UNUSUAL EVENT DECLARED DUE TO FIRE ALARM IN CONTAINMENT NOT VERIFIED WITHIN 15 MINUTES
"Unusual Event HU2.1 declared at 1318 [CST]. A fire alarm was received in unit 2 containment at 1307 [CST]. Due to the location of the alarm, personnel were unable to verify the status within 15 minutes. At 1343 [CST], the fire alarm in containment cleared. This alarm came in shortly after a unit 2 reactor trip. The reactor trip was due to a turbine trip. Decay heat removal is via forced circulation with aux feed and steam dumps providing secondary cooling. Offsite power remains available."
The reactor trip was uncomplicated and all control rods inserted. 25B feedwater heater relief valve lifted and has reseated. No offsite assistance was requested.
The licensee has notified the NRC Resident Inspector. State and local authorities were notified.
* * * UPDATE ON 12/17/2015 AT 1734 EST FROM TOM HOLT TO DONG PARK * * *
"The licensee terminated the NOUE [Notification of Unusual Event] at 1450 CST. The basis for the termination was determination that there was no smoke or fire in the Unit 2 containment observed during containment entry.
"NRC Resident Inspectors were notified. State and local governments were notified. The health and safety of the public was not at risk."
Notified the R3DO (Valos), NRR EO (Morris), IRD (Grant), DHS SWO, FEMA Ops enter, and NICC Watch Officer. E-mailed FEMA NWC and Nuclear SSA.

AGREEMENT STATE REPORT - LEAKING RADIOGRAPHY SOURCE
The following report was received from the State of Louisiana via email:
"The RSO and crew were performing routine maintenance and leak test on industrial radiography equipment on 12/11/2015. The leak test wipes were delivered to their service company NDT Repair (LA-6631-L01) for analysis on 12/14/2015. On 12/17/2015, the RSO received a call from NDT Repair to inform him one of the leak tests came back with slightly elevated results of 0.006 microCi Ir-192. Acceptable limit is 0.005 microCi.
"The source is being transferred for disposal to SPEC [Source Production & Equipment Company], LA-2966-L01, Mfg. & Service Company in St. Rose, LA (New Orleans, LA). Also, the exposure device and associated equipment are being evaluated for breakthrough and removable contamination before re-sourcing and putting them back into service.
