Gentlemen:

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 validation program (see TXX-4844). This is a follow-up interim report on a reportable item under provisions of 10CFR50.55(e). Our latest interim report logged TXX-6507 was submitted on June 12, 1987.

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 November 20, 1987.

Very truly yours, W. G. C unsil
