Mr. James P. O'Reilly, Director U. S. Nuclear Regulatory Commission Region II 101 Marietta Street, Suite 3100 slanta, Georgia 30303 Re: RII:JPO Catawba Nucl tation Docket Nog. 50-413 and 50-414

Dear Mr. O'Reilly:

In response to your letter of April 4, 1980 which transmitted IE Bulletin 79-03A, we wish to advise that a review of Catawba Nuclear Station's piping specifications has beca conducted. Duke Power Company has not used SA-312, A-312, Type 300 Series fusion welded pipe in safety-related systems at greater than 85 percent of Code allowabic pressure stresses. No future use above this limit is planned.

Ve y truly yours, g '
