AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS
The following summary was received from the state of Colorado via email:
Four tritium exit signs, containing 7.5 Ci each, were determined lost, disposed of before the current manager took the management position.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

AGREEMENT STATE REPORT - VEHICLE ACCIDENT INVOLVING A TROXLER GAUGE
The following was received via email from the State of Florida:
"Vehicle accident involving a transported Troxler gauge. Driver rear ended the vehicle in front and was transported to hospital. Troxler case was in back of pick up truck and apparently suffered a broken clasp but gauge still intact. [Florida State Inspector] is responding to investigate and take possession of the gauge until the RSO arrives on scene."
Incident Number: FL17-300

SYSTEM ACTUATIONS DUE TO OPENING OF FEEDER BREAKER TO SHUTDOWN BOARD
"On December 20, 2017, at 1040 Eastern Standard Time (EST), the Watts Bar Nuclear Plant (WBN) 1B-B 6.9kV Shutdown Board (SDBD) normal feeder breaker opened. The loss of voltage to the 1B-B SDBD resulted in the start of the 1B-B Motor Driven Auxiliary Feedwater (MDAFW) pump, the Unit 1 Turbine Driven Auxiliary Feedwater (TDAFW) pump, and the start of all four Emergency Diesel Generators (EDGs). Power was restored to the 1B-B 6.9 kV SDBD when it loaded on to its associated EDG.
"Following initial investigation, the 1B-B 6.9 kV SDBD was transferred to its alternate offsite power source, Common Station Service Transformer (CSST) C at 1217 EST. At 1230 EST, the 1B-B 6.9 kV SDBD alternate feeder breaker opened. The loss of voltage to the 1B-B SDBD did not result in the restart of the 1B MDAFW pump, the Unit 1 TDAFW pump, or EDGs; this equipment remained running from the earlier event. Power was restored to the 1B-B 6.9 kV SDBD when it loaded on to its associated EDG.
"Restoration of normal offsite power to the 1B-B SDBD was completed at 1654.
"Other than several common Unit Technical Specifications having not been met, Unit 2 was not operationally impacted by the transfer of the 1B-B Shutdown Board to onsite power and remains in Mode 1 at 100% power.
"This report is made per 10 CFR 50.72(b)(3)(iv)(A).
"NRC Resident Inspector has been notified."
The licensee investigation continues for the cause of the event.

EMERGENCY ALERT SYSTEM OUT OF SERVICE
"During review of the documentation for the 11/16/17 outage of the NOAA/NWS [National Oceanographic and Atmospheric Administration/National Weather Service] tower, it was identified that there was also record of a trouble ticket being issued on 11/19/17 for the NOAA/NWS tower. Further discussions with the National Weather Service determined that the tower did experience an outage on 11/19/17 which affected the ability to activate EAS [Emergency Alert System]/Tone Alert Radios. Final determination that the EAS/Tone Alert Radios were affected during this outage was made at 1559 [CST], which was the time that the National Weather Service sent the e-mail to the EP [Emergency Planning] Manager and EP Offsite Coordinator with notification that activation of the EAS/Tone Alert Radios was affected during the outage. This is considered to be a major loss of the Public Prompt Notification System capability, and is reportable under 10CFR 50.72(b)(3)(xiii).
"The transmission outage was on 11/19/2017 0853 until 1100 but CNS [Cooper Nuclear Station] was not notified until 1559 on 12/20/2017.
"The NRC Senior Resident has been informed"
