ENS 5334819 April 2018 23:41:00Indian PointNRC Region 1Westinghouse PWR 4-LoopWhile performing a turbine startup, a turbine control anomaly caused a steam generator level transient. The rise in steam generator level above the setpoint caused the turbine to automatically trip. The high steam generator level of 73 percent caused a feedwater isolation signal at 2107 EDT, which also tripped both Main Boiler Feed Pumps. The tripping of the Main Boiler Feed Pumps auto started the motor driven Aux Boiler Feed Pumps 21 and 23. The reactor was manually tripped at 2108 EDT in accordance with AOP-FW-1 Loss of Main Feedwater. All control rods inserted. Electrical power is being provided from offsite via the Station Aux Transformer. Decay heat removal is being provided via the Atmospheric Dump Valves. An investigation into the cause of the turbine control anomaly is underway. The NRC Resident Inspector has been notified. The event did not have an affect on Unit 3 and there is no primary to secondary leakage.
ENS 5330531 March 2018 19:33:00Indian PointNRC Region 1Westinghouse PWR 4-LoopOn March 31, 2018, during the Indian Point Unit 2 refueling outage, with the reactor defueled and the head removed and located on the head stand, and all fuel from the reactor vessel removed and located in the spent fuel pool, while performing planned examinations on the 97 reactor vessel head penetrations, it was determined that one penetration could not be dispositioned as acceptable per the requirements of 10CFR50.55a for the reactor coolant system pressure boundary. The examinations are being performed to the meet the requirements of 10CFR50.55a(g)(6)(ii)(D), and ASME Code Case N-729-4, to find potential flaws/indications well before they increase to a degree that could potentially challenge the reactor vessel head pressure boundary. All other reactor vessel head penetrations have had a bare metal visual inspection completed with no other indications identified. The station is currently performing the remaining non-destructive examinations required by Code Case N-729-4. Repairs are currently being planned, and will be completed prior to entering Mode 5 from the current refueling outage. This is reportable, pursuant to 10CFR50.72(b)(3)(ii)(A) since the as found indications did not meet the applicable acceptance criteria referenced in ASME Code Case N-729-4 to remain in-service without repair. The NRC Resident Inspector has been informed. The licensee has also notified the NY Public Service Commission.

  • * * UPDATE AT 1523 EST ON 11/06/17 FROM RAMIREZ OVIDIO TO JEFF HERRERA * * *

The initial notification stated that Indian Point Unit 3 Reactor Tripped on 33 SG (Steam Generator) Low Level, this is incorrect. Indian Point Unit 3 Reactor Tripped on a Turbine Trip. The Turbine Trip was caused by a Generator Back-up Lockout Relay. The Turbine Trip was the 'first' annunciator first-out but was acknowledged instead of silenced during initial operator actions. The Turbine Trip first-out being acknowledged allowed a Low Steam Generator first-out to later annunciate. A Low Steam Generator Level is an expected condition post trip. This update does not change any actions taken by the operating team or required notifications under 10 CFR 50.72(b)(2)(iv)(B) and 10 CFR 50.72(b)(3)(iv)(A). A post trip investigation remains in progress. The licensee will notify the NRC Resident Inspector and the NY Public Commission. Notified the R1DO(Cook)

