' REQUEST--FOR ADDITIONAL INFORMATION tr SNUPPS FSAR-

• f 20 450iOJ 3 ACCIDENT EVALUATION.

Q 450.10. lThe -SNUPPS' FSAR indicates that the mode of initiation of'switchover

~

-(6.5:2)-

(RSP)E ofithe_containmentspraysystem. suction'fromth'eRefuelingWater

~ I Storage' Tank tol the containment' sump is l manual..The sta'ff_ finds that this practice departs from that currently deemed acceptable'. SRP

'Section 6.5.2 (II.. Acceptance Criteria, item 2.a) states.L"The conta'in-

~

ment spray system should be designed...~ and should be capable of-continuous operation.thereafter until the design objectives of the system have been achieved.

In all cases tne operating ceriod should not be less than two; hours." Manual initiation of the switchover does not' guarantee continuous operation for two hours and does not crovide assurance that the d' esign objectives of.the spray system are achieved for delayed fission croduct releases frcm the core.

It is the.

staff's position that we require a design modification which wili t

' change from manual to automatic the switchover of the containment-spray system from the RWST to the containment sumo.

State your. intent regarding compliance with our position.
