          FOLLOW-UP PART 21 REPORT (SSH 960004)

Ref: (a)  Gary J. Taylor to Document Control Desk, RC-96-0157
          dated June 17, 1996.
     (b)  David D. Molitoris, Westinghouse, to R. J. Waselus, SCE&G,
          CGE-96-029 dated November 11, 1996.

South Carolina Electric and Gas Company (SCE&G) submits the following
follow-up response in accordance with 10CFR21.21 (a)(2) as a final report
of an identified defect determined not to be potentially associated with
a substantial safety hazard.

Per reference (a), we contacted Westinghouse, the original equipment
manufacturer, to evaluate the the nozzle weld defects in the Chemical and
Volume Control System connections at the reactor coolant pump seal
injection line nozzles and Component Cooling Water System connections at
the reactor coolant pump thermal barrier heat exchanger inlet and outlet
nozzles for 10CFR21 reportability.

Westinghouse has determined that a Substantial Safety Hazard (SSH)
reportable under 10CFR21 does not exist based on the following:

1.   The Westinghouse safety evaluation on this issue has determined that
     the condition is non-safety related per reference (b).

2.   Westinghouse has had only about 10 reported problems (including the
     6 from VCSNS) in the 1200 nozzles that have been in service for up
     to 29 years.  (Reference (b).

VCSNS initially determined that the problems associated with the RCP Seal
Injection/CCW Nozzle Welds were a potential SSH reportable under 10CFR21;
however, based on the Westinghouse evaluation, no SSH exists.

                NUCLEAR EXCELLENCE - A SUMMER TRADITION!
