Dear Mr. Johnson:

On September 18, 1985, we verbally notified your Mr. T. Westerman of a deficiency involving errors identified in checking routines of computer i

program P Delta STRUDL 0385.

The program is used by an engineering i

contractor in the analysis of cable tray and conduit supports for Unit 2.

i We have submitted interim reports logged TXX-4614 and'(XX-4590, dated j

November 7, 1985, and October 10, 1985, respectively.

i Computer routines for approximately 1,000 of 3,800 affected calculation packages potentially affected by the program errors have been rerun.

This sample has not identified a single support where the errors have had an adverse effect on the integrity of the cable tray supports.

The issue is j

not reportable under the provisions of 10CFR50.55(e). Records supporting this determination are available for your inspectors to review at the CPSES site.

Very truly yours,.
