Subject:

Catawba Nuclear Station Docket Nos. 50-413 and 50-414

Dear Sir:

On December 7,1987. Duke Power Company submitted a steam generator tube rupture analysis for Catawba Units 1 and 2 in accordance with License Conditions 16 and 10 of Facility Operating Licenses NPF-35 and -52, respectively. A proposed amendment to the Technical Specifications, which would add requirements for the steam generator PORV's, was submitted on December 4, 1987, in response to the i

same license conditions. By letter dated December 25, 1987 Duke advised the NRC that the proposed Technical Specification and the supporting analysis would be revised in order to justify a less restrictive action statement for the steam generator PORV's. While doing the reanalysis, questions arose relating to the North Anna tube rupture event that had to be considered. By letter dated March 29, 1988, we indicated the analysis and Technical Specification change would be submitted by May 16, 1988. As a result of further reviews necessary, the analysis and Technical Specification change will be submitted by June 21, 1988, t

Very truly yours, g%
