Safety Culture was appropriately considered Supplemental Inspection Results

18

• Corrective actions were comprehensive:

- Removed the backseat gaskets from the HP-426 valves and the SSF letdown line strainers

- Revisions to various procedures including the operability determination process, corrective action program, and SSF letdown line surveillances

- Developed a corporate Nuclear Safety Excellence Plan

- Performed an independent safety culture assessment Supplemental Inspection Results
