ROP Radiation Safety ALARA Oversight Recommendations Slide 1 of 5

Radiation Safety Cornerstones Slide 2 of 5

Baseline Inspection Procedures IP Number Title (%PRS/%ORS)* Nominal Hours Inspection Samples 71124 Radiation Safety-Public Occupational N/A N/A 71124.01 Radiological Hazard Assessment and Exposure Controls (0%/100%) 36 +/- 4 (annual) 10-16 71124.02 Occupational ALARA Planning and Controls (0%/100%)** 46 +/- 14 (biennial) 9-15 71124.03 In-Plant Airborne Radioactivity Control and Mitigation (0%/100%) 16 +/- 4 (biennial) 4-6 71124.04 Occupational Dose Assessment (0%/100%) 20 +/- 4 (biennial) 4-8 71124.05 Radiation Monitoring Instrumentation (33%/67%) 32 +/- 4 (biennial) 17-28 71124.06 Radioactive Gaseous and Liquid Effluent Treatment (100%/0%) 35 +/- 4 (triennial) 9-16 71124.07 Radiological Environmental Monitoring Program (100%/0%) 29 +/- 4 (triennial) 3 71124.08 Radioactive Solid Waste Processing and Radioactive Material 34 +/- 4 (biennial) 8-15 Handling, Storage and Transportation (80%/20%)

• PRS = Public Radiation Safety Cornerstone; ORS = Occupational Radiation Safety Cornerstone

• • Staff has proposed retiring this procedure (with transfer of some of its contents) as part of the ROP Enhancement effort Slide 3 of 5

ALARA Considerations

• Persistent downward trend in collective radiation exposure (CRE) Average Measurable Dose per Individual per reactor

• CRE is used to facilitate risk-informed oversight

- A measure of the challenges a program faces

- Dose limits apply to individual doses not collective doses

• Industry performance as reflected through a combination of inspection outcomes and CRE

• Staff position that baseline inspections in the ALARA area can be reduced from a risk-informed, performance-based perspective Slide 4 of 5

ALARA Inspections - Proposal Pending Commission approval (SECY-19-0067)

• ALARA planning and controls remains an inspectable area per IMC 0308

• Proposal to retire focused baseline inspection procedure

- Focuses finite inspection resources in a risk-informed manner

- Leverages other inspection efforts for performance-based inspection of ALARA

• Proposed approach will emphasize performance

- Observations of radiation workers

- Evaluation of licensee planning associated with significant radiological work

- Evaluation of licensee assessments of discrepancies between planned and actual doses Slide 5 of 5
