The nuclear power plants
are
specials thermoelectric power
plant.
Althught they
are
thermoelectric power plants, they don't
produce
heat
by burning fossil fuels, such
as
coal,or
oil,so
they
produce
energy by fission
of
Uranium
or
Plutonium
atoms
.

How
does
nuclear power
station function
?
The reactor is where fission take place.The uranium is
placed in very
thin
rods about 4 m long know as fossil
rods
Control rods
regulate
the power produced by
the
reactor
and
can be raised and
lower.
Water
is
pumped around
the
reactor. This water
is
used
to
refrigerate the
reactor.
The primary circuit: water enters a steam generator. Then it
flows
back
to
reactor.
The water in
the
secondary circuit
is
transformed
into
steam,
that
moves
turbines
and
collect
the
energy that
it
produce
in
the
collector connectated
to
the
turbine.
Fossil fuel thermal power
plants
A
fossil-fuel power
station is a type of
power
station
that burns
fossil
fuels
such
as coal
to
produce
electricity.
Fossil
fuel
power
stations
have
machinery that transforms
the
heat energy
of
combustion into mechanical energy, which then operates
an
electrical
generator
.
How
does
thermal
power
stations
function?
Steps to transform certains materials such
as
coal, in
thermal power
stations:
1
st
step: Coal is burned in to the boiler to produce heat.
2
nd
step:
Thermodinamyc process consist
of:
-The
heat produce
by
burning fossil fuel materials boils
water
and
transform it into
steam.
-The
steam is then
piped
to
a
turbine.
-The impulses
of turbine
moves
the
turbine.
-Finally,
steam is condensed
and
move
into the boiler
to
repeat the
cycle.
3
rd
step:
Rotation
of
the turbine
rotates
the
generator
to
produce
electricity.
Hydroelectric power plants
The hydroelectric power plants are stations where
energy is produced by
the
force of falling
water.
The water moves
a
turbine connected to
a
generator
that
collect the
energy that water
creates
.
Non-conventional electic power
plants
-Wind power plants and
wind
farms
Wind
stations are the
ones
that transform
wind energy
into
another usefull kind
of energy.
A wind
farm consist of almost
a
hundred of winds turbines
connected
to
electric
power
transmission
network.
Parts of
turbines;
Rotor blades: Captures wind
energy.
Shaft: Channelizes
the
energy
to
a
generator.
Generator:
Collect
energy.
Solar power
plants.
That kind of
power
plants creates
energy by
transforming the
heat
and
light
from the
sun.
There
are two
types;
-Solar thermal
energy:
It
stores
the heat of the
sun, which transform water into steam, that
moves
turbines which
are
connected
to a
generator
that collect
energy.
-
Photovoltaic energy:
Is
a
method
of
generating
electrical power
by
converting solar radiation into
direct current
electricity.
Geothermal power
plants
The
geothermal power
plants are
plants where energy
is
created by the
earth's
interior
heat.
Geothermal power
is cost effective, reliable, sustainable, and
environmentally friendly,
but has historically
been limited to
areas
near tectonic plate
boundaries.
Geothermal
electric plants
were traditionally
built exclusively
on the
edges
of tectonic plates where
high
temperature geothermal
resources
are
available
near the
surface.
Biomass
thermal power
plant
The
biomass thermal energy
consist in
burning the natural
waste
and
rubish, such
as plants,
animals,
food...
It
produces natural gases
that provides
heat
to
water,
and wich
transforms
it into
steam, that later will move
a turbine
connected toa generator that collects
energy.
Ocean power
plants
The ocean power plants produce
energy
by
ocean waves
movements.
That
movements
move
a
turbine connected with
a
generator
that
stores
that energy.
The waves are produce
by
the wind in contact
with
surface.
If the waves
move
slow, the
energy
will
be
lower
than if the waves
are
faster.
Enviromental
impacts
Conventional
enery
impacts:
-
Fossil-fuels thermal
power plants: Athmosferic
pollution
from
gas
combustion
-
Nuclear
power plants:
Danger of radiation
and
contamination.
-
Hydroelectric power plants: Produces changes
in
the
enviroment.
Non-Conventional enery
impacts:
-Wind
power:
Visual
and sound
impact.
-Solar
power:Affecfs ecosystems as it covers large
areas.
-Ocean power: Envirometal changes resulting from
required
construction
work.
Explore the functioning of various electric power plants including nuclear, fossil fuel thermal, hydroelectric, wind, solar, geothermal, biomass, and ocean power plants. Understand the processes involved in generating electricity from different energy sources such as fission, combustion, steam generation, turbine rotation, and electricity generation.
