50.72 Proposed Rule:
Reporting Requirements for Nonemergency Events at Nuclear Power Plants Alexa Sieracki, Rulemaking Project Manager Regulatory Analysis and Rulemaking Branch, Division of Rulemaking, Environmental and Financial Support, Office of Nuclear Material Safety and Safeguards
Background and Status
- In the 1980s, NRC adopted requirements in 10 CFR 50.72(b) for licensees to immediately notify NRC of potentially significant nonemergency events.
- In 2018, NEI submitted petition requesting removal of the 10 CFR 50.72(b) requirements.
- In 2021, the Commission directed NRC staff to pursue rulemaking with following restrictions:
- Do not shift responsibility for gathering, verifying, and communicating information on these events from licensees to resident inspectors
- Discontinue rulemaking if not cost-justified or if changes would unacceptably degrade NRCs situational awareness.
Background and Status
- NRC staff published a regulatory basis on November 9, 2022 containing an analysis of whether reporting requirements can be modified or eliminated when they do not have a commensurate safety benefit.
- The regulatory basis concluded that 6 of the notifications could be eliminated and 2 would benefit from updated guidance.
- The regulatory basis also concluded that licensees could use an alternative reporting method for submitting nonemergency event notifications.
- NRC staff are currently working on drafted the proposed rule
- Proposed rule due to the Commission: May 2024
- Public meeting will be held during public comment period
- Public comment period after Commission approval
- Final rule to the Commission: February 2026
