Revised D-RAI 2.3A.4.5-2 Attachments: D-RAI 2.3A.4.5-2.doc Mike and company, During the telephone conference call on 12/17/08 to discuss the draft RAIs that were sent to you on 12/12/08, the staff agreed to reword D-RAI 2.3A.4.5-2 to accurately reflect the methodology described in the LRA.

Attached for your review is the first part of the reworded D-RAI. We are still working on the second part of the D-RAI and hope to send you that on Monday. Please let me know if you require a phone call to discuss the reworded D-RAI. The required staff will be available on Monday and Tuesday.

Thanks, Kim 1

D-RAI-2.3A.4.5-2 (Unit 2) a) In LRA Section 2.3.4.5 the applicant describes systems not described elsewhere in the application credited for mitigating the consequences of a Unit 2 fire event in the auxiliary feedwater (AFW) room. Each system listed has the following intended function: to support safe shutdown in the event of a fire in the auxiliary feed pump room (10 CFR 50.48) function in accordance 10 CFR 54.4(a)(3). The applicant states no LRA drawings are provided based on the intended function of supporting safe shutdown in the event of a fire in the auxiliary feed pump room. However, the applicant states in LRA Section 2.2 Components subject to aging management review are highlighted on license renewal drawings, with the exception of components in scope for 10 CFR 54.4(a)(2). Since the structures and components that support mitigating the consequences of a fire event are in scope in accordance with 10 CFR 54.4(a)(3) and subject to an AMR in accordance with 10 CFR 54.21(a)(1), then the components should have been highlighted on license renewal drawings. However, the applicant did not highlight the components or flowpaths needed to support this event. In addition, the applicant did not, in accordance with 10 CFR 54.21(a)(1), identify and list the structures and components that are subject to an AMR. Therefore, based upon the information provided in the LRA, the staff was not able to verify which components are included in scope to perform the stated function and are subject to an AMR.

For each system identified in LRA Section 2.3.4.5, the staff requests the applicant to a) identify the system support function for the AFW pump room fire event, b) clearly identify the portions of the systems flow paths that support these functions that are subject to an AMR, and c) identify the portions of these flow paths that are not already in scope for 10 CFR 54.4(a)(2)
