Shutdown/Startup Performance Improvements

• Tuning of process control system

• Tuning of valve actuators

• Sequencing of steam dump valves

• Procedural improvements

• Simulator and training improvements

• Manual reactor / turbine trip from low power 10

ALARA Performance

• Changes

- Step change in ALARA planning and scheduling

- Radiation Work Permit setpoint adjusted down to more effectively use dosimetry as ALARA tool

- Focused on radiation worker desired behavior prior to and during the outage

- PIP threshold changes 11

ALARA Performance (continued)

• Results

- Desired worker behavior demonstrated

- Desired increase of PIPs at lower threshold was obtained

- Comprehensive self-assessment of outage radiation practices - complete 12

2 EOC1 4 Refueling Outage

• Zero

• Zero

• Zero

• 32 dc LERs events injuries jys 13

Correct Component Verification (CCV)

• Defined specific behaviors associated with CCV

• Created a CCV flag

• Conducted classroom and flow loop scenario training

• Targeted observations with CCV focus

• 2EOC14 was completed without a CCV event

• Similar focus on CCV is now underway in operations and chemistry 14

Miscellaneous 15

Corrective Action Program PIP Significance Categories ACA No Cause Analysis 16

Corrective Action Program

• PIP Action Codes

- Corrective Actions to Prevent Recurrence (CAPR)

• Directed at the Root Cause of Category I and 2 PIPS

- Corrective Actions (CA)

• Directed at CAQ

- Elective / Enhancement Actions (ELEC)

- Structure helps focus corrective action effectiveness reviews on highest priority actions (CAPRs) 17

Special Nuclear Materials

• Completed comprehensive inventory

• No discrepancies 18

Security

m

• No concerns about schedule for compliance with NRC order.
