Baseline Inspection Preparation and Documentation (BIPD) Trends Steve Campbell Amar Patel Sarah Obadina
Industry Comments Data Analysis Determine whether industry claims were accurate During the RIC, industry provided a comment that we should continue to look for efficiencies with inspection They specifically cited reducing inspection hours and indicated an increasing trend in baseline inspection prep/doc hours
BIPD Definition in Cost Activity Code (CAC) system Time spent preparing for baseline inspections including:
Inspection plan development Information requests Licensee discussions Review information in preparation for performing assigned inspection activities Research Attending a briefing from resident inspectors Badging / site access, including obtaining dosimetry and whole-body count Entrance/exit meetings Time spent documenting inspection results including:
Writing inspection reports Review of report inputs Reviewing reports for final signature Certifying reports and troubleshooting Reviewing RPS data to ensure accuracy of information for associated inspection report
Process
- Cost Activity Codes (000473)
- Collected data for 2019-2023
- Included decommissioned sites (while operating) and sites under construction
- Indian Point, Three-Mile Island, Oyster Creek, Duane Arnold, Palisades, Vogtle 3&4, Pilgrim
- Data Analysis
- All inspections

Focused Engineering Team Inspections (FEI)
- Summary
- Overall downward trend over the last five years
- Region 3 had a slight increase in BIPD
- Examples: Equipment Qualification (EQ), Power Operated Valve (POV), Commercial Grade Dedication (CGD), Age-Related Degradation (ARD),
Fire Inspections
- Data was normalized by the number of inspections per year
Overall conclusions
- Overall trend for BIPD was decreasing
- However, in certain instances, depending on the specific inspection or region, the trend was increasing or relatively flat
- Downward trend for BIPD for most of the Team inspections
- IMCs/IPs do not provide criteria for charging BIPD
- CAC Definition
- Inspection plan development, information requests, entrance/exit meetings, etc
Areas for follow-up CAC review for consistency of definitions Self-assessment review of the use of BIPD Review Guidance
