| Title | Notification of Unusual Event - Hurricane Warning |
| Event Description | At time 1700 [EDT] today, the National Weather Service issued a Hurricane Warning for the area including the St. Lucie Nuclear Power Plant. On that basis, a Notice of Unusual Event was declared at time 1714 [EDT]. In anticipation of severe weather, the site has completed proceduralized high wind preparations.
Both units are currently stable at 100% power. The licensee notified both State and local agencies and has informed the NRC Resident Inspector. No safety-related systems are out of service. The electrical grid is stable. Notified DHS SWO, FEMA Operations Center, DHS NICC, FEMA NWC (email), DHS Nuclear SSA (email), and FEMA NRCC SASC (email).
At 1701 [EDT] today (09/09/17), a 24-hour update was made to state and local governments following the National Weather Service issuing yesterday's hurricane warning for the area including St. Lucie Plant. On that basis, a Notice of Unusual Event was declared yesterday (09/08/17) at 1714 [EDT]. There are no changes in plant status for either Unit. In anticipation of severe weather, the site previously completed high wind preparations. Our plants have been specifically built to withstand natural disasters such as hurricanes, tornadoes, earthquakes, flooding and tidal surges. This approach will ensure the safety of operations and our employees and the communities surrounding our plants. Both units are currently stable at 100% power level and will remain at that power since hurricane force winds are not currently projected to reach St. Lucie Plant. The NRC Resident Inspector has been informed. Notified R2DO (Michel).