ENS 5283630 June 2017 09:04:00Indian PointNRC Region 1Westinghouse PWR 4-LoopOn June 30, 2017 at time 0130 (EDT), the Condensate Storage Tank (CST) was declared inoperable per Technical Specification 3.7.6. A pin hole sized through wall leak was discovered on the downstream side of CD-123, 32 Auxiliary Boiler Feed Pump Bearing Cooling Relief Valve, which is unisolable to the CST. No type of Non-Destructive Examination (NDE) can be used to effectively characterize the defect. Based on the inability to characterize the defect and the fact that the degradation mechanism is not readily apparent, the valve is considered inoperable because the valve has lost its ability to maintain a pressure boundary. As a result, the CST is inoperable. Currently, the CST has 580,000 gallons of water contained in the tank, which is well above the minimum required amount of 360,000 gallons. City water is the backup means to supply water to the Auxiliary Feedwater System, and this has been verified to be operable in accordance with the Actions of the Technical Specification. The CST must be restored to operable status within 7 days. The CST provides cooling water to remove decay heat and the minimum amount of water in the Condensate Storage Tank is the amount needed to maintain the plant for 24 hours at hot shutdown following a trip from full power. The CST satisfies Criteria 2 and 3 of 10 CFR 50.36. This event was determined to be reportable as a Loss of Safety Function pursuant to 10 CFR 50.72(b)(3)(v)(B). The licensee will notify the NRC Resident Inspector and the State of New York.
ENS 5282926 June 2017 18:39:00Indian PointNRC Region 1Westinghouse PWR 4-LoopOn June 26, 2017, at 1531 (EDT), Indian Point Unit 2 inserted a manual reactor trip prior to Steam Generator levels reaching the automatic reactor trip setpoint. Steam Generator water level perturbation resulted from a loss of 22 Main Boiler Feed Pump. All Control Rods verified inserted. The Auxiliary Feedwater System started as designed and supplied feedwater to the Steam Generators. Heat removal is via the Main Condenser through the High Pressure Steam Dumps. Offsite power is being supplied through the normal 138kV feeder 95332. The cause of the 22 Main Boiler Feed Pump loss is currently under investigation. Entergy is issuing a press release/news release on this issue. Unit 2 is stable and in Mode 3. There was no impact on Unit 3. The licensee notified the State of New York and the NRC Resident Inspector.
ENS 5280111 June 2017 14:35:00Indian PointNRC Region 1Westinghouse PWR 4-LoopAt Indian Point Energy Center (IPEC), Unit 3 normal letdown was isolated due to a significant body/bonnet leak on the inlet valve to Reactor Coolant Filter. Shift team took action to isolate letdown and stop the leak. The Abnormal Operating Procedure (AOP) was entered, normal letdown was isolated per procedure, and excess letdown was placed in service to balance inventory at 61 percent Pressurizer Level. This was above the Technical Specification (3.4.9) level of 54.3 percent which was exceeded at 0911 (EDT), putting the unit in a 6-hour shutdown action statement. The valve body/bonnet was torqued, successfully eliminating the leakage. Pressurizer Level was restored to the normal control band and the AOP was exited at 1136. The SM (Shift Manager) estimated the leakage at 18 gallons per minute when leak was active. No EAL (Emergency Action Level) thresholds were exceeded. This occurrence is considered a safety system functional failure per 10 CFR 50.72(b)(3)(v)(A), requiring an 8-hour NRC report. Both IPEC units are stable at full power." The licensee has notified the NRC Resident Inspector and the New York State Public Service Commission.
ENS 5275114 May 2017 15:32:00Indian PointNRC Region 1Westinghouse PWR 4-LoopOn May 14, 2017, with the Unit in Mode 4, it was identified that a single flow barrier access point (Gate C) to the 46 ft. elevation of Containment was unbolted for access to the inner crane wall to perform surveillance testing. This single flow barrier access point is required to be bolted closed to ensure the Emergency Core Cooling System (ECCS) operability basis which requires the sump barrier system to be operable in Modes 1- 4. The sump barrier system is required to prevent the transport of debris to the recirculation and containment sumps. This event is a safety system functional failure as the condition could have prevented adequate post-accident core cooling due to Design Basis Accident debris blockage of the recirculation and/or the containment sump and is reportable under 10 CFR 50.72(b)(3)(v)(D). The licensee notified the NRC Resident Inspector and the New York Public Service Commission.
ENS 5268818 April 2017 14:57:00Indian PointNRC Region 1Westinghouse PWR 4-LoopA non-licensed employee supervisor had a confirmed positive for a prohibited substance during a random fitness-for-duty test.

