FSWOL 14-day transmittal Michael Markley, This is to inform you of (1) the examination results of the weld overlays and (2) any repairs to the overlay material and/or base metal and the reason for the repair within 14 days after the completion of the ultrasonic examination of the weld overlay installations.
The ultrasonic examinations of the weld overlay installations in Unit 2 were completed on May 10, 2008. The nine full-structural weld overlays (FSWOL) on the Unit 2 Pressurizer Surge, Hot Leg Surge, Hot Leg Shutdown Cooling (2), Pressurizer Spray and Pressurizer Safety/Relief Nozzles (4) were examined using the liquid penetrant (PT) and phased array ultrasonic examination (UT) methods as required by Relief Request 36. The UT examinations were performed using SIs PDI qualified ultrasonic examination procedure and examiners. One laminar indication was identified in the Pressurizer Safety/Relief Nozzle, SRV 202 and was dispositioned as acceptable. Since no unacceptable flaw indications were detected in the overlays, no repairs were needed.
This email is intended to be the 14-day notification in accordance with the commitment in our February 8, 2007, letter. A written submittal containing the inspection results will be provided to the NRC within 60 days after startup following the inspections, as committed in our letter no. 102-05640, dated January 31, 2007, "Mitigation of Alloy 600/82/182 Pressurizer Butt Welds." Also, since the welds subject to the March 15, 2007, confirmatory action letter have been mitigated and inspected in Unit 2, we are planning to discontinue the enhanced leakage monitoring when we start up Unit 2.
