A. The details of any age related degradation which caused the failure of the circulating water piping, pipe supports, and cooling tower cell. Include the results of the piping and pipe supports inspection and a description of the identified aging mechanism(s).

B. Indicate how the identified age related degradation has been considered, as pertinent operating experience, during license renewal scoping.

C. The potential affect on safety-related SSCs, of a similar piping or structure failure of the nonsafety-related cooling tower cells (and contained circulating water piping and pipe supports) which were not included within the scope of license renewal, including the affect of debris entering the cooling basin [10 CFR 54.4(a)(2)].

D. A conclusion and basis as to whether the scoping results documented in the license renewal application, which initially determined that nine of the eleven cooling tower cells were not within the scope of license renewal, are still valid.

RAI 2.4.4-2 Please provide the results of the review performed to determine the impact of.the circulating water piping, pipe supports, and west cooling tower cell (2-4) failures on license renewal scoping, screening, and applicable aging management programs. Please include the following:

A. A conclusion and basis as to whether the scoping results documented in the LRA, which initially determined that 9 of the 11 west cooling tower cells were not within the scope of license renewal, are still valid.

B. If found that the west cooling tower cells are within the scope of license renewal. Please provide the following:

I. The potential effect of a circulating water piping, pipe supports, or structural failure of the nonsafety-related west cooling tower cells (2-3 through 2-11), which were not included within the scope of license renewal, on safety-related systems, structures, and components (in accordance with 10 CFR 54.4(a)(2)). Include the potential effect of debris entering the deep basin beneath the cooling tower.

II. The details of any age related degradation which caused the failure of the circulating water piping, pipe supports, and west cooling tower cell. Include the results of the piping and pipe supports inspection related to the current failure and any previously performed, and a description of the identified aging mechanism(s).

C. Any impact on the aging management programs for circulating water piping, pipe supports, or cooling tower cells.

Discussion: The applicant indicated that the question is clear. The applicant also used the call as an opportunity to brief the staff on the design and operation of the cooling towers.
