How Do You Make A Bandana Mask

knowledge of nuclear energy and nuclear Nobel Peace



nuclear energy is the energy we have some substances such as uranium or plutonium. These substances are said to be radioactive. A small amount of these substances produce a lot of energy.

The advantages are that nuclear energy is very efficient, ie the fuel generates a lot of energy and emits no greenhouse gases.
the disadvantages are that nuclear energy produces radioactive waste and that an accident could cause damage over large areas.

The

Nuclear plants are plants that use the heat generated by nuclear energy to produce steam that spins the turbine. The operation of a nuclear plant is follows:

in the reactor is to merge the atoms of plutonium, uranium or radio, releasing lots of heat energy that allows evaporation of water present in the many pipes that found around the boiler. Water vapor becomes much pressure, which is used to drive a turbine connected to the generator. By rotating the turbine produces electricity, which travels from the generator to the transformer, which raise the tension to transport this energy by the power supply until the consumption centers.


On the other hand is operating the cooling system that allows you to start the cycle again, ie, condensed water vapor that can be reused. Water is condensed in a central part of the low temperature is maintained through a closed piping system that cooled the condenser. Pipes containing cold water reduces the temperature of the water used to move the turbine, allowing it to condense. When the cooling water is heated, it goes to the cooling towers, where it is further cooled in contact with cold air. And that is continuously performed the same cycle.

The parts of a nuclear power plant are:

Reactor, is responsible for causing the evaporation of water. Turbine
: in charge of moving the generator to produce electricity.
Generator: It is responsible for producing electricity. Capacitor
:
is responsible for condensing the vapor that is responsible for moving the turbine.
Cooling towers : They are responsible for maintaining low condenser temperature, ensuring the proper functioning of the plant.

The advantages that nuclear plants are as follows:

These plants produce electricity much
.
not directly pollute the atmosphere.
not depend on fossil fuels.

The disadvantages that have nuclear power plants are:

These plants produce toxic and radioactive waste can cause disease.

damages the environment because radioactive particles waste.

radioactive waste storage is a big problem.