At 0221 (EDT) on 9/21/16, Operators at Unit 2 Secured the 21 Component Cooling Water (CCW) Pump for planned maintenance while 22 and 23 CCW pumps were in operation. When the 21 pump was secured, the discharge check valve failed to seat. This resulted in a low system pressure and reverse rotation of the 21 CCW Pump due to the discharge of the 22 and 23 CCW pumps to a common header. When system pressure dropped below 107 psig the 21 CCW pump received an auto start signal. Due to the reverse rotation, the 21 CCW pump tripped on overcurrent. Reactor Operators directed Field Operators to manually shut the 21 CCW Pump discharge valve. The 21 CCW pump Discharge Valve was closed at 0223 (EDT). This action was successful in stopping the reverse flow and restoring system parameters. During this two minute period the CCW system was declared inoperable and LCO 3.0.3 was entered. Unit 2 exited LCO 3.0.3 at 0223 (EDT) after observing system pressure and flow return to normal. The declaration of inoperability on the CCW system is considered a Loss of Safety Function for purposes of reporting under 50.72(b)(3)(v)(D). There was no reduction in power while in LCO 3.0.3 and no other issues arose. The Licensee notified the NRC Resident Inspector. The Licensee notified the Public Service Commission.

Indian Point Unit 2 is retracting the 8-hour non-emergency notification made on September 21, 2016, at 0920 EDT (EN#52254). The notification on September 21, 2016, reported a safety system functional failure (SSFF) as a result of declaring the Component Cooling Water System (CCW) inoperable due to failure of the 21 CCW pump discharge check valve (761C) to close. This condition was discovered during planned maintenance after securing the 21 CCW pump while the 22 and 23 CCW pumps were in operation. When the 21 CCW pump was secured, the discharge check valve failed to seat. This resulted in a low system pressure and reverse rotation of the 21 CCW pump due to the discharge of the 22 and 23 CCW pumps to a common header. Condition was reported as a safety system functional failure (SSFF) under 10 CFR 50.72(b)(3)(v)(D). After further investigation of the condition, a revised calculation was prepared for the CCW hydraulic model which is used to analyze CCW system performance for normal and DBA (design basis accident) modes of operation and documented in a calculation. The new calculation included the as-found condition of the 21 CCW pump discharge check valve failure to seat. Based on the results of the new calculation, the CCW system is capable of performing its design basis heat removal function during a design basis accident. Calculated flow rates with CCW aligned for Post-LOCA recirculation demonstrates that with failed open check valve 761C, the 22 CCW pump and 23 CCW pump have adequate NPSH margin, are operating below analyzed pump run out and deliver flow to the CCW system that is significantly greater than the flow required for post-LOCA recirculation. Therefore the CCW system was operable and a safety system functional failure (SSFF) did not occur as a result of failed open 21 CCW pump discharge check valve 761C. The licensee has notified the NRC Resident Inspector and will be notifying the New York Public Service Commission. Notified R1DO (Bickett).

At 1347 EDT on September 6, 2016, the non-essential service water header was declared inoperable due to what appeared to be a leak on a filet weld on a slip-on flange upstream of the 23 service water pump discharge valve SWN-2-2. (Operators) entered LCO 3.0.3 based on Engineering input with no code case to support an immediate determination of operability. The 23 service water pump was secured and the discharge valve SWN-2-2 was closed isolating the leak and restoring the non-essential SW header to operable status. With the discharge valve closed, LCO 3.0.3 was exited at 1417 EDT on September 6, 2016. The declaration of the inoperability of the non-essential service water header is considered a loss of safety function for purposes of reporting under 10 CFR 50.72(b)(3)(v). Further investigation of the leak revealed (that the leak had occurred at) a pipe flaw rather than at the weld location. An operability evaluation is ongoing. There was no reduction in power while in LCO 3.0.3 and no other issues arose. The licensee notified the NRC Resident Inspector.

