Subject:

Catawba Nuclear Station, Unit 2 Docket Number 50-414 Withdrawal of Request for Relief Number 93-03 Relief Rcquest from Immediate Component Cooling Heat Exchanger 2B ASME Code Repair

Reference:

Letter from D.L. Rehn to NRC, same subject, dated November 15,1993 Gentlemen:

By copy of this letter, Duke Power Company is formally withdrawing the request for relief made

~ in the reference letter. The flaw in the Component Cooling (KC) Heat Exchanger 2B tube which resulted in the submission of the relief request was repaired on December 4,1993. The repair was performed following recent detection of an unforeseen change in the flaw. Hence, the relief rec.st is no longer necessary. It should be noted that the change in the flaw did not result in an increased leak rate through the flaw.

If you have any questions, please call L.J. Rudy at (803) 831-3084.

Very truly yours D.L. Rehn LIR/s 1300%
