i McGuire Nuclear Station response to Generic Letter 88-03 Steam Binding of Auxiliary Feedwater Pumps. February 17, 1988, stated that the licensee would provide continuous monitoring of auxiliary feedwater piping to detect the formation of steam voids that could prevent the auxiliary feedwater pumps from performing their intended safety i function.

Contrary to the above, continuous monitoring to detect steam voiding was not accomplished due to the installation of an incorrect type of resistance thermal detector (RTD) to provide accurate indication of auxiliary feedwater piping temperatures and activation of control room alarms when temperatures exceeded established administrative limits.

This condition was identified on August 1.1996.

Please provide to the U.S., Nuclear Regulatory Commission. ATTN: Document Control Desk,llashington, D.C. 20555 with a copy to the Regional i Administrator.
