Enclosure 2 Arkansas Nuclear One Presentation Meeting Summary of the 6/8/2010 Meeting with NRC/SNC/FPL/SCE&G Dated June 17, 2010
Discussion of Screening Criteria Arkansas Nuclear One (ANO)
Jessica Walker ANO Fire Protection
Overview
- NRC Working Group Results
- Arkansas Nuclear One (ANO) Review
Arkansas Nuclear One (ANO)
Background Information
- 2001 Triennial Fire Protection Inspection - Resulted in White Finding
- Failure to ensure that cables and equipment of redundant trains of systems necessary to achieve and maintain hot shutdown conditions would remain free of fire damage (in the event of a fire)
- Fire Areas 98J and 99M in Arkansas Nuclear One, Unit 1 (ANO-1)
- ANO initiated a Manual Action Review Project to identify potential changes to plant systems and components in order to reduce the complexity of safe shutdown manual actions
Arkansas Nuclear One (ANO)
Background Information
- June 30, 2004 - Entergy Operations, Inc. (Entergy) provided the results of the ANO, Units 1 and 2 10CFR50, Appendix R Manual Action Review Project
- December 17, 2004 - Entergy provided the schedule for completion of modifications and analyses to eliminate the time critical complex manual actions at ANO, Units 1 and 2
- March 31, 2005 - NRC closed the White Finding based on the results of Supplemental Inspection 50-313/05-11; 50-368/05-11
- November 2, 2005 - Entergy submitted a letter of intent to adopt NFPA 805
Arkansas Nuclear One (ANO)
Background Information
- Current state of Fire Protection at AND
- Modifications completed to eliminate time-critical, complex recovery actions
- Revised Operations Fire Procedures
- Prescriptive response to notification of a severe fire
- Non-Compliances addressed since white finding
- Tracked in the corrective action process
- NFPA 805 Project Plans
- Coordinating with Pilot Plant transition activities
- Participating in NEI NFPA 805 Task Force activities
Screening Criteria
- NRC Working Group Results
- Potential issues with protection or separation for safe shutdown equipment
- Relatively large number of Operator Manual Actions (OMAs)
- Limited documentation of cable routing
- Use of complex OMAs
- Symptom-based fire response procedures with complex OMAs
Potential Issues with Protection or Separation
Relatively Large Number of Operator Manual Actions
- Risk analysis
- Realistic Fire Modeling
- Modifications
Cable Routing Documentation
- Since construction, cable routing data has been maintained electronically
- ANO cable routing data was initially turned over electronically from the Bechtel Circuit and Raceway schedule after construction
- Electronic Databases have been in use since the 1980's containing the cable to raceway and raceway to fire zone relationships
- The Plant Data Management System (PDMS) is the current repository for the safe shutdown equipment list and the relationship of equipment to safe shutdown cables
- PDMS provides for configuration control of cable and raceway data by tracking changes from design through as-built configuration
- A high level of confidence in the accuracy and integrity of data is provided by PDMS
Use of Complex Operator Manual Actions
- June 13, 2007 - Entergy provided the results of the completed modification and analysis to eliminate the time critical complex manual actions
- One modification was eliminated by the risk evaluations associated with the transition to NFPA 805
- The analyses and modifications to eliminate the other identified manual actions statused as complete
- These modifications reduce overall fire risk
- In addition, AND has a safe shutdown review process that reviews modifications and procedure changes to ensure ongoing control of the required manual actions
OMA Elimination Examples
- U1 OMA - Manual action to re-close 8512 load center breaker in 98-J and 99-M
- To restore offsite power at LC bus 85 without the need to take operator actions, the breaker 8512 control cables, specifically cables RC8512C and RCD 11 09A that were re-routed
OMA Elimination Examples
- U-2 OMA: Eliminate action to de-energize and close sump recirculation header isolation valve 2CV-5649-1
- Potential existed for a "hot short" to cause 2CV-5649-1 to spuriously open
- A spurious open signal to the Refueling Water Tank (RWT) outlet valves had potential to drain the RWT to the containment sump
- The "hot short" issue was resolved by replacing the "hot" conductor with a new cable routed in new conduit between cabinets Control Room
Complex Critical Operator Manual Actions - Unit 1 Type (Check one)
One Time Action Continuing Scheduled Completion Date Commitment Compliance (If Required)
Zone 98-J: Eliminate action to manua lly re-close 8512 X Complete load center breaker Zone 98-J: Eliminate action to de-energize and close X Complete pressurizer ERV isolation valve Zone 98-J: Eliminate actions to establish emergency X Complete diesel power Zone 99-M: Eliminate action to manually re-close X Complete B512 load center breaker Zone 99-M: Eliminate actions to establish emergency X Complete diesel power Zone 1DO-N: Eliminate actions to establish emergency X Complete diesel power Zone 112-1: Eliminate action to de-energize and close X Complete pressurizer ERV isolation valve

Symptom Based Fire Response Procedures
- Safe shutdown procedures have evolved since the identification of the original white finding
- Since 2004, safe shutdown procedures are prescriptive upon notification of a severe fire
Screening Criteria Conclusions
- AND Screening Results Only two screening criteria apply
- Potential issues with protection or separation for safe shutdown equipment
- Relatively large number of OMAs Three screening criteria do not apply
- Limited documentation of cable routing
- A high level of confidence in the accuracy and integrity of data is provided by PDMS
- Analyses and modifications to eliminate identified complex, critical manual actions complete
- Symptom-based fire response procedures with complex OMAs
- Safe shutdown procedures are prescriptive upon notification of a severe fire
