: Alan, I have almost completed my portion of the SE, but I have come across an issue that I have not seen addressed in any of the correspondence so far. I have not been involved since the beginning so I may have missed it. But here is the issue, 10 CFR 50.69 says that an applicant following the risk-informed approach can use an alternative treatment for repair/replacement (with the exception of fracture toughness).. Fracture toughness requirements of the original construction code are also required to be met in ASME Code Case N-662, which provides alternative repair/replacement requirements for items classified in accordance with risk-informed processes. The NRC conditionally approved this code case for Class 2 and 3 components in the last to revisions of Reg Guide 1.147. The fracture toughness requirement was also addressed in the STP 50.69-like exemption SE. So I think we will need ANO-2 to say they agree to meet the fracture toughness requirements of the original code as part of the alternative repair/replacement requirements to authorize the alternative. Again, sorry for the late identification of this issue. I stopped by your office and it did not look like you were in today that is the reason for this long email. Let me know if we need to have a phone call. | |||

RE: MD5250 R-I Treatment Alan, I believe we are going to be able to approve the treatment. However, I was asked to wait until after the February 4th, Commission meeting with NEI on Risk Informed, Performance Based Regulation prior to issuing anything. We have heard that NEI will be escalating to the Commission an issue related to treatment with regard to 50.69 applications which is closely related to this Risk Informed request from ANO and we don't want to issue anything that could be in conflict with whatever might come out of this meeting. If nothing big comes out of the Commission meeting the treatment part of the SE should be done by early next week I think. | RE: MD5250 R-I Treatment | ||
