Valve Desig. No., Size &Type Operator Data
Rating & Purpose
- Serves to pass up to a maximum of 40,000 lb/hr
of steam to maintain saturated pressure con-
ditions in the hotwell over conditions listed
- Serves to by-pass pump flow back to hotwell,
depending on reactor make-up requirement
as controlled by valve S8.
SMA-3-60 Passes pump discharge condensate flow rates
3.89 hp listed under Sz above; maximum pressure
drop about 12 psi; to seat at maximum of
2 psi pressure differential.

These six S12 valves in combination with S15
serve function of routing feedwater through
water cooler(s) for controlled subcooling re-
quirements prior to delivery to reactor.
S12-6 to handle flow rates shown under S2
while S12_1 thru S12-s to handle about half
SMA-00-7Z Serves as sludge-handling condensate valve
0.5 hp to drain contents of hotwell to retention tanks.
SMA-1 - 15 Serves as shut-off valve between one of the
0.97 hp forced circulation pump suction lines and
the feedwater pump suction, which, when in
the open position, will permit feedwater pump
start-up circulation down the annulus sur-
rounding the reactor core.
- This valve operates, in conjunction with
the S12 valves and controls, subcooled water
flow requirements to the reactor; to handle
normally up to about half the flow rate listed
Serves as cooling water pump suction shut-off
valve; maximum flow rate 1200 gpm at 70F;
maximum pressure drop about 2 psi.
Serves to check reverse flow through pump;
maximum flow about 1200 gpm at 70*F;
maximum pressure drop 5 psi.
Serves to by-pass pump flow back to suction
side of pump if pressure builds up to pre-
determined value depending on control demands
of valves SW4.
