LER ATTACHMENT - RO NO. 2-80-26 Facility: BSEP Unit No. 2 Event Date: February 25, 1980 During the 1980 Unit No. 2 refueling outage, several instruments were scheduled to be replaced with more reliable analog-type instrumentation.
Prior to the refueling outage, Carolina Power & Light Company contacted other utilities which had already made this conversion to learn of any problems they experienced.
From these conversations, it was decided that a thorough bench-testing program should be implemented before actual installation.
During this bench testing, several problems were ider.tified which we feel make these Lastruments unsuit-able for operation at this time. Upon completion of correcting these problems and thorough testing, this new analog instrumentation will be installed.
