Cooling system
A cooling system
removes heat from the reactor core and transports it to another area of the
plant, where the thermal energy can be harnessed to produce electricity or to
do other useful work. Typically the hot coolant will be used as a heat source
for a boiler,
and the pressurized steam from that boiler will power one or more steam
turbine driven electrical generators.
Flexibility
of nuclear power plants
It is often claimed that
nuclear stations are inflexible in their output, implying that other forms of
energy would be required to meet peak demand. While that is true for the vast
majority of reactors, this is no longer true of at least some modern designs.
Nuclear plants are routinely used in load following mode on a large scale in
France. Unit A at the German Biblis Nuclear Power Plant is designed
to in- and decrease his output 15 % per minute between 40 and 100 % of it's nominal
power. Boiling water reactors normally have load-following capability, implemented
by varying the recirculation water flow.
