Vogtle Electric Generating Plant Units 3 and 4 License Amendment Request 19-019 Staff Audit Discussion Topics March 6, 2020
- 1. In Draft Supplement (ERR), Enclosure 2, page 7 of 34, UFSAR Table 3H.5-3 Elevation 1353 to 137-0, Note 4, required area of steel listed is 3.09 in-sq./ft. However, the staff could not find in the table. Is this a typo or correction to the table value of 3.08 in-sq./ft?
The value 3.09 in-sq/ft is also listed in the Enclosure 1, pages 8 and 16 of 42.
- 2. In Enclosure 2, page 4 of 34, Table 3.8.5-3, Note 5 lists Fig. 3.8.5-2, Sheets 3 to 6. The staff noted that in UFSAR Rev. 8 there is only one sheet associated to the Figure 3.8.5-2. Should the draft supplement reference Figure 3.8.5-3, Sheets 3 to 7?
- 3. On Table 3H.5-9, Sheet 1 and Sheet 2a of 3, the staff has confusion of interpretation of applied tolerance on the tables last column and Note 1. Please clarify intent of the tolerance in both places.
- 4. Informal Question to SNC: In response to staff audit questions dated January 29, 2020 (ADAMS Accession No. ML20029F008), UFSAR Table 3H.5-9 was revised to accurately reflect values from calculation APP-1278-GEF-084, Rev. 0. In the response (RFI APP-GW-GF-938), the applicant noted that an extended review had been performed on UFSAR Tables 3H.5-9 and 3H.5-15 which led to additional changes to the tables to reflect values from the latest calculations. It is unclear to the staff if an extent of condition review was conducted on the other UFSAR tables associated with LAR 19-019 that may also need to be updated to reflect the latest calculations.
