HIGH PRESSURE COOLANT INJECTION SYSTEM INOPERABLE

"At 1248 EST, Unit 2 High Pressure Coolant Injection (HPCI) system was being tested for routine quarterly flow verification using surveillance test procedure SO-252-002. When HPCI turbine speed was lowered to approximately 2400 RPM, oscillations on turbine speed, flow and discharge pressure were observed. HPCI turbine speed was raised to approximately 2700 RPM and the oscillations stopped.

"Unit 2 HPCI system had been declared inoperable and LCO 3.5.1 entered at 1200 EST for the surveillance test. [This is a 14 day LCO.]

"Review by Engineering determined that cause of the oscillations warrant further evaluation and HPCI remains inoperable.

"HPCI is a single train Emergency Core Cooling Safety system. This event results in the loss of an entire safety function which requires an 8 hour ENS notification in accordance with 10CFR50.72(b)(3)(v).

"There are no other ECCS systems presently out of service."

The licensee notified the NRC Resident Inspector.

* * * RETRACTION FROM DARVIN DUTTRY TO JOHN SHOEMAKER AT 1201 EST ON 1/17/14 * * *

"NUREG-1022, Revision 3, states, 'if the retraction or cancellation of a report under this criterion is due to a revised operability determination, the retraction or cancellation should discuss the basis for why the operability determination was revised, and why it is believed that system operability was never lost (i.e., in lieu of the initial determination).'

"As indicated in the initial report, Engineering determined that the cause of the oscillations required further evaluation and HPCI remained inoperable. Additional evaluation by Engineering resulted in a conclusion that HPCI was OPERABLE with the observed oscillations at the low flow conditions. Details are as follows:

"HPCI speed/flow oscillations at low flow conditions can occur due to inherent instability at these conditions. This phenomenon is understood and documented in industry OE [Operating Experience], EPRI [Electric Power Research Institute] maintenance guidelines, and station procedures. HPCI system operation and control during the surveillance were as expected and demonstrated proper response and stable operation, with the only exception being the described oscillations at the low flow condition. This was confirmed by a review of the system response on the start-up traces. A system walkdown confirmed no abnormality with the control system equipment or governor setting. No tuning adjustments were considered to be necessary based on the low magnitude of the oscillations and their negligible impact on system operation. Unit 2 HPCI was declared OPERABLE and LCO 3.5.1 was cleared at 2308 [EST] on December 6, 2013.

"Based on the above additional information, PPL [Pennsylvania Power and Light] is retracting this report."

The licensee has notified the NRC Resident Inspector.

AGREEMENT STATE REPORT INVOLVING STUCK SHUTTER ON LEVEL GAUGE

"On January 10, 2014, the Agency received a report from the licensee's Radiation Safety Officer (RSO) stating the shutter on a Ohmart Vega model SGLG gauge containing a 500 millicurie cesium - 137 source was found stuck in the open position. Open is the normal operation position of the gauge shutter. The RSO stated a contractor was performing a calibration of a level detector on January 9, 2014, when they could not get the gauge shutter to close. The contractor sprayed the shutter with a light oil and attempted to rotate the handle and operating arm. While trying to free the shutter, the operating arm separated from the gauge. The contractor was able to insert the operating rod into the gauge, but the shutter would not move. The manufacturer has been contacted to assist in the repair or replacement of the gauge. No exposure resulted from this event and the current position of the gauge shutter does not create any additional exposure risk to any personnel. A contact dose rate survey of the gauge was conducted and the highest reading observed was 1.2 millirem per hour. Additional information will be provided as it is received in accordance with SA-300."

EMERGENCY RESPONSE FACILITIES OUT OF SERVICE DUE TO PLANNED MAINTENANCE

"This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because work activities affect the functionality of emergency response facilities. This condition does not affect the health and safety of the public or station employees.

"At approximately 1022 [EST] on January 13, 2014, planned maintenance activities began on the Emergency Operations Facility (EOF) heating ventilation and air conditioning (HVAC) system. The scope of the maintenance is to obtain samples of the charcoal filter. The planned work activity duration is expected to be approximately 20 hours ending on January 14, 2014. In addition, a multi-day (5 days) maintenance activity will begin on January 13, 2014 on the Technical Support Center (TSC) HVAC system, involving flow-balancing the system, which may involve intrusive maintenance during certain intervals. This intrusive maintenance will render the TSC HVAC system non-functional. This planned work activity is expected to be completed on January 17, 2014. The EOF and TSC HVAC systems will be restored periodically throughout this maintenance period.

