At 1849 hrs, Surry Power Station (SPS) Uni … At 1849 hrs, Surry Power Station (SPS) Unit 1 and Unit 2 experienced an automatic Reactor Trip from a Loss of Offsite Power, as a result of a tornado touching down in the station's switchyard. Unit 1 reactor tripped as a result of a Loss of Coolant Flow > P-8 (35% power), and the Unit 2 reactor tripped as a result of a 500 kV Leads Differential Turbine-Generator trip. Both units responded as designed. </br>Unit 1 electrical power is being provided by Number 1 Emergency Diesel Generator (EDG) to the 1H emergency bus, with the Station Blackout (SBO) diesel loaded on to the 1J emergency bus. Unit 2 electrical power is being supplied by the number 2 EDG to the 2H emergency bus, with the number 3 EDG loaded on to the 2J emergency bus. </br>All Unit 1 control rods inserted on the reactor trip, and all Unit 2 control rods inserted on its respective reactor trip. The Low Level Intake Structure (LLIS) is without power. All three Emergency Service Water Pumps are running to supply the intake canal. Efforts are underway to restore Bus 7, which will give each unit an emergency bus powered by offsite power (Unit 1 1J, Unit 2 2H) and restore power to the LLIS. </br>Decay heat is being removed by auxiliary feedwater on both units and atmospheric steam release via the steam generator PORVs. Both units are currently on natural circulation. All other system parameters are normal and stable. </br>At 1855 hrs a NOUE was declared due to a loss of offsite power (applicable to U1 and U2). Additionally, due to an estimated 100 gallon fuel oil spill from an above ground storage tank near the station's garage, the Virginia State Department of Environmental Quality was notified at 2041 and the Surry County Local Emergency Planning Coordinator was notified at 2114. At 2334, the Virginia State Department of Environmental Quality was notified and the Surry County Local Emergency Planning Coordinator was notified at 2336, due to an estimated 200 gallon oil leak to the ground from a station switchyard transformer damaged during the tornado. </br>The NRC Resident Inspector has been notified and is on-site.</br>Notified DHS (Rickerson), FEMA (Boscoe), DOE (Turner), HHS (Hoskins), and USDA (Russell).</br>See related EN #46762</br>* * * UPDATE FROM TUCKER CARLSON TO CHARLES TEAL ON 4/19/11 AT 0756 * * *</br>The licensee exited the emergency condition at 0745 EDT on 4/19/11.
