2. Topics • Outage Planning • Outage Coordination • Installation Risks and Mitigations • Outage Progress in 2013 • Remaining Structural Work • Work Once Centerstack is in NSTX Test Cell • Tasks to Prepare for Return to Operations

3. Outage Planning • Outage planning based on bottoms-up estimates from Engineering • Assumes just 5 days per week for almost all tasks • Assigns technicians, by name, to critical scope to assure staffing requirements are met • Adjust start dates of tasks to assure tasks in the same area are compatible • Accelerate tasks that make other tasks safer or more efficient • Work crews on opposite sides of vacuum vessel or on different shifts • Daily / hourly coordination of all field work is critical

4. Outage Coordination • Use of Work Control Center (like TFTR D&D Project) to oversee and coordinate all activities in the NSTX Test Cell • All work in the NSTX Test Cell being done with Engneering Work Packages (EWPs) • Work Control Center reviews all EWPs for the field • Reviews removal/installation procedures • Reviews Job Hazard Analysis (JHA) • Attends pre-job and post-job briefs • Interfaces between Engineering and the field crews • Assures that the field work is done safely and correctly • Assures the field crews are used efficiently

5. Outage Coordination • Daily Plan-of-the-day meetings to coordinate activities between crews and fine tune technician assignments • Includes field crew leaders, QA, Safety, Health Physics, Industrial Hygiene, DOE • Adjustments based on actual progress and manpower availability • Flexibility for adjustments comes from • Second shift work • Multiple crews working on opposite sides of the vessel • Having many work packages ready for field work • Safety and efficiency from • Temporary platforms to improve efficiency • Trial fit-ups to verify handling techniques and minimize time spent on NSTX • Temporary platforms to improve access and safety (inspected every shift) • Plan work so crews are on opposite sides of machine

6. Installation Risks and Mitigations • Delays in getting parts delivered to installation crews • Re-schedule work sequence • Schedule work on two shifts once parts arrive • Scope creep • Engineering Change Proposal process • Review of engineering estimates by division heads (WAF review) • Fit-up of new centerstack • Estimate includes three fit-ups

7. Outage Progress in 2013 • Install new umbrella legs / feet / slides • Install umbrella arch reinforcements

8. Outage Progress in 2013 • Install reinforcements for TF to umbrella interface

9. Outage Progress in 2013 • Replace PF2/3 clamp hardware and install additional PF2 clamps • Install new PF4/5 supports and replace existing hardware (still in progress)

10. Outage Progress in 2013 • Modify vacuum vessel legs to clear new TF turnbuckles

11. Outage Progress in 2013 • Move two TF outer legs to new locations (to make room for other work) • Install two new TF outer legs to replace ones taken out of service

12. Outage Progress in 2013 • Re-silverplated leads on TF outer legs

13. Outage Progress in 2013 • Installed new cable tray around top of machine • Walking surface included in top of tray

14. Outage Progress in 2013 • Installed most of the TF outer leg upper support structure • Successfully proven out this very challenging installation procedure

15. Remaining Structural Work • Finish installing new PF4/5 supports and replace existing columns • Install new TF outer leg lower supports • Install new centerstack pedestal • Install TF outer support turnbuckles • Add extensions and anchors to vacuum vessel leg struts

16. Work Once Centerstack is in NSTX Test Cell • Lift centerstack casing over the OH/TF bundle • Install PF1A upper coil • Install kapton/G10 flash shields • Lift centerstack into vacuum vessel • Install TF flex bus support rings • Install ceramic break assemblies • Install organ pipes • Install instrumentation cables to centerstack • Install CHI flags • Install edge tiles in-vessel

17. Work Once Centerstack is in NSTX Test Cell • Install bus inside umbrella and back to racks • Install new TF flex bus • Field measure space between centerstack and all TF flags • Fabricate 72 unique centerstack to TF flag links • Install umbrella lid support rings • Install new umbrella lids

18. Tasks to Prepare for Return to Operations • Clean, photo and close the vacuum vessel • Pumpdown • Leak check • Bakeout All routine tasks at the end of an outage

19. Summary • The Upgrade Outage has been planned based on • Bottoms-up estimates from Engineering • Identifying staff to do the work • Scheduling work to avoid conflicts • The plan is being continually worked • To improve safety and efficiency • To deal with delays in getting parts • To accelerate tasks to make full use of resources • Coordination and Control • Provided by the Work Control Center • At the Plan-of-the-day meeting • Continuously by the Field Supervisors • Successfully performing the outage (SPI= 0.97, CPI= 1.09) • Will turn over NSTX to Operations in a fully ready condition
