Outage Per ormance

* Personnel Exposure- Excellent crudburst

- Significantly improved radworker practices- Dose reduction techniques obtaining results

* Record dose in last refueling on each unit- U1= 70.4 Rem

- U2= 91 Rem- U3= 108 Rem (est)

* 1999 Station dose lowest ever - 202 Rem

Outage Performance* Human Performance

- Lower tier schedules

- Operations expectations

- Rework

- Control of non-assigned individuals

- Individual initiative and ownership

- Supervisory involvement

Areas of Continued Focus

* Operational Focus

* Human Performance

* Equipment Reliability

* Outage Performance

10 eeNce Equipment Reliability

* Ongoing initiatives- Equipment aging program

- Engineering rapid response team

- INPO assist visit

- Trip/transient prevention

Equipment ReliabilityTrip/Transient Reduction

* Review all previous ONS trips (complete)

* Review all B&W Owners Grouprecommendations (complete)

* Identify critical system functions (complete)- Perform walkdowns (complete)

- Review monitoring programs (ongoing)

- Review PM programs (complete)

- Identify single failure vulnerabilities (complete)

Equipment Reliability

Trip/Transient Reduction

Examples of team recommendations- Delete unnecessary secondary side auto trips,

such as CBP low suction pressure trip- Upgrade NLO rounds

- Correct material condition problems identifiedin walkdowns

- Add redundancy to single failure points, suchas stator coolant temp & pressure

Equipment Reliability

* Measures:- Lost generation due to equipment failure

- Lost generation events

- %0 Effectiveness in meeting M-Rule Al actionplans

- M-Rule functional failures

- System & component health reports
