- Susquehanna Unit 2
- Licensee Response Column
- All Green Findings and Performance Indicators
Safety Significant Findings or PIs
- White finding
- July 16, 2010, internal flooding event in the Unit 1 condenser bay. Inadequate procedures led to the event and complicated operator response 11 p
p p
leading to a loss of the normal heat sink.
- Crossed the Green-to-White threshold during the first quarter 2011. (i.e., >3 unplanned scrams)
Substantive Cross-Cutting Issues
- Problem Identification and Resolution-Evaluation (P.1 (c) - Evaluation/Extent of Condition)
- Theme identified during 2010 End of Cycle Theme identified during 2010 End of Cycle
- SCCI opened during the 2011 Mid Cycle
- Maintained open during the 2011 End of Cycle based upon PPL not meeting established exit criteria
- There were 5 findings with this aspect in 2011 as well as the 2010 White Finding 12
Substantive Cross-Cutting Issues
- Human Performance (H.2(c) -
Documentation and Procedures)
- Theme identified during the 2011 Mid C
l A
t Cycle Assessment
- Opened during the 2011 End of Cycle
- There were four findings in 2011 with this cross cutting aspect.
13
Cross-Cutting Theme
- Human Performance (H.4(a) - Human Performance Error Prevention Techniques)
- Theme identified in 2011 End of Cycle
- In 2011, there were 5 findings in this area.
14
Traditional Enforcement Follow-up
- The NRC will conduct a IP 92723, Follow Up Inspection for Three or More Severity Level IV Traditional Enforcement Violations in the Same Area in a 12-Month Period 15
January 1 - December 31, 2011 Unit 1 continued in the Degraded Cornerstone Colum of the Action Matrix SCCIs assigned for Problem Identification and Resolution - Evaluation (P.1(c)), and Human Susquehanna Annual Assessment Summary 16 Performance - Procedure Adequacy (H.2(c))
Cross-cutting theme identified in the Human Performance Human Error Prevention Techniques (H.4(a))
Multiple Traditional Enforcement violations impacting the regulatory process, results in an IP 92723 inspection
