| ENS 52795 | 8 June 2017 19:27:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release 10 CFR 50.72(b)(2)(iv)(B), RPS System Actuation 10 CFR 50.72(b)(3)(iv)(A), System Actuation 10 CFR 50.72(b)(2)(iv)(A), System Actuation - ECCS Discharge | Automatic Reactor Scram After Main Turbine Control Logic Loss of Power | At 1527 hrs (EDT) on June 8, 2017, Susquehanna Steam Electric Station Unit 1 reactor automatically scrammed due to a loss of Main Turbine Electro-Hydraulic Control (EHC) logic power causing a High Flux Reactor Power RPS (Reactor Protection System) trip. All control rods (fully) inserted and both reactor recirculation pumps tripped due to reaching reactor water level 2. Reactor water level lowered to -49 inches causing Level 3 (+13 inches) and Level 2 (-38 inches) isolations. HPCI (High Pressure Coolant Injection) and RCIC (Reactor Core Isolation Cooling) automatically initiated and were overridden by control room operators after RPV (Reactor Pressure Vessel) water level was restored to the normal band with feedwater. HPCI and RCIC injected to the Reactor Coolant System during reactor level stabilization. All isolations and initiations occurred as expected. No main steam relief valves opened. Pressure was controlled via main turbine bypass valve operation. All safety systems operated as expected. Secondary Containment Zone 1, 2, and 3 differential pressure lowered to 0 inch WG (Water Gauge) due to a trip of the Reactor Building Ventilation system that resulted from Unit 1 Level 2 isolation. Differential pressure was restored to Zones 1, 2, and 3 by the initiation of Standby Gas Treatment System on the Unit 1 Level 2 initiation. Unit 1 reactor is currently stable in Mode 3. Investigation into the loss of Main Turbine EHC logic power is underway. The NRC Resident Inspector has been notified. A voluntary notification to PEMA and press release will occur. The suspected cause of the loss of power to the EHC logic circuit is ongoing maintenance on the system. | Reactor Coolant System Feedwater Secondary containment Main Turbine Reactor Recirculation Pump Reactor Building Ventilation Standby Gas Treatment System Control Rod Main Steam | 05000387/LER-2017-005 |

| ENS 45534 | 1 December 2009 23:00:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Onsite Flooding Caused by Make-Up Supply Line Failure | The following transmission was made as a voluntary notification at 1800 EST: On 12/01/09 at 1410 (EST), due to a Unit 2 cooling tower make-up supply line failure, a valve vault was flooded and overflowed at several thousands of gallons per minute flow. The local fire company was contacted to provide equipment assistance in pumping out the vault. The river water overflowing the vault entered nearby storm drains and a nearby building housing non-safety related equipment. There are no injuries or an emergency of any kind. The water entering the storm sewer does not constitute a reportable spill. Unit 2 reactor power was reduced to 80% to minimize cooling tower impact. The Pennsylvania Emergency Management Agency was notified at 1800 EST. Various other local and state agencies have been advised of the event. Subsequently, notifications were made to the following agencies: Salem Township Supervisor Chairman State Senator Baker State Rep. Boback Columbia County Commissioner Soberick Federal Affairs to notify US Rep. Kanjorski's staff. Although the impact of this make-up supply line failure to the environment is insignificant (Radiological levels are less than lower limit of detection), its occurrence coupled with subsequent notifications to aforementioned agencies is likely to cause heightened public or government concern. Thus, Susquehanna Steam Electric Station is making a four hour ENS notification pursuant to 10CFR50.72(b)(2)(xi). A press release is not planned at this time. The licensee has notified the NRC Resident Inspector. | ||
