Nuclear energy disadvantages essay
A fission reactor contains nuclear energy disadvantages number of different parts: Many of the read more of nuclear energy disadvantages essay reactor are designed to control the speed of the reaction and the temperature inside the shielding.
Band 8 essay sample | Advantages of nuclear energy outweigh disadvantages
An uncontrolled fission reaction is the basis of an atomic bomb. Generating electricity using nuclear reactors carries high risk but offers large essay. In operation, a very small amount of nuclear nuclear energy will consistently generate a very large amount of electricity and generate very little polluting material. However, the financial costs of building and disadvantages essay a nuclear power station are very large, and the waste produced will remain radioactive - hazardous to humans and disadvantages essay environment - for thousands of disadvantages essay. Fission reactors A fission reactor contains a number of different parts: Nuclear fuel - the essay or plutonium isotope that will split when triggered by an incoming neutron.
The fuel is held in rods so that the neutrons released will fly out and cause nuclear fission in other rods. Moderator - graphite core - a graphite core, for example, slows the neutrons down so that they are more nuclear energy disadvantages to be absorbed into a nearby fuel rod.
Control rods - these are raised and lowered to stop neutrons from travelling between fuel rods and therefore here the speed of the chain reaction. Coolant - this is heated up by the energy released from nuclear energy fission reactions and is used to boil water to drive turbines in the power station.
Essay shield - disadvantages essay daughter products of the fission reaction are radioactive and can be a hazard. Advantages and disadvantages essay nuclear power stations Generating electricity using nuclear reactors carries high risk but nuclear energy disadvantages essay large rewards.
Advantages Disadvantages Produces no polluting gases. Waste is radioactive and safe disposal is very difficult and expensive. Does not nuclear energy disadvantages essay to essay warming. Local thermal pollution from wastewater affects essay life.
