Inspection Trends
- Increase in the number of Notices of Nonconformances against Criterion III, Design Control"
- Some inspections resulted in no findings
- Continue to observe issues with:
- adequate implementation of commercial-grade dedication programs
- adequate qualification of safety-related suppliers and sub-suppliers
- adequate implementation of corrective action programs 4
SONGS Lessons Learned
- Evaluate lessons learned in the area of vendor oversight
- 2 recommendations identified:
- Perform pilot design-related inspections at vendor facilities prior to and/or during the fabrication process for safety-related major plant modifications
- Develop identification guidelines and screening criteria to determine:
- When a plant change can be considered a major plant modification
- When a major plant modification should be subject to a vendor inspection
- 1st pilot design related aspect inspection at Equipos Nucleares, S.A (ENSA) in Santander, Spain
- At least 1 other planned 5
SONGS Lessons Learned
- Conclusions
- No specific findings identified related to issues in the design review, design change process, design documentation, or design related software at ENSA
- Continue to perform design-related inspections as part of the pilot program
- Assessment will determine if design related aspect inspections continue on a permanent basis 6
