Dear Mr. Johnson:

On June 9,1986, we verbally notified you of a reportable item involving the scope of plant modifications resulting from the project's pipe support reverification program (see TXX-4844). This is a follow-up interim report on a reportable item under provisions of 10CFR50.55(e). We have submitted an interim report logged TXX-6042, dated October 15, 1986.

The continuing engineering evaluation has not identified any additional instances which are considered reportable pursuant to 10CFR50.55(e). The attached list shows the support modifications issued to date. The evaluation is continuing and we anticipate submitting our next report by January 9, 1987.

Very truly yours, (WN W. G. Counsil BSD/amb c - NRC Region IV (0 + 1 copy)
