UNIT 1 REACTOR BUILDING SECONDARY CONTAINMENT DIFFERENTIAL PRESSURE OUT OF SPECIFICATION
"On November 27, 2013 at 1001 [EST], Susquehanna Steam Electric Station operators observed secondary containment differential pressure was at 0.04 inches water gauge for Zone I (Unit 1 Reactor Building). Tech Spec Secondary Containment Operability requires a negative pressure of at least 0.25 inches water gauge. Zone II (Unit 2 Reactor Building) and III (Common Refuel Floor Area) ventilation remained in service and stable.
"Zone I differential pressure was impacted due to equipment malfunction. The inservice reactor building exhaust fan discharge damper developed an air leak at the solenoid operator. Zone 1 Building D/P was restored to within the required band at 1111 [EST] by placing the standby train exhaust fan, which was out of service for maintenance, in operation and verified to be stable. LCO 3.6.4.1 was entered for both units at 1001 [EST] and exited at 1131 [EST].
"This event is being reported under 10 CFR 50.72(b)(3)(v) and per the guidance of NUREG 1022 Rev 3 section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment System."
The NRC Resident Inspector has been informed.

NON-OCCUPATIONAL DEATH ON-SITE
"At approximately 1446 hours (CST) on November 27, 2013 a badged employee was discovered non-responsive inside a vehicle within the Owner Controlled Area. [The vehicle was located outside the protected area and in the parking lot]. On-site and off-site emergency personnel responded to the medical issue. The individual was pronounced dead at 1604 hours. No radioactive material or contamination was involved. The death was not work-related nor the result of an occupational event.
"This event is being reported under 10CFR50.72(b)(2)(xi).
"The NRC Resident lnspector has been notified."

SERVICE WATER RADIATION MONITOR REMOVED FROM SERVICE
"Planned preventative maintenance on service water piping will remove the service water radiation monitor from service. This represents a loss of emergency assessment capability under NUREG-1022, revision 3, specific to RU1.1, RU1.2, RA1.1, and RA1.2. The planned maintenance is expected to last eight hours.
"The NRC Resident Inspector was notified prior to removing the service water radiation monitor from service."
