RE: Davis Besse - RAI Responses Hi Bryce:

I spoke with Abdul and Ill be scheduling the teleconference call to be early next week. Abdul will be sending me an e-mail summarizing his concerns on the RAI responses so I can forward them to the applicant and they can be prepared for the teleconference call. Can you do the same for yours?

Davis Besse - RAI Responses 1

I will like to have a telephone call with the applicant about RAI B.22-1 thru B.22-4 responses. I think other persons in RASB will also like some clarifications on other structural RAIs.

Can you please arrange a conference call. I will be out of office from Tuesday afternoon thru Thursday this week.

Davis-Besse SMP RAI Concerns RAI B.2.39-1 Part 1: We need more information on the core bore results and how they concluded there is no concern with the structural integrity. Applicant should be prepared to discuss the report referenced in the RAI response.

Part 2: We need more details in the commitment, specifically what will be done if the applicant cannot stop the leakage or the leakage begins again at a later date (e.g.

core bores, more frequent inspections, etc.).

RAI B.2.39-2 This should be a two-part solution: 1) concrete bores to verify past leakage did not degrade walls, 2) future actions to ensure leakage does not occur again. The applicant addressed part 1; however, they did not adequately address part 2. The applicant should commit to take actions to ensure the leak-chase system remains operable during the PEO (e.g. boroscopic inspections at an technically justifiable interval).