"If an emergency is declared requiring emergency facility activation during this period, the emergency facilities will be staffed and activated using existing emergency planning procedures. If relocation of the emergency facilities becomes necessary, the Emergency Director will relocate the emergency response organization to an alternate location in accordance with applicable site procedures. The Emergency Response Organization team has been notified of the maintenance and the possible need to relocate during an emergency.

"An update will be provided once the EOF and TSC ventilation systems have been restored to normal operation and all planned maintenance is complete. The NRC Resident Inspector has been notified."

* * *UPDATE PROVIDED BY KEVIN ABELL TO JEFF ROTTON AT 1043 EST ON JANUARY 17, 2014 * * *

The planned maintenance is complete and the EOF and TSC have been restored to normal operation.

PYRO PANEL TAKEN OUT OF SERVICE FOR PLANNED MAINTENANCE

"At 0925 [CST] on January 17, 2014, the Unit 1 pyro panel (smoke detection panel) was removed from service for required maintenance. The pyro panel was declared non-functional when it was removed from service. Compensatory measures have been established for all affected areas except the Unit 1 Containment Building. Since a fire in Containment is an entry condition for the site's Emergency Plan, this is considered a loss of emergency assessment capability and is being reported per 10CFR50.72(b)(3)(xiii). Containment temperatures are being monitored while the pyro panel is out of service, however, this is not considered a satisfactory compensatory measure for maintaining effective assessment capability.

"The site NRC Resident Inspector has been notified."

* * * UPDATE FROM DARRIN GARD TO CHARLES TEAL AT 2202 EST ON 1/17/14 * * *

The pyro panel was restored to service as of 1650 CST. The licensee has notified the NRC Resident Inspector.

FUEL OIL FOUND DURING CORE DRILLING

"On January 17, 2014, at 1400 EST Sequoyah (SQN) notified the Tennessee Department of Environment and Conservation (TDEC) of a condition that was identified on December 4, 2013, while conducting core samples. The core drilling contractor detected a petroleum odor, notified the SQN Environmental Group who observed the core drilling and confirmed a slight petroleum odor from a core boring in which water was detected at approximately 41 feet below the ground surface. At that time, as a result of the type of core drilling that was conducted, TVA could not verify if there were petroleum products in the groundwater.

"SQN obtained geoprobe boring samples to determine the extent and the depth of the petroleum. Petroleum product was detected in the soil between 30 and 35 feet in depth. This condition has been determined to be associated with a legacy diesel fuel oil leak at SQN in the 1990's and was previously reported. SQN previously completed a remediation project from 1992 - 2010, with oversight from TDEC. The petroleum product appears to be isolated at approximately 30 to 35 feet in depth, is in a perched water table not utilized for drinking water, and appears to be isolated to the diesel building area. To verify the petroleum product is isolated; TVA is conducting additional geoprobe boring to help define the limited area impacted by the legacy diesel fuel oil leak.

"The Sequoyah NRC Resident Inspectors have been notified."

UNIT 2 PYRO PANEL NON-FUNCTIONAL DUE TO UNKNOWN EQUIPMENT PROBLEMS

"At 10:20 [CST] on January 18, 2014, the Unit 2 Pyro Panel (fire/smoke detection panel) was declared non-functional due to an unknown equipment problem. Compensatory measures (e.g. continuous roving fire watches) have been established for all affected areas with the exception of the Unit 2 Containment Building. Containment fire watches have been established per the FSAR, which includes monitoring various temperatures, pressures, and other parameters for Containment, and systems associated with containment. However, this is not considered a satisfactory compensatory measure for maintaining effective assessment capability. Since a fire in Containment is an entry condition for the site's Emergency Plan, this is considered a loss of emergency assessment capability, and is being reported per 10CFR50.72(b)(3)(xiii).

LOSS OF SHIELD BUILDING GASEOUS RADIATION MONITOR

"2R-22, Unit 2 Shield Building Ventilation Gaseous Radiation Monitor was removed from service at 0216 CST on 01/20/2014 due to a broken belt. 2R-22 is important to the site's emergency plan for Notification of Unusual Event and Alert classifications in the event of an unplanned gaseous release from the Unit 2 Shield Building stack. It is also used for offsite dose projection calculations. There is no backup instrumentation or compensatory measure to perform these functions while 2R-22 is out of service. This results in a loss of emergency assessment capability, thus is reportable per 10CFR 50.72(b)(3)(xiii).
