nuclear energy facilities generate carbon free electricity in thirty
countries around the world nuclear energy production is similar to the ways
fossil fuel to power plants generate electricity
a nuclear energy facility provides clean safe electricity twenty four hours a day
let's go inside the plant to find out how in most generating plants weather
cold nuclear or natural gas
some form of energy is used to heat water into steam
this team transit turbine produced coupled to an electromagnetic called the
generator
the generator produces electricity
while the model is the same there is a key difference between nuclear energy
facilities and other electricity generating plants power plants that ran
on fossil fuels burn coal oil or natural gas to generate the heat that creates
steam
in a nuclear energy facility
chain reaction of splitting adams releases heat
this reaction takes place in the reactor
hall reactors are designed built and operated with safety as a top priority
nuclear energy facilities are among the safest facilities in the world
because they feature
multiple redundant layers of safety systems and procedures
beginning in the core of the reactor
in a nuclear reactor metal rods with enriched uranium pellets inside are
placed into bundles creating a few will assembly
the bundles are submerged in water inside a pressurized vessels
the two most common types of nuclear reactors are boiling water reactors and
pressurized water reactors
in a boiling water reactors
the heat from split adams causes the water to boil producing scheme that
drives a turbine
afterwards this team is converted back to liquid water
and returned to the reactor core
pressurized water reactors torpedo value walkers were developed after boiling
water reactors and work in a slightly different manner
in a p w_r_ the water in the reactor tank is under pressure to keep it from
boiling even though it reaches very high temperatures
in the steam generator of api w_r_ water passes through thousands of small pipes
the heat in the pipes turns the water to steam
which then drives the turbine
but turbine power is the generator which in turn produces electricity
here is where the process differs from a boiling water reactors the reactor water
is now pumped back into the reactor tank and he did again
this came from the turbine is cool dinner condenser
and the resulting watery sent back into the steam generator and he did again
to prevent overheating
control rods made of a material that absorbs small atomic particles
are inserted into the nuclear fuel bundle
when an operator wants to produce more heat the control rods are raised out of
the bundle
to create less heat they are lowered into the bundle
the rods can also be lowered completely
to shut the reactor down
in the case of an accident for two weeks you'll the facility
with this level of control
the operator of a nuclear energy facility is able to ensure that it
continues to generate clean safe and secure energy
additional safety systems are in place
that shocked the reactor down quickly and stop the fission process
rule the reactor down and carry heat away from and create barriers to contain
any radio activity
and prevented from escaping into the environment
nuclear energy facilities are the most efficient source of electricity in the
world
by developing a nuclear energy program
the ueda sleeping the way for other nations that may look to generate clean
safe electricity in the future
nuclear energy for the u_n_
part of a bright future
for our people
