Title	Degraded Condition of Leakage from Pump Lower Seal Weld
Event Description	On 11/13/15 at 1745 EST, Unit 1 drywell entry was performed during an unplanned Unit 1 outage. The licensee identified leakage from a weld on the 3/4 inch lower seal vent piping connected to the 1B reactor recirculation pump lower seal area. The location is within the reactor recirculation loop isolation valves, therefore isolable from the reactor vessel. The piping is ASME Class 2 and is a reactor coolant pressure boundary. The reactor was in mode 3 at the time of discovery. Control Room determined at 2110 EST on 11/13/15, that requirements for 10CFR50.72(b)(3)(ii)(A) were not met. This event is being reported as a degraded condition pursuant to 10CFR50.72(b)(3)(ii)(A). The Licensee notified the NRC Resident Inspector.
