SERVICE WATER RADIATION MONITOR OUT OF SERVICE
"At 2204 EDT on October 7, 2013, Nine Mile Point Unit 2 received DRMS [Digital Radiation Monitor System] low sample flow alarm and sample pump trip for 2SWP*CAB146B. The chemistry department was notified to collect and analyze grab samples per ODCM 3.3.1 as a compensatory measure with the Service Water Radiation Monitor 2SWP*CAB146B out of service.
"Attempts to restart 2SWP*CAB146B within 1 hour were unsuccessful. 2SWP*CAB146B remains Non-Functional. Technicians are being called in to restore the monitor to Functional status.
"The Service Water Radiation Monitors are necessary for accident assessment and are credited for Emergency Action Level (EAL) classification. The inability to classify an EAL due to an out of service monitor is considered a loss of assessment capability per 10 CFR 50.72(b)(3)(xiii). This condition does not affect the health or safety of the public or the operation of the facility. Compensatory actions remain in place to sample per the requirements of the ODCM 3.3.1.
"The NRC Resident Inspector has been notified."

"At 1027 EDT on October 8th, 2013 Nine Mile Point Unit 2 received a DRMS low sample flow alarm and sample pump trip for 2SWP*CAB146A. Service Water Radiation Effluent Monitor SWP*CAB146B remains NONFUNCTIONAL, but in service from the previous shift with required compensatory measures per ODCM 3.3.1 already in place (12 hour grab samples/30 day restoration).
"Attempts to restore 2SWP*CAB146A within 1 hour were unsuccessful. As of 1220 EDT on October 8th, 2SWP*CAB146A monitor has been restored to service and is now capable of providing information for emergency assessments, the monitor is in confidence run for restoration to FUNCTIONAL status.
"The Service Water Radiation Monitors are necessary for accident assessment and are credited for Emergency Action Level (EAL) classifications. The inability to classify an EAL due to an out of service monitor is considered a loss of assessment capability per 10 CFR 50.72 (b)(3)(xiii). This condition does not affect the health or safety of the public or the operation of the facility because the monitor is currently back in service.

PLANNED MAINTENANCE CAUSING LOSS OF METEOROLOGICAL TOWER DATA
"A planned maintenance evolution at the Duane Arnold Energy Center (DAEC) will de-energize the Meteorological Data Tower. No other indications or annunciators will be unavailable during this maintenance to affect the plant's ability to assess or monitor an accident or transient in progress. National Weather Service data is expected to be available throughout the duration of the planned maintenance. A follow up notification will be provided when power to the Meteorological Data Tower has been restored."
The NRC Resident Inspector has been notified.
* * * UPDATE AT 1718 EDT ON 10/07/13 FROM TERRY BRANDT TO HUFFMAN * * *
Maintenance activities on the Meteorological Data Tower is complete and the tower has been returned to service.
The licensee has notified the NRC Resident Inspector. R3DO (Skokowski) notified.

POTENTIAL REACTOR COOLANT SYSTEM PRESSURE BOUNDARY LEAKAGE IDENTIFIED
"The following event description is based on information currently available. If through subsequent reviews of this event additional information is identified that is pertinent to this event or alters the information being provided at this time a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.
"At approximately 2100 MST on 10/06/13, while performing planned routine visual examinations of the Unit 3 reactor vessel bottom mounted instrumentation (BMI) nozzles, a white residue was identified around the annulus region of BMI penetration number 3. The BMI visual examinations are performed using remote video and photographic equipment to meet the in-service inspection requirements of 10 CFR 50.55a(g)(6)(ii)(E) and ASME Code Case N-722-1. At this time, no other indications of leakage have been identified and inspections of the remaining BMI penetrations are ongoing.
"Following review of the photographic images by qualified engineering personnel, at 0219 [MST] on 10/07/13, it was determined, based on past and present photographic evidence, the white residue is most likely dry boric acid resulting from reactor coolant system pressure boundary leakage. An activity to sample and analyze the white residue is being planned and will be performed as soon as possible. This notification is being made for a degraded condition pursuant to the requirements of 10 CFR 50.72(b)(3)(ii)(A).
"The NRC Resident Inspectors have been informed of this condition."

VENT STACK AND AREA RADIATION MONITORS TAKEN OUT OF SERVICE FOR MAINTENANCE
"This is a report of a loss of emergency assessment capability as required by 10CFR50.72(b)(3)(xiii).
"On October 7, 2013 at 1804 CDT, with Unit 1 in Mode 6 during a refueling outage, power was interrupted to all Unit 1 vent stack radiation monitors and area radiation monitors as part of a pre-planned activity to connect the radiation monitors to an alternate temporary power supply to support deenergizing the normal power source for preventative maintenance. The connection to the alternate supply was completed and power was restored to the vent stack radiation monitors and area radiation monitors at 1833 CDT. While the radiation monitors were without power, pre-planned compensatory measures were implemented where possible to monitor vent stack discharge and to minimize activities that posed a potential for release.
"At the completion of the preventive maintenance on the normal power supply, power to the vent stack radiation monitors and area radiation monitor will again be briefly interrupted to reconnect the normal power source to the monitors. The pre-planned compensatory measures will again be utilized during this power interruption. An update to this report will be provided following the restoration of normal power to the radiation monitors.
"The NRC Resident Inspector has been informed."

"On October 13, 2013 at 0217 CDT, with Unit 1 in defueled mode during a refueling outage, power was interrupted to all Unit 1 vent stack radiation monitors and area radiation monitors as part of a pre-planned activity to transfer the radiation monitors back to their normal power supply. The connection to the normal supply was completed and power was restored to the vent stack radiation monitors and area radiation monitors at 0245 CDT. Pre-planned compensatory measures were implemented where possible to monitor vent stack discharge and to minimize activities that posed a potential for release."
Notified R2DO (Widmann) and the licensee will notify the NRC Resident Inspector.
