Auxiliary Feedwater/Instrument Feedwater/Instrument Air Red Inspection Finding (Cont)

Cont)

  • Determined to not be an Old Design Issue
  • April 2, 2003 - Final Determination:

Red Issue

  • April 2003 Agency Action Review Meeting - Decision to perform IP 95003 inspection at Point Beach 12

Point Beach Auxiliary Feedwater/

Feedwater/Recirculation Line Orifice Plugging Issue

  • October 29, 2002 - Second Potential Common Mode Failure of Auxiliary Feedwater Pumps identified during routine system test
  • Failure Mechanism - Plugging of the recirculation line flow orifices
  • Inadequate Corrective Actions for first Auxiliary Feedwater issue contributed to the significance of the second issue 13

Auxiliary Feedwater/

Feedwater/Recirculation Line Orifice Plugging Issue (Cont)

Cont)

  • December 11, 2003 - Final Significance Determination: Unit 1 - Yellow Issue; Unit 2 - Red Issue 14

Inspection Procedure (IP) 95003 Supplemental Inspection for Repetitive Degraded Cornerstones, Multiple Degraded Cornerstones, Multiple Yellows, or One Red Finding Input.

Intent: Provide the NRC with supplemental information regarding licensee performance, as necessary to determine the breadth and depth of safety, organizational, and programmatic issues.

15

IP 95003 Inspection Objectives

1) Provide insights into overall causes of Performance Deficiencies
2) Evaluate Programs and Processes
3) Evaluate licensee ability to identify, evaluate, and correct problems
4) Extent of Risk Significant Issues
5) Provide NRC recommendation for further Regulatory Action 16

IP 95003

  • More diagnostic than baseline procedures
  • Includes reviews of programs and processes not reviewed during baseline
  • Reviews aspects of strategic performance areas that are known to be a problem as well as those aspects that are not known to be problems
  • Results of the 95003 used in deciding what additional actions should be taken 17

The Point Beach 95003

  • Three Phases
1) Corrective Action Team (CAT)
2) Emergency Preparedness Team (EPT)
3) Engineering, Operations, and Maintenance Team (EOMT) 18

Corrective Actions Team (CAT)
