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,. ;
