- Increasing safety significance
- Increasing NRC inspection efforts
- Increasing NRC/Licensee management involvement
- Increasing regulatory actions
Safety Significant Performance Indicator
- Unplanned Scrams with Complications
- Exceed green/white threshold (more than 1)
- Two scrams with complications
- Nov 9, 2012 - Shutdown required in response to a malfunction of the feed water control system.
- Dec 16, 2012 - Operator response to an automatic scram included reactor water level control challenges outside what is expected in a normal scram.
- Performance Indicator returned to Green during the 4th quarter of 2013.
Unit 2 - 95001 Supplemental Inspection Results
- Inspection completed in September 2013
- All inspection objectives were met
- Focus of the inspection was:

- December 19, 2012 (Loss of Feedwater)
- September 14 14, 2013 (Le (Level el Transient d during ring Planned Shutdown)
- Performance Indicator returned to Green during the 4th quarter of 2013.
Unit 2 - 95002 Supplemental Inspection - Objectives
- Provide assurance that the root and contributing causes off risk-significant i k i ifi t performance f iissues are understood.
- Independently assess the extent of condition and extent of cause.
- Independently determine if safety culture components caused or significantly contributed to the performance issues issues.
- Provide assurance that the licensees corrective actions are sufficient to address the root and contributing causes and prevent recurrence.
Unit 2 - 95002 Supplemental Inspection - Areas Covered
- Problem Identification
- Root Cause Evaluation
- Corrective Actions
- Independently Assess Extent of Condition
- Independently Assess Extent of Cause
- Safetyy Culture Assessment Inspection requirements that were common to the successfully completed 95001 inspection were not re-re inspected
Unit 2 - 95002 Supplemental Inspection - Dates and Team

- Independent review of Root Cause E l ti Evaluations
- Related issue review; Extent of Cause and Extent of Condition
Unit 2 - 95002 Supplemental Inspection - Focus
- Degraded Cornerstone for Initiating Events
- White Unplanned Scrams Per 7000 Critical Hours Performance Indicator
- Previously inspected scrams on November 9, 2012 and December 16, 2012
- Scrams on December 19, 2012 and September p 14,, 2013
Common Cause Assessment for Degraded Cornerstone
- 2 Root Causes
- Less Than Adequate Decision-making Related to Integrated Control System Design Scope (Single Point Vulnerabilities) and Operating Experience Reviews
- Less Than Adequate Management Reinforcement and Personal Accountability for Procedure Use and Adherence in O
Operations ti andd Engineering E i i D Departments t t
Common Cause Assessment Key Corrective Actions
