WBN2 Annual Estimates 2008 $s Average Net Megawatts = 1180 MWe Non-Outage O&M Fixed O&M Estimate Basis Incremental Staffing 330 Using WBN staffing study.

Compared against delta between SQN two-unit and WBN1 one unit long-term staffing targets.

Cost of staffing $35.3M Includes Overheads/Benefits

($107/yr SQN & WBN avg.)

Materials & O&M Projects $4M 3 year average delta from SQN Other Contract Services $4M 3 year average delta from SQN Insurance/NEI/INPO Fees $1.1M NEI/INPO approx $.64 M NRC Fees $4.7M Annual Fee = $4.24M per unit Inspection Fee = $500k increase Total Fixed O&M $49.1M Outage O&M Variable O&M Annual outage cost $18.0 $27M per outage every 18 mos.

Capital Annual capital $15.3M Based on $13M per 1000 MW Total O&M and Capital Annual 1-Unit Total $82.4M

Other Costs Decommissioning $5.45M Based on a 5% real ROR over 40 years. ($374M PV cost)

INPO Assessment Point Value $238,000. Formula is 3 points for each site and 1 point for each unit. Incremental cost for WBN2 is just 1 point times the point value.

NEI fee is $316.13 per gross megawatt.

= 1270 X 316.33

= $401,000.

2007 NRC Annual Reactor Fee is $4,237k per unit.

Inspection fee is based on number of hours times an hourly rate. FY 05 Actual:

FY 2006 FY2007 BFN $890,000 SQN $1,347,000 $960,000 WBN 1$1,312,000 $1,678,000 Net increase for second unit is relatively low. Assume $500k per year.

O&M Projects assumed to average $1.5M per unit.

WBN long term Staffing Plan target is 441 and SQN long term target is 807.

Difference is 366 multiplied by $107.00/person fully loaded is $39.1 million.

No staffing or budget increase was assumed for WBN2 security. Sites are increasing security staffing due to regulatory changes (i.e. 10CFR26, fatigue rule, etc). However, WBN1 would have needed to make the increase with or without WBN2 completion.

Fuel cost: $126 million allocated for the WBN2 initial core.
