- 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 Baseline Inspection Procedures Slide 3 of 5
ALARA Considerations Persistent downward trend in collective radiation exposure (CRE) 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 Average Measurable Dose per Individual
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
