Event Text

PLANNED MAINTENANCE ON RADIOLOGICAL MONITOR

"At 0500 [CST] today (January 12, 2015), planned maintenance activities commenced on the Reactor Building Separate Particulate Iodine and Noble Gas (SPING) monitor. Work on the SPING affects classification and assessment of the Emergency Plan for a radiological release through the Reactor Building Vents. In the case of a radiological event, the Reactor Building Ventilation will be isolated via Area Radiation Monitors (ARM) in the ducting and the Main Chimney SPING will be used for classification and assessment. This would be the normal response for a radiological event.

"This maintenance activity is expected to be longer than 72 hours. The Reactor Building SPING is scheduled to be restored on Friday, January 16.

"This event is reportable per 10CFR50.72(b)(3)(xiii) since the maintenance activity affects classification and assessment.

"The NRC Resident Inspector has been notified."

Event Text

DEGRADED SECONDARY CONTAINMENT DIFFERENTIAL PRESSURE

"At 1939 [EST] on January 12, 2015, Nine Mile Point Unit 2 entered Tech Spec 3.6.4.1 when secondary containment was declared inoperable due to secondary containment differential pressure being above the Tech Spec Surveillance Requirement of -0.25 inches vacuum water gauge. This condition is related to sustained high winds. At 1956 on January 12, 2015 the differential pressure was restored, the secondary containment was declared operable and the Tech Spec 3.6.4.1 exited.

"Secondary containment being inoperable is a 8-hour report for 10 CFR 50.72(b)(3)(v)(c), 'Any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident'.

"The NRC Resident Inspector has been notified."

The licensee notified the New York Public Service Commission.
