LR-N21-0039 April 30, 2021 United States Nuclear Regulatory Commission Attention: Document Control Desk Washington, D.C. 20555 Hope Creek Generating Station Renewed Facility Operation License No. NPF-57 NRC Docket No. 50-354 Subject Deviation from EPRI document 33002012244 Inspection Requirements

Reference:

EPRI document 33002012244, Nondestructive Evaluation:

Guideline for Conducting Ultrasonic Examinations of Dissimilar Metal Welds, Revision 3 PSEG - Hope Creek Letter LR-N15-0128 (ML15187A202), Deviation from EPRI document 3002000091 Inspection Requirements EPRI (Electric Power Research Institute) document 33002012244, Nondestructive Evaluation:

Guideline for Conducting Ultrasonic Examinations (UTs) of Dissimilar Metal Welds, Revision 3, requires an encoded UT examination. The requirement for Hope Creek to comply with EPRI 33002012244 is based on an industry commitment to follow the guidelines of NEI 03-08 for "needed" requirements.

Performance of EPRI document 3002012244 Appendix A Requirement for Encoded Examinations for two IGSCC susceptible welds (as directed by Needed Requirement Section 3.2) is not completed. This is a revision to a previously submitted deviation with the main change being the date of the encoded examination being H1R29.

The reason for the deviation is that performance of the encoded examinations involves work in a high dose area, and the dose and time constraints make performance in H1R23 not possible. With non encoded exams completed in H1 R23. the next BWRVIP-75-A required examination for these welds is H1R29 This correspondence discusses the deviation from the requirement to perform the examinations.

A technical evaluation of the deviation from the EPRI document 33002012244 inspection requirements was performed. The evaluation determined that the H1R19 examinations were performed using a qualified technique, by qualified personnel, concluding that no recordable indications exist within 100%

of the exam volume. The results of the H1R19 examinations are consistent with the results of the H1R15 examinations. Both welds were examined in H1R15, with no recordable indications noted, by manual phased array UT technique qualified to the requirements of ASME Section XI Appendix VIII,

LR-N21-0039 Page 2 Supplement 10. The H1R23 examinations are being performed using phased array UT methods.

Inspection of the welds, after H 1R23, is not required until H 1R29.
