| Title | Turbine Trip Causes Automatic Reactor Scram at Oyster Creek |
| Event Description | The licensee reported that an automatic reactor scram occurred at 0259 due to a turbine generator trip from a hi-hi moisture separator water level. One control rod indicated position 02; however, the remainder of the control rods indicated full in. All other systems and components functioned as designed. The licensee is cooling the plant down to cold shutdown.
The licensee notified the NRC Resident Inspector. |
