection.
•Once the hardware was received and inspected by PPPL, we discovered that the material welded had not been properly prepared. PPPL had to grind away and re-weld questionable joints.
•Next time:
1.Ensure fabrication inspection hold points,
2.timely receipt inspections, and
3.Better vetting of our vendors.
Opportunity #3

NSTX-UNSTX-U NSTX Upgrade Project – Office of Science Review – September 2nd, 2015 93
Lessons Learned
Loss of Key Personnel
•Loss of our DCPS CAM (due to his sudden death) as well as the temporary loss of the Magnet CAM (due to lengthy illness) resulted in impacts to the project schedule as other stepped up to “fill-in”.
•A secondary impact was an increase in project cost as lesser experience personnel took longer to come up to speed and carry on the work.
•Next time:
1.Cost and schedule risks for loss of key personnel must be more thoroughly analyzed and quantified.
Opportunity #4

3.Clarify process for identifying SME’s ( subject matter experts)
4.Ensure robust training and adherence to conduct of operation policies and procedures for machine start-ups
Opportunity #5
NSTX-UNSTX-U NSTX Upgrade Project – Office of Science Review – September 2nd, 2015 95
Lessons Learned
Safety•The attention to worker safety resulted in only 5 minor reportable minor injuries in over 573,000 hours worked.
•While we have a robust safety organization and up front Management buy-in, it came down to people not taking risks or short cuts in the name of schedule or cost.
•The safety culture at PPPL is one of its strongest assets
Successes #1
NSTX-UNSTX-U NSTX Upgrade Project – Office of Science Review – September 2nd, 2015 96
Lessons Learned
Supervision•Work control center provided real value in establishing daily communication and coordination of field activities.
•Field support needs (QC weld inspections, Safety support for walk downs, Health Physics) were determined in a daily 10 minute meeting.
•This process was established during the TFTR D&D project which was successful in finishing safely on schedule and $3.6M under budget.
Successes #2
NSTX-UNSTX-U NSTX Upgrade Project – Office of Science Review – September 2nd, 2015 97
Lessons Learned
Technical Risk•The project was not risk adverse on employing new processes or technologies. The project utilized 7 fabrication and assembly techniques that benefited the construction of the new center stack magnet and vessel upgrade; (Ref Appendix K for detailed descriptions)
• Friction stir welding of copper was used to join high strength to high conductivity copper grades in the TF center bundle conductors.
• A new non-ionic soldering process was developed.
• Wire Electric Discharge Machining (EDM) was used in the manufacture of the critical TF High-Current Connector.
• A carefully planned Vacuum Pressure Impregnation (VPI) process with hard metal molds were used to assure the strength and electrical integrity of the center stack.
• Cyanate Ester / Epoxy Resin was chosen because of its maintenance of strength at elevated temperature.
• Electron Beam Welding was used to manufacture the TF Lead Extensions and Passive Plate expansion connectors.
• A water-soluble casting material, “Aquapour”, was used to maintain a thermal expansion gap between the center stack TF and OH winding. This process proved beneficial in winding the CS OH conductor, however, we were not able to remove the aqua pour as planned due to it being impregnated with epoxy. See Opportunity #1
