[External_Sender] Minor comment re: NRCs Safety Evaluation for the Surry Unit 2 4th Interval Limited Exam Relief Requests Date:
Tuesday, February 28, 2017 5:13:23 PM Hey Karen,
We have reviewed the NRC letter dated 2/17/17 that provided the NRCs Safety Evaluation for the Surry Unit 2 4th Interval Limited Exam Relief Requests and did not identify any technical concerns or issues. However, we did note a few administrative discrepancies in the last paragraph of Section 4.0, Conclusion, that I wanted to provide for your information. The identified discrepancies are highlighted below, as well as the correction noted in blue and contained in brackets to the right of the highlighted text. While these discrepancies occurred in the Conclusion section of the SE, the correct information was included and discussed in the specific relief requests contained within in the body of the letter.
4.0 CONCLUSION
As set forth above, the staff determined that granting relief pursuant to 10 CFR 50.55a(g)(6)
(i) is authorized by law and will not endanger life or property, or the common defense and security, and is otherwise in the public interest given due consideration to the burden upon the licensee that could result if the requirements were imposed on the facility. Furthermore, the staff concludes that the licensee's examinations were performed to the extent possible and provide reasonable assurance of the structural integrity of the subject pressurizer welds and nozzle inside radius, and piping integral welded attachments at Surry, Unit 2. Accordingly, the staff concludes that the licensee has adequately addressed all of the regulatory requirements set forth in 1 O CFR 50.55a(g)(6)(i). Therefore, the NRC staff grants the following relief requests for the fourth ten-year ISI interval of Surry, Unit 2, which commenced May 10, 2004, and ended, as extended, on May 9, 2015.
LMT-R01 Category R-A, Class 1 Stainless Steel Pipe Risk Informed Welds LMT-SS01 Category C-F-1, Class 1 Stainless Steel Pipe Welds {Should be Class 2, not Class 1}
LMT-CS01 Category C-F-2, Class 1 Carbon Steel Pipe Welds { Should be Class 2, not Class 1}
LMT-P01 Category C-F-1 and R-A Preservice Pipe Welds LMT-C01 Category 8-8, Pressurizer Shell to Head Section {Should be Category B-B}
LMT-C02 Category 8-D, Pressurizer Nozzle Inner Radius Section {Should be Category B-D}
LMT-C03 Category C-C, Main Steam lntegral Attachment H001-1
