THE NUCLEAR STEAM SUPPLY SYSTEM OF THE 900 MEGAWATT WATER NUCLEAR POWER STATION
The nuclear
PRESSURIZED
supply steam
system
for the
900
megawatt
pressurized
water
nuclear power
station consists of a
reactor
surrounded
by three
loops.
Each
loop consists
of
a
steam
generator
and
a
main
pump.
The three
loops
use
the
same
pressurizer. They are installed in the containment vessel.
