"On August 14, 2015, the Grand Gulf Nuclear Station (GGNS) determined that less than 75% of the population in the ten mile EPZ could have been notified using the alert notification system (sirens). This condition existed between the time period starting sometime after 1800 [CDT] on Friday, July 31, 2015 until 1630 [CDT] on Monday August 3, 2015.
"The completion of this notification was delayed because at the time of discovery the available information and built in system redundancy supported a conclusion that greater than 75% of the population could have been notified using the siren system. The diversity of the systems required repairs and testing to be coordinated with local officials in both Mississippi and Louisiana.
"At 1000 CDT hours on August 3, 2015, GGNS was informed that the Claiborne County Emergency Operations Center (EOC) siren activation equipment had lost power over the weekend. Investigations and repairs were initiated by Claiborne County Emergency management upon discovery. The system was repaired and functional at 1630 hours on August 3, 2015."
The licensee reported that 30 of 42 sirens lost power.
The NRC Resident Inspector has been notified.
* * * UPDATE FROM DAVID BURRUS TO JOHN SHOEMAKER AT 1243 EDT ON 9/23/15 * * *
"Based on a detailed investigation (an apparent cause evaluation performed by the Grand Gulf Nuclear Station) into the events surrounding the power interruption at the Claiborne County EOC, Entergy has determined that the emergency power source for the Claiborne County EOC was available and would have been manually established by the Claiborne County EOC Emergency Director if the facility was activated.
"Upon discovery of the problem, maintenance was immediately performed on the system to reestablish the normal source of power to the Claiborne County EOC. This maintenance required approximately 8 hours to complete. This maintenance activity required the lock-out tag-out of all power (normal and back-up) to the facility.
"During the time period that all power was removed from the facility, the pre-established and pre-approved back-up notification system was available and would have been utilized to complete the required public notifications.
"Supplement 1 to Revision 3 of NUREG-1022, Event Reporting Guidelines, 10CFR50.72(b)(3)(xiii), states in part the following: NEI 13-01 proposes that for extended unplanned losses of the primary public alerting system, a report would not be required if the FEMA approved backup alerting method was available and the primary public alerting system was returned to service within 24 hours This 24-hour cap is put into place to limit reliance on a less capable backup alerting method. However, because some backup capability exists, NRC action or awareness is not likely warranted in such scenarios for which the loss of the primary capability is limited in duration. As a result, a report would not be required
"Therefore, Entergy is updating the above notification based on the developed information that the Claiborne County EOC Emergency Director understood how and would have manually established electrical power to the alert notification system if required and because the maintenance period was less than the 24 hour allowable period established in Supplement 1 to Revision 3 of NUREG-1022."
The licensee has notified the NRC Resident Inspector.

The following information was provided by the State of South Carolina via email:
"The licensee provided notification of a stuck shutter, on a Berthold Model LB7440D fixed gauging device, discovered while performing a semi-annual shutter check. The gauging device contains 30 mCi of Cs-137. The device remains mounted to the process piping with no gap available to permit personnel exposure to the radiation beam. A licensed contractor has been contacted and will proceed with corrective maintenance on the shutter mechanism within the next 30 days."

The following information was obtained from the Commonwealth of Kentucky via facsimile:
"[This failure was] not previously reported by licensee to RHB [KY Radiation Health Branch], but recent inspection of facility [performed on 8/4/2015] showed that the defect was noted on 3/10/15 during the routine 6 month inventory and shutter check updates.
"Equipment failure: On-Off shutter mechanism on KAYRAY/Sensall 7062BP (Cs-137, 100 mCi; Serial No. 2975) fixed gamma gauge has broken spring. Shutter is kept in open position by makeshift wire fastener. No release of radioactivity. (Sealed Source capsule model 7700Y). Last leak test on 3/19/15 showed MDA (<5 nCi)."

The following information was received from the State of Florida via email:
"The RSO [Radiation Safety Officer] at Georgia Pacific Corporation in Palatka, Florida called to report [to the State of Florida that] a fixed Cesium-137 source installed on the top half of a tank has the shutter stuck open. Device originally had 2,000 mCi, but now is estimated to have 892 mCi of Cs-137. This same equipment was reported with the same defect on April 9, 2015 (FL15-025). There is no report of any over exposure of personnel and no leaks (confirmed by leak test). The location of the device prohibits the access of personnel and the shutter is only closed when maintenance or repair is performed. The RSO has put in a work order for repair and will provide a copy of a report confirming the equipment was serviced/repaired back in April. Initial NRC Event Notification #50971."
The fixed gauge manufacturer is Kay-Ray, Model number - 7063P, serial number 10682F.

| Event Text ALERT DECLARED DUE A FIRE GREATER THAN 15 MINUTES OUTSIDE OF THE FACILITY
At 2019 CDT, the licensee declared an Alert due to a truck fire, outside of the protected area, that lasted greater than 15 minutes. The truck was awaiting entry to the plant to deliver materials when the truck driver noticed smoke emanating from the dash. He attempted to put out the fire using a handheld extinguisher but was unsuccessful so he left the vehicle and notified licensee employees.
The licensee contacted the Massac County and Metropolis Fire Departments who responded to the site and put out the fire. The cab of the truck is considered a total loss but the trailer was not affected by the fire and remains intact. The licensee is awaiting clearance from the fire department to enable them to take swipes of the trailer to verify no contamination exists.
At 2055 CDT, once they determined the fire was out, the licensee downgraded the Alert to a plant emergency.
The licensee notified local authorities and the Illinois Emergency Management Agency of the event.
Notified DHS SWO, FEMA Ops Center, USDA Ops Center, HHS Ops Center, DOE Ops Center, DHS NICC Watch Officer and the EPA EOC.
* * * UPDATE FROM SEAN PATTERSON TO HOWIE CROUCH AT 2329 EDT ON 09/20/15 * * *
At 2216 CDT, the licensee declared all clear for the event when the swipes taken on the trailer did not indicate a spread of contamination.
