Ms. E. G. Adensam, Chief Licensing Branch No. 4

Subject:

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

Dear Mr. Denton:

Please find attached our responses to NRC requests for information dated June 4, 1985 concerning Generic Letter 83-28.

These responses address Items 4.2.1 and 4.2.2 which have to do with reactor trip system reliability and trending aspects of the preventative maintenance program for reactor trip breakers.

This submittal parallels portions of our letter of May 24, 1985, in which these items were addressed for McGuire Nuclear Station. Our responses are essentially the same for both stations.

Very truly yours, k
