[External_Sender] Minor comment re: NRC's 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 NRC's Safety Evaluation for the Surry Unit 2 4 th 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.
