| Title | Offsite Notification |
| Event Description | The following information was provided by the licensee via email:
At 1530 [EDT] on 7/11/2023, North Anna Power Station notified the Virginia Department of Environmental Quality (DEQ) that a small volume of filtered/purified water potentially discharged into Lake Anna from a leak from a reverse osmosis unit. The leak did not follow the normal release path for discharge through outfall 013. No environmental impact associated with this leak was observed or would be expected because the water in question is cleaner than the lake water, and would have met all discharge requirements for outfall 013. The NRC Resident Inspector was notified. This event is reportable in accordance with 10 CFR 50.72(b)(2)(xi). |
