2R18 Final WOL Examination Report Page 1 of 56 2R18 FINAL WELD OVERLAY (WOl) EXAMINATION REPORT The information in the balance of this document is submitted pursuant to the provisions of Section 4.3.1. Required Activities, of the NRC approved Alternative Request RR-89-61, Revision 1. for Millstone Power Station Unit 2 (MPS2), Reference ADAMS Accession No. ML081150692. The required information includes the inspection results for new WOLs to four nozzle to safe end welds, including their respective adjacent stainless steel safe end to elbow or pipe weld. No additional weld overlays were performed during Refueling Outage 18 (2R18). 2-inch Cold Leg Charging Line Inlet Nozzle BCH-C-1001 12-inch Hot Leg Shutdown Cooling Outlet Nozzle BSD-C-2001 12-inch Hot Leg Surge Line Nozzle BPS-C-1001 12-inch Cold Leg Safety Injection Nozzle BSI-C-2001 Applicable pages for component descriptions in the report are as follows: WOL Component Description Applicable Pages in Final Report RCS Charging Inlet (BCH-C-1001) Pages 2 -25 RCS Shutdown Cooling (BSD-C-2001) Pages 26 -35 RCS Surge (BPS-C-1 001) Pages 36 - 45 RCS Safety Injection (BSI-C-2001) Pages 46 - 56 Level III Inspector Reviewer Comment Regarding 2R18 Examination Data Reports: The Inservice Inspection (lSI) examination volume to be examined upon completion of the weld overlay consists of the outer 25% of the underlying base material plus the full thickness of the overlay material extending 1/2 inches from the weld toe on each side of the weld. As has been described by provisions of the Alternative Request RR-89-61. Revision 1 for Millstone Power Station Unit 2, the current Appendix VIII, Supplement 11 examination procedures are not qualified to examine the outer 25% of the underlying cast stainless steel safe-end. For weld overlays of welds with cast stainless steel safe-ends, the cast stainless steel material is examined using the Appendix VIII. Supplement 11 qualified procedures as a best effort examination. The examination coverage is reported as the amount of volume examined of qualified material in accordance with the examination procedure. The cast stainless steel volume (remaining volume) is examined as a best effort examination and documented on the coverage calculation sheets of the applicable data package.

- Value from previous data The PSI examination of the weld overlay material was condUcted in one zone which was 11.61" width X 0.9275 deep - (8.02 XO.33I2) " 9.78 Sq inches. The clrcumferentlal scanning direction was limited on the nozzle end for an area of 0.67" width X 0.46" deep" 0.308 Sq Inches. Each clre scan Is assigned a weight factor of 0.25. The limitation divided by the lotal materia! mulitlled by 0.5 weight faclor provides examination coverage of 98.4%,
The lSI examination of the OM weld overlay and X T of the Base malerial was conducted in one zone whIch 1+1.53" wide X (0.9275' + 0,355") deep" 3.24 5q inches for the entire OM circumference. Due to the lack of a qualified examination method ror cast stainless steel there Is an examination IImltation of 0.355" X 0,60" + (0.20* X 0.355" 12) which Is aqualto 0.213 Sq inches. The limitation divided by the total material provlde$ examination coverage of 93.4%.

T of the Base material was conducted in one zone which 1+1.79" wide X (0.98" + 0.375 j deep - <<1+1.79) X (0.2912>> Sq in) '" 3.38 Sq inches for the entire DM circumference. Due to the lack of a qualified examination method for cast stainless steel there is an examination Umitatlon of 0.375" X 0.50" + (0.40" X 0.375" 12) which is equal to 0.263 Sq inches. The limitation divided by the total material provides examination coverage of 92.2%.
The lSI examination of the SS weld overlay and Y. T of the Base material was conducted In one zone which 1+1.27" wide X (0.0.955" + 0.3125) deep - <<1 +1.27) X (0.2912>> = 2.55 Sq inches for the entire SS circumference, Due to the lack of a qualified examination method for cast staInless steel there Is an examination limitation of 0.3125" X 0.50" which is equal 10 0.156 Sq inches. The Imitation divided by the total material provides examination coverage of 93.9%. The examination of the cast stainless material was performed as a "best effort" using current technology.
