DESIGN INf0RMA110N FOR THE DELTA 75 REPLACEMENT STEAM GENEiT10R (REM 6000)

On January 9, 1992, South Carolina Electric & Gas Company (SCE&G) met with the NRC to discuss the Virgil C. Summer Nuclea. Station (VCSNS) Steam Generator Replacement Prc.. ;t. At that time, the NRC requested that SCE&G submit information related to the design and fabricat' n of the Delta 75 replacement steam gener tor. The enclosed WCAP-13F Westinghouie Delta 75 i Steam Generator Desian c.sd Fabrication Information .ne Viroil C. Summer

[ Nuclear Station, provides a comparison of the current lodel 0-3 versus the Delta 75 design, performance, and operational characteristics. In addition, the Delta 75 materials of construction as well as manufacturing, weldir.g. and heat treatment processes are briefly described. Please note that this WCAP describes the Delta 75 design to data. Some minor changes may be made during design finalization and fabrication. If the NRC requires additional information on the Delta 75, it may be beneficial to meet with SCE&G and Westinghouse at the Westinghouse-Pensacola manC acturing facility. This would allow for a more detailed presentation / discussion of the Delta 75.
