Nuclear Energy Why it IsNeeded?

It is coming to a time wherehumans need more sources ofelectricity as they havebecome dependent on it andfossil fuels wont be around for

ever. So we need analternative source. You canuse renewable energy butthey are not very reliable asthey cant be used consistentlyas they need certain elements

to run them e.g. wind powerneeds wind which cant bearound all the time. This iswhere nuclear power fits in asone piece of uranium canpower up to 80 houses, their

can be benefits of usingnuclear power but their can

How A Nuclear Power Plantworks

First the uranium is processed to a fuel pellet. The generatoris spun by using a steam turbine, the nuclear reactor can boilthe water to turn it into steam. The nuclear reactions heatdifferent water or gas or even liquid metal first. Then thecoolants carry the heat energy in to the boiler the water

passes through the turbine by using water pipes. The coolanttransfers its heat energy through the boiler pipes to theturbine water, which is boiled into steam. The coolant wouldcontain a radioactive substance as it has passed through thereactor. The coolant is heated by the metal fuel rods thenuclear reactions cause to get hot. Then it would go through

to the generator which contains electromagnets which areused for making electricity and to control it when theelectricity it is turned on or off in peoples homes which is thenpassed through a transformer of electrical current . The fuelrods are just hollow metal cylinders The fuel pellets are verysmall so the fuel rods are very thin. The fuel rods are bundled

into fuel assemblies. The fuel assemblies are engineered tomake it easy to fuel and unload the reactor. The fuel pellets

Nuclear Fission

When a nucleus fissions, it splits into severalsmaller fragments. These fragments, or fissionproducts, are about equal to half the original mass.

Two or three neutrons are also emitted.

Benefits And Disadvantages

Benefits of using nuclear power is:

- A sustainable source of electricity

- It wont harm the planet by global warming as it releases nofuel emissions

-- Disadvantages are:

- Expensive to produce uranium- If there is a nuclear explosion it could be catastrophic as itwould destroy everything in its range and the place will

become radioactive and it would be unsafe to visit the placefor 100s of years

- It could cause more developments in nuclear weapons asmore countries would be using nuclear power

- People who work at the power plants are more likely to get

radiation poising
