60-DAY OPTIONAL TELEPHONIC NOTIFICATION OF INVALID SYSTEM ACTUATION
"In accordance with 10CFR50.73(a)(2(iv)(A), this telephone notification reports an invalid actuation of the Unit 1 train A (1A) Emergency Diesel Generator (DG) on October 1, 2012, at 1403 hours. At the time of the event Unit 1 was in Mode 5, Cold Shutdown. The 1A DG was undergoing a surveillance procedure that verifies a safety injection override signal when a technician actuated the incorrect under voltage relay which resulted in the inadvertent start of the 1A DG. The engine functioned successfully and ran unloaded, as expected. The cause is attributed to the technicians failing to verify they were actuating the correct relay. This condition was entered into the corrective action program."
The licensee notified the NRC Resident Inspector and the Illinois Department of Nuclear Safety.

TECHNICAL SUPPORT CENTER (TSC) / EMERGENCY OPERATIONS FACILITY (EOF) OUT-OF-SERVICE FOR PLANNED MAINTENANCE
"On October 01, 2012, at approximately 09:00 hours Eastern Daylight Time (EDT), the Brunswick TSC/EOF Emergency Ventilation System is scheduled to be removed from service to perform planned maintenance consisting of emergency filtration unit charcoal testing and replacement. The removal of the ventilation system can potentially affect the TSC and EOF habitability during a declared emergency requiring activation. If an emergency is declared requiring TSC/EOF activation during this period, the facilities will be staffed and activated using existing emergency planning procedures unless uninhabitable due to ambient temperature, radiological, or other conditions. The Emergency Response Organization duty team has been notified of the maintenance and the possible need to activate the TSC and EOF at their alternate locations. This condition has no adverse impact to the health and safety of the public.
"The ventilation system is scheduled to be out of service for approximately 2 days."
The licensee informed the NRC Resident Inspector.

EMERGENCY RESPONSE DATA SYSTEM IS UNAVAILABLE FOR SERVICE
"Seabrook personnel determined that the Emergency Response Data System (ERDS) is unavailable due to a malfunction of its process computer. The condition occurred around 0430 EDT today after a plant electrical bus was de-energized and subsequently reenergized during a maintenance activity. The plant is presently in a refueling outage with the reactor vessel defueled. Following repair of the process computer, Seabrook expects to return ERDS to service later today.
"This event is being reported in accordance with 10 CFR50.72(b)(3)(xiii), loss of emergency preparedness capabilities, for loss of the ERDS function.
"The NRC Resident Inspector has been notified of this event."
* * * UPDATE FROM MIKE TAYLOR TO HOWIE CROUCH AT 1333 EDT ON 10/1/12 * * *
The ERDS system has been returned to service. The licensee will be notifying the NRC Resident Inspector.

TECHNICAL SUPPORT CENTER OUT-OF-SERVICE FOR PLANNED MAINTENANCE
"On October 1, 2012, at approximately 0740 hours [CDT], the Kewaunee Power Station Technical Support Center (TSC) ventilation system was removed from service for planned TSC ventilation system maintenance. The removal of the ventilation system potentially affects the TSC habitability during a declared emergency requiring activation. The Emergency Response Organization (ERO) team has been notified of the maintenance and the possible need to relocate during an emergency. If an emergency is declared and TSC ERO activation is required, the TSC will be staffed and activated unless the TSC becomes uninhabitable due to ambient temperatures, radiological, or other conditions. If relocation of the TSC staff becomes necessary, the Station Emergency Director will relocate the staff to an alternate TSC location.
"The ventilation system is expected to be out of service for approximately 7 hours.
"This condition is being reported in accordance with 10CFR50.72(b)(3)(xiii) as an event that results in a major loss of emergency assessment capability.
"The NRC Resident Inspector has been notified."
