Four specific relief requests were submitted for the third 10-year ISI interval, for which the code of record was the 1998 Edition, through the 2000 Addenda of ASME Code,Section XI. In particular, per Relief Request 13R-11, relief was requested from the Code required essentially 100 percent volumetric examination coverage requirements applicable to the Pressurizer nozzle-to-vessel welds, ASME Section XI Category B-D, Item No. B3.1 10.
During its review of Relief Request 13R-11, the NRC staff determined that requests for additional information (RATs) were needed to complete its review of the relief request. Pursuant to electronic correspondence dated November 3, 2015, the NRC transmitted a list of RATs to Ameren Missouri in electronic form on November 12, 2015, and requested that responses be provided within 29 days.

10 CFR 50.55a states the requirements governing the use of Code Cases, as amended by Regulatory Guide 1.147, Revision 17, Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1, which accepts ASME Code Case N-460, Alternative Examination Coverage for Class 1 and Class 2 Welds. The code case provides clarification that the stated requirement for examination of essentially 100 percent of the weld length means greater than 90 percent coverage of the examination volume, or surface area, as applicable.
3.0 REQUEST FOR ADDITIONAL INFORMATION 3.1 For RR 13R-1 1, please identify the non-destructive examination procedure used in the subject ultrasonic examinations (e.g., ASME Code,Section XI, Appendix VIII; or Section V, Article 4; or other).
Response
The examination was performed in accordance with ASME Section V Article 4, as supplemented by Section XI Table 1-2000-1. (Reference Section XI Article 1-2400.)
Attachment to ULNRC-06266 Page 2 3.2 Please state the material of construction of the Pressurizer (PZR) nozzles contained in the table in RR 13R-11.
Response
The Pressurizer nozzle material is nominal 3 carbon steel with .25 SS ID clad.
3.3 The ilcensees enclosed inspection reports states that 0, 45, and 60 degree angles were used in the examinations of the subject PZR nozzles-to-vessel welds. Please fully clarify the wave modality and insonification angles used for each of the ultrasonic examinations of the PZR nozzle-to-vessel welds contained in RR 13R-7 1.
Response
To the extent practical, a 0-degree longitudinal wave examination was performed on the accessible examination volume. Also, 45- & 60-degree shear wave examinations were performed in two directions axial to the weld and in two directions parallel to the weld on the available examination volume.
