c' LER ATTACIOfENT - RO # 2-80-70 facility: BSEP Unic No. 2 Event Date: 09-10-80 The valve actuator coil wire is believed to have been broken during the installation of qualified splices as addressed in LER 2-80-47.

A plant modification has been written to replace the valve top works on all ADS valves which will incorporate terminal blocks in place of splices to I

allow a more reliable termination of external actuator wiring. This modification will be installed on each unit during the next outage of sufficient length.