Indian Point Unit 2 is retracting the 8-hour non-emergency notification made on September 7, 2016, at 1647 hours EDT (EN #52224). The notification on September 7, 2016, reported a safety system functional failure (SSFF) as a result of declaring the non-essential service water (SW) header inoperable due to discovery of a through wall leak on the discharge line from the 23 SW Pump. The leak appeared to be on the downstream fillet weld on the north side of the pipe spool piece. At the time the exact location of the leak could not be established due to the geometry of the area and its carbon fiber coating. Because there is no qualified NDE inspection technique for fillet welds and the analytical methods provided in ASME code Case N-513-3 are not applicable to fillet welds, operability of the effected section of the SW System could not be demonstrated and the SW piping was conservatively considered inoperable. Further investigation of the leak determined the leak occurred mid-pipe 1/2 inch upstream from a slip-on flange socket weld and not on the weld itself. The weld location is ASME Section XI Class 3, nuclear safety-related, Seismic Class 1. An engineering evaluation was performed of the pipe defect and concluded the identified through-wall defect on the pipe spool piece did not result in any structural, flooding, spraying condition or SW system capacity issues which would adversely impact any normal or accident design functions of the SW system or any other nuclear safety-related equipment or component to perform their design safety functions from the time of the leak occurrence to the isolation of the pipe. The structural portion of the evaluation was performed using the ASME CC N-513-3 methodology but the code case was not invoked because the flaw was isolated and a code repair was made. The 23 SW Pump discharge line spool piece is a 14 inch NPS schedule STD cement-lined carbon steel pipe having a nominal wall thickness of 0.375 inches with slip-on flanges welded on both sides with fillet welds on the exterior. The function of this spool piece is to connect the 23 Zurn Strainer outlet to the isolation valve SWN-2-2. The degradation mechanism was likely due to corrosion of the carbon steel on the underside of the cement lining due to a lining defect. The licensee will notify the NRC Resident Inspector. Notified R2DO (Krohn).

ENS 520676 July 2016 13:16:00Indian PointNRC Region 1Westinghouse PWR 4-LoopOn July 6, 2016 at 0938 EDT Indian Point Unit 2 experienced a trip from 100% steady state power during the performance of reactor protection testing. The cause of the trip is under investigation. All control rods fully inserted and all systems responded as expected. The auxiliary feedwater system actuated as expected on a low level in the steam generators which occurs as a result of a trip from full power. Auxiliary feedwater is maintaining steam generator levels and decay heat removal is via the steam generators to the main condenser. Offsite power and plant electrical line ups are normal with the exception of 13.8kV feeder 33332 which remains out of service during the replacement of breaker BT4-5. No primary or secondary code safety relief valves lifted. The reactor is in Mode 3 and stable. Indian Point Unit 3 was unaffected and remains at 100% steady state power.

