supplied by Westinghouse.

SCE&G has taken the following actions:

All nine (9) nozzles were inspected. Six (6) nozzles revealed indications of cracking and were repaired using the TIG welding process, and satisfactorily reinspected.

The original equipment manufacturer has been contacted.

SCE&G expects to complete the evaluation of 10CFR21 reportability prior to September 1,1996.
