LOSS OF EMERGENCY ASSESSMENT CAPABILITY DUE TO INOPERABLE EP SIRENS
"At 2154 hours on July 9, 2005, power was lost to the #11, Otter Creek and #12, Jacob's Creek Emergency Plan Sirens. At 2254 hours on July 9, 2005, the #11 and #12 sirens are still without power. Siren #4, WC Lake South, was previously determined to be inoperable at 1210 hours on July 6, 2005, due to being struck by lightning. With 3 of the 11 Emergency Plan sirens out of service for greater than 1 hour a major loss of emergency assessment capability exists.
"Lyon Coffey Electric is currently working to restore power to the #11 and #12 Emergency Plan sirens.
"The NRC Senior Resident Inspector has been notified.
"At 2359 hours power has been restored to the #11 and #12 sirens restoring emergency assessment capability."
The licensee contacted the dispatcher at the LLEO as an informational call.

SMALL FIRE IN WASTE (CALCINER) FURNACE
The [DELETED] calciner was loaded with low-level contaminated scrap materials. The door gasket had a small leak and the operator attempted to stop the leak. This inadvertently caused an increase in the leakage. Air contacted the hot gases leaking from the calciner and the gases were ignited. No IROFS were degraded or failed. There was a brief flame in enclosure [DELETED] from the calciner door. A prefilter in the vent duct caught fire, the HEPA filter was damaged and part of the vent duct melted. Immediately following the event, the calciner was shutdown.
There were very small potential consequences due to the fact that containment was not lost. No elevated airborne, surface contamination, or effluent radioactivity levels were detected. There were no actual health and safety consequences. The equipment is still shut down pending completion of the investigation.
The licensee notified the NRC Resident Inspector.
