SALT SERVICE WATER PUMP INOPERABILITY DURING POSTULATED DEGRADED VOLTAGE CONDITIONS
"On Thursday, September 22, 2011 at 1452 [EDT], with the reactor at 100% core thermal power and steady state conditions, Pilgrim Nuclear Power Station (PNPS) conservatively declared both Salt Service Water (SSW) subsystems inoperable when engineering analysis determined that inrush current on pump restart may exceed the thermal overload trip relay settings during certain degraded voltage conditions. A 24-hour Limiting Condition for Operation action statement was entered.
"Entergy/Pilgrim is in the process of implementing temporary modifications to correct this issue. This potential concern has no impact on public health and safety. This 8-hour notification is being conservatively reported in accordance with 10 CFR50.72(b)(3)(ii)(B).
"The NRC Resident Inspector has been notified."
The licensee will notify the Massachusetts Emergency Management Center.
* * * RETRACTION FROM DAVID NOYES TO VINCE KLCO ON 11/20/2011 AT 0733 EST* * *
"Event Notification 47288 was conservatively made to ensure that the Eight-Hour Non-Emergency reporting requirements of 10 CFR 50.72 were satisfied pending further evaluation of Salt Service Water (SSW) subsystem operability during certain degraded voltage conditions.
"Pilgrim Station has subsequently evaluated the impact of the Salt Service Water (SSW) pump motor operating load; potential degraded voltage conditions on thermal overload settings; and pump motor restart requirements; and determined that reasonable assurance of SSW subsystem operability existed. Both SSW subsystems were evaluated to be capable of satisfying the system safety function of providing cooling water to the Reactor Building Closed Cooling Water System heat exchangers during accident and transient conditions. Pilgrim 's evaluation considered manufacturer's data for the thermal overload relays, site specific shop testing, and reliable grid conditions which minimize the potential for extended operation with 4 kV buses operating at just above degraded voltage relay trip settings. This past operability evaluation concluded that the SSW pumps would support continuous operation of the SSW subsystems.
"Therefore, the initial 50.72 report is being retracted."
The licensee will notify the NRC Resident Inspector.

AGREEMENT STATE REPORT - LOSS OF A TRITIUM SIGN
The following report was received from the state via e-mail:
"Safety Light Model 2040-50-20, Serial Number A10 1821 with 12 Ci of H-3 was shipped in July of 1991 to the facility. In 2002-2003, the facility was remodeled. The facility was sold in 2004. The new owner assumed that they still had the sign and continued to pay the annual fee. This year, one of the owners sold his portion of the business and new staff questioned where the sign was when they received the annual fee notice. The staff believes that the sign was removed at the time of remodeling in 2002-2003."
Nebraska Item Number: NE110009
The licensee determined the sign was lost on 11/4/2011 and reported it to the state on 11/14/2011.

LOCAL POWER RANGE MONITOR (LPRM) STORED IN SPENT FUEL POOL CANNOT BE LOCATED
"At 1330 [CST] on 11/18/11, Nuclear Engineering reported to Operations that during a Special Nuclear Material (SNM) Physical Inventory they were unable to locate an individual LPRM [Local Power Range Monitor] detector that was believed to be loose in the bottom of the Spent Fuel Pool. Efforts remain in progress to locate the material in the pool."
The licensee stated that during a previous refueling, a 4-detector LPRM string had been removed from the core and placed in the spent fuel pool. At the time, the string had been cut and a single detector at the bottom of the string had fallen to the bottom of the spent fuel pool under the fuel racks. Today, the licensee attempted to retrieve the LPRM detector for placement in a special storage canister in a controlled location that could be easily inventoried. During the retrieval attempt, the licensee could not locate the LPRM detector. There is no indication at this time that the detector has been inadvertently removed from the spent fuel pool and disposed of. The licensee believes that the detector is still in the pool and just needs to be located. The specific information on the detector was not available at the time of this report but the licensee is conservatively assuming the it contained greater than 1 gram of Uranium-233 and is therefore reportable under 10 CFR 74.11.
The licensee has notified the NRC Resident Inspector. |

THE LOW PRESSURE SAFETY INJECTION SYSTEM WAS SUBJECTED TO HIGH PRESSURE RESULTING IN BOTH TRAINS BEING DECLARED INOPERABLE
"On November 19, 2011, Unit 1 was in Mode 3. Boration of the four reactor coolant system (RCS) cold leg injection lines was in progress using High Pressure Safety Injection pump 'A'.
"During this activity, 'SI CHK VLV Leak Pressure Hi' alarms were received at 0828 [MST]. The 'A' and 'B' Low Pressure Safety Injection (LPSI) subsystems were declared inoperable because the pressure downstream of the motor operated LPSI injection valves was above 1525 psia. This elevated pressure potentially impacts the ability of the LPSI RCS loop injection valves to open. The high differential pressure may exceed the capability of the motor operator. All four injection line pressures were found above 1525 psia and LCO 3.0.3 was entered due to both trains of LPSI being inoperable. At 0839 [MST], pressure in the 'A' train injection lines was lowered below 1525 psia and 'A' LPSI subsystem was declared operable and LCO 3.0.3 was exited. At 0842 [MST], pressure was reduced below 1525 psia on the 'B' train injection lines and the 'B' LPSI subsystem was declared operable and LCO 3.5.3 condition A was exited.
"This call is being made to report a condition that could have prevented the fulfillment of a safety function required to mitigate the consequences of an accident and unanalyzed condition that existed for 11 minutes while both LPSI subsystems were inoperable.
"The NRC Resident Inspector has been notified." |

AUTOMATIC REACTOR SCRAM WHILE PERFORMING TURBINE BYPASS VALVE TESTING
"While performing a regularly scheduled Turbine Bypass Valve surveillance, prior to Turbine Bypass Valve movement, a 'B' half scram [signal] was received. Operators immediately suspended testing. Approximately 10 seconds later, a full Reactor Protection System actuation occurred. Following the reactor scram, reactor water level lowered below the Group II isolation initiation setpoint of +9 inches, [resulting in containment valve isolations]. There were no radioactive releases associated with this event.
"No other alarms were received prior to the RPS actuation. The cause of the reactor scram is under investigation at this time.
"Also, due to the reactor scram, discharge canal temperature rate of change exceeded plant requirements. As a result, the State of Minnesota, and appropriate local agencies will be notified."
All control rods inserted and the scram is considered uncomplicated. The plant is in a normal shutdown electrical configuration.

MANUAL REACTOR TRIP DUE TO LOSS OF CONDENSER VACUUM DURING STARTUP
Millstone Unit 3 was manually tripped at low power during startup following the loss of condenser vacuum. The loss of vacuum was caused by the loss of the auxiliary steam boiler. The auxiliary steam boiler supplies gland seal steam to the turbine at low power and without the gland seal steam, the licensee could not maintain a condenser vacuum.
All rods fully inserted and there were no complications during the trip. All systems functioned as required and the unit is stable in Mode 3. There was no impact on Unit 2.
The licensee has notified state and local authorities and the NRC Resident Inspector. |
