"During the scheduled shutdown to commence the Peach Bottom Unit 3 refueling outage, Unit 3 was manually shutdown using the mode switch in accordance with GP-3, 'Normal Plant Shutdown,' when reactor period lowered below 50 seconds as indicated on the WRNM [Wide Range Nuclear Monitoring] system. The Feedwater Startup Level Controller was in automatic set at 23" when a small addition of cold water added enough positive reactivity to cause reactor period to be less than 50 seconds. The shortest period observed was 44 seconds. The WRNM system RPS [Reactor Protective System] automatic SCRAM setpoint is 19 seconds."
All control rods inserted into the core. Decay heat is being removed by shutdown cooling. The plant is continuing into its scheduled refueling outage.

"On September 14, 2009, Progress Energy Environmental Services determined that approximately 200 deceased or stressed Ladyfish (Elops saurus) were observed near the banks of the Crystal River Energy Complex (CREC) discharge canal. Only Ladyfish were found stressed or deceased. Three of the stressed fish were sampled and examined by the CREC Mariculture Center to evaluate potential causes of these fish mortalities. Of the three fish examined, the only item of note was that the stomach and intestinal tracks were empty. It is likely that the runoff from recent heavy precipitation, coupled with summertime warm water temperatures and rapid salinity changes, resulted in a localized area of low dissolved oxygen and physiologic stress that affected this population of Ladyfish. There were no unusual conditions or factors associated with CREC operations that would have contributed to this event. Notification to the Florida Fish and Wildlife Conservation Commission will be made. This is reportable per 10CFR50.72(b)(2)(xi) as an event for which notification to other government agencies will be made."