ENS 5160614 December 2015 19:49:00Indian PointNRC Region 1Westinghouse PWR 4-LoopAt 1906 (EST) on 12/14/2015, Indian Point Unit 3 received a Main Generator Lockout trip signal, and the reactor automatically tripped. Site personnel reported seeing arcing on a 345kV output transmission line tower. At the time of the trip, there was moderate rain and fog in the area. The site fire brigade leader investigated the reports of arcing and found no evidence of fire; fire brigade response was not required. All automatic systems functioned as designed and all control rods inserted automatically. Auxiliary Feedwater Pumps started automatically due to expected low steam generator levels following a reactor trip from 100% power. Unit 3 is being maintained in Mode 3 with decay heat removal via steam dumps to the condenser. Offsite power remains available and in service from 138kV to the 480V safeguards buses. The cause of the Main Generator Lockout signal is being investigated. Unit 2 was not impacted and continues to operate at 100% power. The NRC Resident Inspector has been notified. After the trip, operators observed high vibrations on the 33 reactor coolant pump which eventually returned to normal range. The licensee will be notifying the New York Public Service Commission and their local Independent System Operator. A press release will be issued by the Communications Department.
ENS 515865 December 2015 18:48:00Indian PointNRC Region 1Westinghouse PWR 4-LoopAt 1731 (EST) on December 5, 2015, Indian Point Unit 2 Control Room operators initiated a Manual Reactor Trip due to indications of multiple dropped Control Rods. The initiating event was a smoldering Motor Control Center (MCC) cubicle in the Turbine Building that supplies power to the Rod Control System. The unit is stable in Mode 3 with heat sink provided by Auxiliary Feedwater and decay heat removal is via the steam dumps to the condenser. Offsite Power remains in service. The smoldering MCC cubicle had power removed from it when 24 MCC breaker tripped on overcurrent. The affected cubicle has ceased smoldering and is being monitored by on-site Fire Brigade trained personnel. The trip of 24 MCC removed power to 22 Battery Charger, 22 DC Bus remained powered from the 22 Battery without interruption, and 22 Battery Charger was subsequently repowered. The cause of the smoldering MCC is being investigated and a post reactor trip evaluation is being conducted by the licensee. There was no impact on Unit 3, which continues to operate at 100% power. The licensee has notified the NRC Resident Inspector and appropriate State and Local authorities.
ENS 5132918 August 2015 19:38:00Indian PointNRC Region 1Westinghouse PWR 4-LoopAt 1331 hours (EDT) on August 18, 2015 with the plant in mode 1, IP2 entered TS (Technical Specification) 3.0.3 upon determination by the Shift Manager that MOV-746 and 747 at the outlet of the Residual Heat Removal (RHR) Heat Exchangers may not (fully) open on an Sl (Safety Injection) signal if there was a degraded grid voltage (where the voltage at the 480V Safeguards Buses is below the minimum drop-out value of 415V and above the loss-of-voltage value of 206.6V). The MOV 746 and 747 valves are normally closed so the Sl signal with degraded voltage present could cause the fuses to fail. The time when the fuses would fail and the extent to which the MOVs open has not yet been analyzed. Immediate corrective actions was taken to replace the fuses with fuses that would not fail. The RHR trains were restored to an operable condition at 1419 and 1431 hours. This event is potentially reportable under 10 CFR 50. 72(b)(3)(ii) and 10 CFR 50.72(b)(3)(v) since the condition has not yet been fully analyzed but has been corrected. The plant remained at 100% power during the time of this event. All technical specification requirements were followed. The licensee will notify the NRC Resident Inspector and the State.

ENS 507228 January 2015 10:09:00Indian PointNRC Region 1Westinghouse PWR 4-LoopAt 0400 (EST), Indian Point Unit 3 entered LCO 3.5.4 Condition C due to both Refueling Water Storage Tank (RWST) Low Low Level Alarm channels failing. The failure was a result of freezing in the instrument lines. LCO 3.5.4 Condition C requires at least one channel of RWST Low Low Level Alarm be restored to Operable within 1 hour. At 0500, Unit 3 entered Condition D due to the required action and completion time of Condition C not being met. This requires the unit be placed in Mode 3 in 6 hours and Mode 4 in 12 hours. This failure also has resulted in a loss of safety function. Operators rely upon the RWST Low Low Level Alarms during an accident to alert them of the need to transfer injection from the RWST as a source of water to the containment sump. At 0700, Indian Point Unit 3 commenced a shutdown to be in compliance with the requirements of LCO 3.5.4 Condition D. Investigation and repair efforts were immediately put in place to correct the failure and return the function to operable. At 1000, one Channel of RWST Low Low Level Alarm was returned to operable. LCO 3.5.4 Conditions C & D were exited. The shutdown was stopped and safety function was restored. Unit 3 remains in a 7-day shutdown (LCO action statement) for one RWST Low Low Level Alarm Channel inoperable as per LCO 3.5.4 Condition B. Unit 2 is unaffected and remains at 100% power. The State of New York and the NRC Resident Inspector were notified.

