AGREEMENT STATE REPORT - MOISTURE DENSITY GAUGE RUN OVER BY DUMP TRUCK
The following information was obtained from the State of Florida via facsimile:
"On Sept 28, 2013, at approximately 12:30 pm (EDT), the Florida Department of Radiation Control, received a call from the licensee, City of Palm Coast Utilities, concerning a Troxler soil moisture density gauge that had been run over by a dump truck. The licensee's RSO (Radiation Safety Officer) made the initial call from the scene where the gauge was left under truck to it keep out of the rain. However, the driver drove off and ran over the gauge. The licensee technicians had no survey meter on scene and the licensee's ARSO [Assistant Radiation Safety Officer] was on his way to assess the area with a survey meter. The Florida Department of Radiation Control verified with the licensee's RSO that the source was in the shielded condition and this was later verified by the ARSO with a survey meter. The plastic case and digital gauge face was damaged. The gauge will be retained by the licensee and later sent to Troxler for repair and leak test. Corrective action consists of training personnel and procedure changes as necessary. The Florida Department of Radiation Control has assigned the event to the Orange Park Inspection Office and Materials Office for further investigation. This office will take no further action on this incident.
"The gauge is a Troxler Model 3430 Soil Moisture Density Gauge, Serial # 20850, with Am-241 40 mCi and Cs-137 8 mCi sources."

DIGITAL RADIATION MONITOR LOW SAMPLE FLOW ALARM RECEIVED
"At 1213 EDT on September 28, 2013 Nine Mile Point Unit 2 received [Digital Radiation Monitor System] DRMS low sample flow alarm and monitor status of sample pump off for 2SWP*RE146A. The chemistry department was notified to collect and analyze grab samples per [Offsite Dose Calculation Manual] ODCM 3.3.1 as a compensatory measure with the service water radiation monitor 2SWP*CAB146A out of service. 2SWP*RE146A was restarted at 1517 EDT and declared functional.
"At 1548 EDT on September 28, 2013 Nine Mile Point Unit 2 received DRMS low sample flow alarm and monitor status of sample pump off for 2SWP*RE146B. Chemistry was again 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.
"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 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.
"The NRC Resident Inspector has been notified."
* * * UPDATE FROM CARL JONES TO CHARLES TEAL AT 0122 EDT ON 9/29/13 * * *
"The Service Water radiation monitors have been restored to service and declared functional. 2SWP*CAB146B restored after maintenance Saturday, 09/28/13 at 2243 EDT. 2SWP*CAB146A was removed from service for maintenance at 2243 EDT on 09/28/13, restored to service and declared functional Saturday, 09/28/13 at 2337 EDT."
The NRC Resident Inspector will be notified. Notified R1DO (Welling).

Update to notification:
"Received subsequent DRMS low sample flow alarm and sample pump trip at 0619 on 9/29/13 for Service Water Radiation monitor 2SWP*CAB146B. The sample pump was returned to service and subsequently tripped again. The monitor has been declared non-functional and Compensatory Actions are being taken per ODCM. Maintenance is engaged for resolution. Investigation includes potential impact from Service Water Mollusk Biocide Treatment which concluded 9/26/13."
The licensee informed the NRC Resident Inspector. Notified R1DO (Welling).
* * * UPDATE ON 10/1/13 AT 2109 EDT FROM JASON SAWYER TO HOWIE CROUCH * * *
"The Service Water Radiation monitor 2SWP*CAB146B was removed from service for inspection. The cause of the radiation monitor tripping is attributed to the scale that is forming on the flow switch sensing element. Flow switch element on 2SWP*CAB146B has been cleaned and radiation monitor has been placed back in service. The monitor was placed in service on 9/29/13 at 1200 and has been functioning properly since then. As of 2100, 2SWP*CAB146B has been declared functional and ODCM 3.3.1 actions have been exited."
The licensee will notify the NRC Resident Inspector. Notified R1DO (Joustra).
