Title	Degraded Condition Discovered on Pressurizer Nozzle Weld During Testing
Event Description	On February 5, 2014, during planned inspections, an ultrasonic examination performed on weld PCS-6-PRS-1C1-1 (RV-1041) revealed two axial indications in the root area of the weld. The weld containing the indications is the nozzle to safe end dissimilar metal weld on the flange for pressurizer safety valve RV-1041. These two indications do not meet applicable acceptance criteria under ASME,Section XI, IWB-3600, 'Analytical Evaluation of Flaws,' or ASME Section Xl, Table IWB-3410, 'Acceptance Standards,' and will require a repair or replacement activity in order return the weld to an acceptable condition. The plant was in cold shutdown at 0% power for a planned refueling outage at the time of discovery. Replacement or repair actions will be completed prior to plant startup from the outage. This condition has no impact to the health and safety of the public. The licensee notified the NRC Senior Resident Inspector. This report is being made in accordance with 10 CFR 50.72(b)(3)(ii)(A), since indications were found that did not meet acceptance criteria referenced in ASME Code,Section XI.
