COMANCHE PEAK STEAM ELECTRIC STATION DOCKET NO. 50-445 UPS INVERTERS SDAR: CP-86-30 (INTERIM REPORT)
Dear Mr. Johnson:
On April 18, 1986, we verbally notified your Mr. R. Hall of a deficiency involving anomalies observed in Class 1E inverters supplied by Elgar Corporation of San Diego. This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e). These inverters are installed in the AC distribution system in Unit 1.
We are continuing our evaluation and anticipate submitting our next report by June 27, 1986.
Very truly yours, i
