Subject:
RE: NMP1 Revised Responses for Audit Questions 17 and 19 [Follow-up to AQ-18]
Date:
Wednesday, July 19, 2023 5:29:00 PM Matt, Ron, The NRC staff has two follow-up questions on the response to audit question 18:
- 1. The response part c or d did not provide any discussion why the high-confidence wind speed is used for the screenhouse, while the 3-second gust wind speed is used for all other structures.Explain why the screenhouse uses a different method than all other structures.
- 2. In Response part e, the uncertainty c calculation is not consistent with Equation 4-10 of EPRI 3002003107, where it shows r or u = (s 2 + d 2 + p 2)0.5, but not c.Provide justification for deviation from EPRI 3002003107.
Please let me know if you intend to address and include in your updated response.
- Thanks,
