## NSTX FACILITY OPERATED ~ 90% AVAILABILITY

- • High operational availability (~90%) maintained while ramping up the facility and diagnostic capability (and sophistication.)
- • While the TF joint failure was an unfortunate event, the newly designed TF joint should significantly improve operational reliability needed to achieve the five year plan - 21 run weeks per year.
- • Total FY 00-03 run weeks achieved 48 weeks compared with the planned 54 weeks.
- • ISM (Integrated Safety Management) culture emphasized; N.J. Governor’s safety awards in 2001 and 2002.
- • Cost of a spare OH solenoid budgeted in FY 04-05.

|  | FY 00 | FY 01 | FY 02 | FY 03 | FY 04 - 08 |
| --- | --- | --- | --- | --- | --- |
| Run weeks planned | 15 | 15 | 12 | 12 | 21 |
| Run weeks achieved | 15 | ~16 | 13 | 4 |  |
| Hours of operations | 600 | 640 | 520 | 160 | 840 |
| Average shots/week | 104 | 116 | 118 | 80 |  |

**Notes:**
Listed here in black are diagnostics we currently have operating.
Red indicates a diagnostic which is being installed or upgraded this summer.
In green are diagnostics planned for installation in the next couple of years.
If I have time, I will try to tell you about developments in those areas which are underlined in this table.

## BUDGET ESTIMATE ASSUMPTIONS 

- • 21 weeks per year operations estimated are based on past operational experiences.
- • The proposed 5 year budget is  ~ 10 % above the FY 04 presidential level for both PPPL and collaborators; relatively flat for future years.
- • Upgrade cost is estimated bottom-up where possible, with contingency based on experience.
- • Avoided strong front loading of upgrades:
- 	- implementations timed to match the program plan.
- 	- consistent with personnel availability

- We made some tough choices.

## The NSTX 5-Year Plan is an Exciting and Cost-Effective Element of the U.S. Fusion Energy Science Program

_**Quality and Relevance are High**_
- Research facility and integrated national research team are both world class
- Forefront scientific results and innovative plans in all key areas:
- Stability, Transport, Startup and Sustainment, Boundary, Integrated Scenarios
- Plans are directly aligned with FESAC IPPA goals
- Collaboration across a broad frontier:
- ICC’s, Tokamaks, Astrophysics, Fusion Technology
- Contributes to ITPA
- Providing scientific basis for attractive CTF and Demo
_**Facility Operation and Upgrades are Cost Effective**_
- Three NJ Governor’s Safety Awards
- 90% availability, average of 112 shots per operational week since FY 01
- Thorough plan to fix TF joints and avoid future losses of run time
- Innovative facility and diagnostic upgrades support each area of research
- PPPL NSTX upgrade costs average 10.5% of total budget over five year period
- Total proposed yearly budget about 10% above FY2004 President’s request
