St Lucie Nuclear Reactor Unit 1 manually shutdown, 3 control rods drop into core

St. Lucie Nuclear Power Plant Unit 1 was manually shut down on August 13, 2026, after three control rods dropped into the reactor core while operating at full power. The NRC classified the event as non-emergency, and all plant systems responded normally, with the reactor successfully stabilized in hot standby mode. Unit 2 at the facility was unaffected.
