Dear Mr. Keppler:

This item was originally identified to Mr. McGregor of your of fice on June 26, 1981, by Mr. W. Kacer of The Cleveland Electric Illuminating Company (CEI). Interim reports nn this subject were submitted July 24, 1981, and April 29, 1983.

This report contains a description of the deficiency, an an21ysis of safety implication, and the corrective action taken.

Description of Deficiency Due to irregularities in the plastic part used in the switch assembly, push-buttons in Bailey 720 Utility Station devices may stick in an open or closed position. This condition was identified to CEI by GE on May 13, 1981.

A defective device could cause a false operating signal to be transmitted during manual operation. This could result in the technical specifications being exceeded during a postulated plant event.
