D-RAI 3.4.2-2:
By letter dated January 27, 2009, Entergy responded to RAI 3.4.2-1, and provided clarifying details regarding the passive, long-lived component types, materials, environments, aging effects and aging management programs for systems, structures and components that support the auxiliary feedwater (AFW) pump room fire event at Indian Point Nuclear Generating Unit No. 2 (IP2) that were not already within the scope of license renewal for 10 CFR 54.4(a)(1) or (a)(2).
The staff reviewed the response and determined that the systems contain passive, long-lived components made of materials that when exposed to the stated environments may experience aging effects as described in the GALL Report, which must be managed during the period of extended operation in accordance with 10 CFR 54.21(a)(3).
By letter dated May 1, 2009, Entergy submitted a revised commitment list which included a new commitment (Commitment 39) to install a fixed automatic fire suppression system for IP2 in the AFW pump room which would make the suppression configuration of the room similar to that of the AFW pump room at Unit 3.
Because the planned installation is not yet part of the current licensing basis, the staff cannot make a finding consistent with the requirement in 10 CFR 54.29(a). Therefore, the staff requests that the applicant provide information to demonstrate that the effects of aging will be adequately managed so that the intended function(s) will maintained consistent with the CLB for the period of extended operation as required by 10 CFR 54.21(a)(3). Specifically, the staff requests that the applicant list all aging effects and the AMPs needed to manage the aging effects for the component types provided in the January 27, 2009 letter.