ENS 5036113 August 2014 13:06:00Indian PointNRC Region 1Westinghouse PWR 4-LoopOn August 13, 2014 at 1157 EDT, the Indian Point Unit 3 Reactor Protection System automatically actuated at 100% power due to Over Temperature Delta Temperature logic. At the time of the trip, pressurizer pressure Channel 1 was in test for maintenance, though testing was suspended at this time for lunch. All control rods fully inserted on the reactor trip. All plant equipment responded normally to the unit trip. This is reportable under 10 CFR 50.72(b)(2)(iv)(B). The plant is stable in Mode 3 at this time. The Auxiliary Feedwater System actuated following the automatic trip as expected. This is reportable under 10 CFR 50.72(b)(3)(iv)(A). The Emergency Diesel Generators did not start as offsite power remained available and stable. The unit remains on offsite power and all electrical loads are stable. No primary or secondary relief valves lifted. The plant is in Hot Standby at normal operating temperature and pressure with decay heat removal using auxiliary feedwater to the steam generators, and normal heat removal through the condenser via condenser steam dumps.

ENS 502502 July 2014 14:49:00Indian PointNRC Region 1Westinghouse PWR 4-LoopOn July 1, 2014, at approximately 1500 EDT, as a result of an investigation into a report that the electronics associated with the air operated source controller of a J. L. Shepherd Model 149 Neutron Calibrator was not working properly, it was concluded that the electronics for the air operated source controller had failed. The failure would have allowed the source to be withdrawn without the electronic circuit being energized. The original source contained 8.5 Ci of Pu-Be. The calibrator is designed to expose a neutron source on a signal from a control circuit using air to withdraw the source. In this event, source withdrawal was initiated when air was aligned without the control circuit being energized; the air was immediately isolated preventing the source from being withdrawn. The calibrator has been removed from service due to the control circuit failure. The source is in the safe position, tagged and locked with the air line disabled. This failure did not result in any personnel exposure. This is reportable under 10 CFR 70.50(b)(2) since the circuit is required by design to be operable when the calibrator is used. The cause of the failure has not been determined at this time. The affected calibrator is not part of any installed plant equipment and has no impact on plant operation. The licensee has notified the NRC Resident Inspector. The licensee will notify the New York Public Service Commission.

ENS 4957322 November 2013 15:18:00Indian PointNRC Region 1Westinghouse PWR 4-LoopOn November 21, 2013 during an Access Authorization Fitness for Duty (FFD) Baseline Inspection, an NRC Inspector identified laboratory testing of a Blind FFD sample failed to provide anticipated testing results. Laboratory testing results for sample (specimen number 422136066) should have reported the sample as 'Dilute' but the laboratory report results came back as 'Negative.' In addition, the specific gravity of the sample was also outside the expected range. It should have been reported at or near 1.0015 but was reported at 1.0224 instead. The sample was submitted on March 3, 2013. The results error was not identified when the results were received which caused a violation of 10CFR26. An investigation with the laboratory has been initiated through the Medical Review Officer for IPEC (Indian Point Energy Center). Additionally an investigation with the vendor supplier of the Blind sample will be initiated. The corrective action for this event is that an extent of condition is being performed to verify that no other Blind errors exist.

The unit was manually tripped at 0741 per 2-AOP--O, Reactor Trip or Safety Injection. All control rods fully inserted. All safety systems responded as expected. The Auxiliary Feedwater (AFW) System actuated as expected. Offsite power and plant electrical lineups are normal. No primary or secondary code safety valves lifted. The 23 and 24 Main Steam Isolation Valves (MSIV) failed closed as a result of the loss of Instrument Air (IA). The 21 and 22 MSIVs remain open with the Main Condensers being used for heat sink. The reactor is in Mode 3 and stable. Unit 3 was unaffected and remains at 100% power. Preliminary investigations determined a two inch copper IA line in the switchyard which is normally buried had a failed coupling causing loss of IA to the main feedwater regulating valves. The IA line traversed an excavated area of the switchyard going to the Auxiliary Boiler Feed Pump (ABFP) Building. AFW operated using the Nitrogen backup supply to ABFP control valves until Instrument Air was restored to the ABFP building. An investigation is in progress.
