Valve in Minimum Flow Recirculation 1.ine".
The licensee responded.to this.
L bulletin in a ' letter dated November 11,L1986: and stated that they had'
!
evaluated the bulletin to determine whether'a single-failure vulnerability
'
exists in the minimum. flow recirculation linet of any ECCS pump that;could.-'
cause' a failure of -more than.one ECCS. train. : Their evaluation' has concludedithat the concerns of-the bulletin are not applicable to this
. The only ECCS components. that share. commonEminimum' flow i
facility.
recirculation lines and/or valves are the Safety Injection. System (SIS)'

and the Chemical Volume and Control System (CVCS).
The SIS has miniflow-return lines to the Refueling Water 3torage Tank (RWST). The lines become common after the pressure breakdown orifices for each pump.
The-incividual portions of the miniflow lines contain an isolation valve each, and the common portion contains a single valve.
All of these valves are motor operated and as such are fail-as-is upon loss of control circuitry or power.
The CVCS minimum recirculation normal flow paths connect to a common line that contains a single motor operated isolation valve that is also fail-as-is upon loss of power.
On a safety injection signal, the CVCS pump miniflow paths automatically align to alternate miniflow paths which have no common valves.
Based on an in-office review by the Region II inspectors this. item is closed. Closure for unit 1 is via report 50-424/87-56.
