Significant budget gap between 5 year plan and FWP budget guidance needs to be resolved

5 Year Plan Budget Plan:• 21 weeks per year operations.

• ~ 10 % above the overall FY 04 presidential level for both PPPL and collaborators; relatively flat for future years.

• Key upgrade investment of ~ 12% of total budget.

FWP Base Budget Plan:• FY 04 Presidential budget allowed 21 run weeks and key upgrades.

• Assumed flat $ at the FY 04 presidential level for FY 05 and FY 06.

• However, effective reduction of ~ $0.9 M for FY 05 and ~ $1.8 M FY 06 due to

inflation.

• Latest information: Due to the congressional rescission, OFES has given a

guidance of $500k reduction from NSTX operations with reduction of three run

weeks from 21 to 18.
