Serial No. 13-497A Docket No. 50-336 Attachment 1, Page 1 of 7 By letter dated April 9, 2013, Dominion Nuclear Connecticut, Inc. (DNC) requested NRC approval of an alternative to the requirements of American Society of Mechanical Engineers (ASME) Code Case N-770-1, "Alternative Examination Requirements and Acceptance Standards for Class 1 PWR Piping and Vessel Nozzle Butt Welds Fabricated With UNS N06082 or UNS W86182 Weld Filler Material With or Without Application of Listed Mitigation Activities," as amended by 10 CFR 50.55a(g)(6)(ii)(F).
Specifically, DNC requested approval of Alternative Request RR-04-15 to allow use of a limited one-sided ultrasonic examination technique for Millstone Power Station Unit 2 (MPS2). In a letter dated August 22, 2013, the Nuclear Regulatory Commission transmitted a request for additional information (RAI) to DNC related to the alternative request. However, in a discussion between DNC and the NRC on September 16, 2013, it was determined that the initial RAI would be superseded. In a letter dated October 8, 2013, the NRC transmitted the replacement RAI. This attachment provides DNC's response to the NRC's RAI.
Question 1 In order to evaluate the proposed alternative, the NRC staff requires the details of the Appendix VIII-qualified inspection procedure that is to be used on the welds described in RR-04-15 during the Spring 2014 outage at Millstone Power Station Unit 2.
Specifically, the following items are requiredto evaluate the proposed alternative:
- a. Provide the inspection angles that are to be used by the phased array probe to insonify the welds during the examination.
- b. Provide the specific inspection angles that are to be used to calculate coverage.
- c. Provide the Performance Demonstration Qualification Summary (PDQS) describing the procedure and any limitations placed on the ASME Code Section X1, Appendix VIII-qualified procedure.
- d. Describe the modifications, if any, made to the procedure using the site-specific mockup process.
DNC Response
- a. Procedure LMT-10-PAUT-007, "Fully Encoded Phased Array Ultrasonic Examination of Dissimilar Metal Piping Welds", will be used to perform these examinations, to the extent possible. The following table describes the ultrasonic beam angles used to perform the examinations in accordance with this qualified procedure.
Serial No. 13-497A Docket No. 50-336 Attachment 1, Page 2 of 7 Flaw Scan Type Type of Examination Refracted Angles and Orientation Modes of Propagation Circumferential Axial Raster Detection and Length 300, 37.50, 450, 52.50, and Sizing 600 refracted longitudinal wave Circumferential Axial Raster Detection and Length 450, 52.50, and 600 Sizing refracted shear wave Circumferential Axial Raster Depth Sizing 30-, 450, 520, 600, and 700 refracted longitudinal wave Axial Circumferential Detection and Depth 250, 350, 450, and 550 Raster Sizing refracted longitudinal wave, skewed -30' to 30' with a 2.50 resolution
- b. The examination coverage calculations are based upon the demonstrated flaw detection beam angles identified in the table above. Effective examination coverage is claimed when at least one of the demonstrated beam angles covers the examination volume. Examination coverage may be provided by a single beam angle or a combination of beam angles. The examination plan will be optimized to cover the examination volume with as many of the qualified beam angles as possible.
- c. The Performance Demonstration Qualification Summary (PDQS) for procedure LMT-10-PAUT-007 is provided in Attachment 2.
Procedure LMT-10-PAUT-007 is applicable to the fully encoded phased array ultrasonic examination of full penetration, wrought dissimilar metal piping welds including the adjacent base material. Examinations are conducted from the outside surface using the contact method. This procedure is also applicable to welds which are susceptible to primary water stress corrosion cracking (PWSCC) and intergranular stress corrosion cracking (IGSCC). This procedure is applicable to dissimilar metal welds 1.5 inches and greater in diameter that range in thickness from 0.210 to 6.50 inches.
This procedure is qualified for dissimilar metal weld examinations as follows:
- 1) Detection, length and through-wall sizing of circumferentially-oriented indications where single or dual side access is available.
- 2) Detection and through-wall sizing of axially-oriented indications.
Serial No. 13-497A Docket No. 50-336 Attachment 1, Page 3 of 7 This procedure is not qualified for:
- 1) Length sizing of axially-oriented indications regardless of location, however, as described in the procedure, the technique used for sizing of circumferential flaws may be used.
- 2) Examinations where the ultrasound is required to propagate through an adjacent austenitic weld prior to impinging on the dissimilar metal weld examination volume.
This procedure has not demonstrated techniques to:
- 1) Size embedded fabrication flaws.
- 2) Detect length or depth size flaws in cast austenitic materials.
The following limitation has been placed upon this procedure as part of the demonstration process:
- 1) Axial flaw depth sizing is limited to situations where the search unit passes entirely over the indication to be sized.
- d. The site-specific mockup process has not been used to modify the examination procedure for these welds. The Performance Demonstration Initiative (PDI) procedure demonstration sample set, used for the procedure demonstration, contains samples representative of the configurations of these welds.
Question 2 Provide tables showing the total expected inspection coverage and diagrams showing the expected inspection coverage that will be for both the obstructed and unobstructed regions of the welds using the procedure described in Question 1.
DNC Response The following table summarizes the expected examination volume coverage for each of the welds. The impact of the obstructed regions of the welds has been minimized through the procedure development and qualification process to maximize effective coverage of the examination volume. The four welds representing the pump suction dissimilar metal welds are similar in configuration and the expected examination coverage is illustrated in Figure 1. The four welds representing the pump discharge dissimilar metal welds are similar in configuration and the expected examination coverage is illustrated in Figure 2. These coverage estimates are based on the anticipated coverage through the application of the demonstrated procedure, the known
Serial No. 13-497A Docket No. 50-336 Attachment 1, Page 4 of 7 field configurations, and equipment modifications. The actual coverage obtained from these examinations may vary based on unknown conditions or unforeseen limitations.
The examination volume coverage summary has been categorized based on the following: 1) materials demonstrated through the Appendix VIII process (alloy 600 and carbon steel base material) and 2) the cast stainless steel material. Although not demonstrated through the Appendix VIII process, the cast stainless steel base material will be examined to the extent possible with the Appendix VIII, Supplement 10 demonstrated procedure.

Serial No. 13-497A Docket No. 50-336 Attachment 1, Page 7 of 7 Question 3 Appendix A of the 2013 report by the Electric Power Research Institute "Nondestructive Evaluation: Guideline for Conducting Ultrasonic Examinations of Dissimilar Metal Welds, Revision 1" contains a flow chart detailing when encoded examinations should be used for dissimilarmetal welds. This guidance on the use of encoded scanning is an NEI-03-08 "Needed"requirementfor the first inspection after January 2014. Based on the inspection plans and the EPRI guidance, identify which welds will be inspected using encoded and which will be inspected using non-encoded techniques?
DNC Response In accordance with the guidance provided in Appendix A of the 2013 Electric Power Research Institute report, "Nondestructive Evaluation: Guideline for Conducting Ultrasonic Examinations of Dissimilar Metal Welds, Revision 1," encoded ultrasonic examination technology is planned to be applied to each of these welds to the extent possible. Any areas of limited examination coverage due to encoded equipment restrictions identified during the examinations would be supplemented with non-encoded phased array ultrasonic examination techniques to maximize examination coverage.
