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

Unit 1 at the Saint Lucie Nuclear Power Plant was manually shut down on August 13, 2026, after three control rods unexpectedly dropped into the reactor core while the unit was operating at 100% power. The Nuclear Regulatory Commission classified the event as a non-emergency, and the plant reported that all systems responded normally. The reactor was stabilized in Hot Standby mode, with decay heat being removed via the main condenser. Unit 2 was unaffected.
