CP-87-54 (INTEPIM REPORT)
Gentlemen:
On July 31, 1987, we verbally notified your Mr. H. S. Phillips of a deficiency involving electrical design drawings which do not apparently implement FSAR requirements for Class 1E motor-operated valve motor starters.
The drawings do not provide the motor starter with thermal overloads connected only to alarms or thermal magnetic breakers to trip the starter for sustained locked motor conditions.
This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e).
We are continuing our evaluation of the impact of this issue upon the safety of plant operations.
We anticipate submitting our next report by November 6, 1987.
Very truly yours, 6
W. G. Counsil
