[External_Sender] LAR-17-028 RAI Response Supplement On December 15, 2017, Southern Nuclear Operating Company (SNC) provided a response [ML17349A856 (public version) and ML17349A857 (non-public version)] to NRC Staffs request for additional information (RAI) [ML17305B331]

regarding SNC license amendment request (LAR)-17-028 [ML17230A365].

In the RAI response, SNC made statements regarding efforts being undertaken to optimize reinforcement in the walls and floors presented in Tables 1 and 2 of the RAI response. Those optimization statements are beyond the scope of the LAR, and are not necessary to answer the RAIs. Therefore, these statements may be disregarded. The paragraphs which follow Tables 1 and 2 in Enclosures 3 and 4 of the RAI response provided in ND-17-1975 should be considered revised to remove these statements as shown below (red strikethrough indicates deleted text):

Paragraph following Table 1 in Enclosures 3 and 4 The required area of reinforcement of Table 1 is given as a peak value over the entirety of the floor slab. As the reinforcing placement differs throughout the floor slab, the location with the largest interaction ratio increase for a given direction is presented. Note that optimization efforts, independent of this license amendment request (LAR), were recently undertaken to reduce the total area of reinforcement in the floor slab and reduce congestion and improve constructability, with areas as provided in Table 1. In all cases, the maximum interaction ratio of the floor slab remains below 1.0 and is acceptable.

Paragraph following Table 2 in Enclosures 3 and 4 The required area of reinforcement of Table 2 is given as a peak value over the entirety of the wall elevation. As the reinforcing placement differs throughout the wall elevation, the location with the largest interaction ratio increase for a given direction is presented. Note that optimization efforts, independent of this LAR, were recently undertaken to reduce the total area of reinforcement in the presented elevation of the wall to reduce congestion and improve constructability, with areas as provided in Table 2. In all cases, the maximum interaction ratio of the wall elevation remains below 1.0 and is acceptable.
