Inspection Conclusions"* Inspection procedures are more objective
and risk-informed
"* Scope of inspections not much different but outcomes are more risk-informed
"* Less licensee time spent responding to low value issues (Level IV violations)
"* Dialogue between licensee and NRC focused on safety
..EI::::!'..
Summary of Observations
"* Combination of PIs and Inspection Findings able to discern performance differences
"* Findings in Corrective Action area correlate with Action Matrix results
"* Findings in Human Performance DO NOT correlate with Action Matrix results
