ENCLOSURE 492.11 Table 4.4-1 of the Vogtle FSAR quotes the thermal and hydraulic data of SNUPPS to demonstrate that the Vogtle thermal and hydraulic data are similar to those of SNUPPS. However, the quoted SNUPPS data are different from the data of Table 4'.4-1

. of the current SNUPPS FSAR (e.g. coolant flow,' coolant tanperatures, and pressure drop are different).

Explain the discrepancies between the two data sets. >

s 4

Should you determine that the quoted SNUPPS data in Table 4.4-1 of the Vogtle FSAR are no lqnger valid, explain the reason (e.g.,

design changes) why the values of the Vogtle thermal and hydraulic data are different from those of SNUPPS.
