D-RAI 2.5-4 In license renewal application (LRA) Section 2.5, as clarified in LRA Amendment 3, dated March 24, 2008, the applicant included in the scope of license renewal the structures and components for one offsite circuit path (138 kV/Station Auxiliary Transformer circuit, the immediate access circuit). The applicant is requested to explain why the second offsite circuit (the delayed access circuit) path, from the first inter-tie with the offsite distribution systems at the Buchanan substations to the safety buses, was not included in the scope of license renewal. Specifically, the applicant is requested to explain why the components up to and including either 138 kV circuit breaker F1 or 345 kV circuit breaker F7 for IP2 and either 138 kV circuit breaker F3 or 345 kV circuit breaker F7 for IP3 were not included in the scope of license renewal.

Follow-up RAI 2: Open Item 3.0.3.2.15-1 The purpose of this follow-up request for additional information (RAI) is to request additional information and clarification to help the staff to understand the applicants May 1, 2009 response to Follow-up RAI 1 for Open Item 3.0.3.2.15-1. Specifically, the staff requests the following:

(a) In part (a) of the applicants response, Figures 1 through 4 do not clearly identify the flow path from the refueling cavity liner to the A, B, and C water exit locations. Therefore, please provide the following additional descriptive information:

(1) In an elevation view, cut through each of the exit locations A, B, and C, showing the horizontal and vertical dimension between the entry point through the liner and the exit location.

(2) In a plan view, one for each exit location, identify the circumferential traverse of the leakage, from the entry point through the liner to the exit location.

(b) The staff requests the applicant to provide the following additional information/clarification regarding the revised license renewal commitments in part (b) of the applicants response:

(1) The current remediation plan has targeted the 2014 outage for completion.

Please identify actions that will be taken if the remediation plan is unsuccessful.

(2) Identify the specific location and number of the concrete core samples (e.g., the three water exit locations) that will be removed and tested (i) during the upcoming 2010 refueling outage, and (ii) at 10 years into the extended period of operation (if a permanent solution for the leakage has not been achieved, in accordance with Entergys current remediation plan). Define the tests that will be performed, and the objective of each test.

(3) Please advise if the revised commitments in the applicants May 1, 2009 response include chemical analysis of the leaking water (i) during the upcoming 2010 refueling outage, and (ii) at 10 years into the extended period of operation.

Please identify the analyses that will be performed, and the objective of each analysis.
