Dear Mr. Johnson:
On April 10, 1986, we verbally notified your Mr. R. Hall of a deficiency involving a possible concern in that without full breaker / fuse coordination, portions of the CPSES damage study could be incorrect. This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e).
We have submitted an interim report logged TXX-4789, dated May 9, 1986.
We are continuing our evaluation and anticipate submitting our next report by August 29, 1986.
Very truly yours,
/
