What are advantages and disadvantages for nuclei reactor as an source of energy?

Answer 1

Advantages of Nuclear Power

· Efficient: Nuclear plants can produce an awful lot of electricity, up to about 2GW, which is comparable to coal plants.

· Reliable: There is no need to worry about interruptions to the power supply: as long as there is uranium, there will be power. This is a stark contrast to most renewable energies which depend on the activity of the weather.

· Clean: I'm using this term strictly to refer to the greenhouse gas emissions of a nuclear plant. There is some greenhouse gas emissions associated with the life cycle of uranium, as gases are emitted as it is mined and transported etc. However this is significantly less than the emissions associated with the burning of fossil fuels. Essentially, nuclear power would be "carbon-zero" if the uranium were mined and transported in a more efficient way. There are issues with radioactive waste, however.

· Supply: No, it's not going to last forever, but at least what there is more easily accessible than oil. 24% of uranium resources are in Australia and 9% in Canada. These are hardly politically unstable regions!

• Nuclear power plants don't take up much space. This allows them to be placed in already developed areas and the power does not have to be transferred over long distances.
• Another advantage of nuclear power is that nuclear energy is by far the most concentrated form of energy, so it can be produced in large quantities over short periods of time.
• The possibility for long term production is great since new reactors, where costly can be made when the old ones wear out. Oil reserves and other fossil type fuels are likely to run out at some point.

Disadvantages of Nuclear Power

· Waste: High level radioactive waste is very dangerous. It lasts for tens of thousands of years before decaying to safe levels. If there is to be a "nuclear renaissance", a sophisticated method of storing the waste for this period of time must be designed. This point itself has sparked a surprising number of debates.

· Proliferation: Some forms of nuclear reactor, known as "breeder" reactors produce plutonium, which can be used to make nuclear weapons. There are other reactors which do not have this problem, but it is another issue which must be addressed before the possibility of a nuclear future can be taken seriously.

· Terrorism: While the chances of a modern reactor exploding like Chernobyl are near zero, it is quite possible for intervention to have quite horrific results. Nuclear plants would be very tempting targets to anyone wanting to disrupt the power supply and devastate an entire region in one foul swoop.

· Cost: Nuclear plants are very expensive to run. I'm not an economist, but I believe nuclear plants are, like most other things, cheaper in bulk. Most of the cost comes from the initial building of the plant; the running costs are comparatively low.

• Nuclear Power generates radiation, which can be harmful or even fatal to infected people.
• A nuclear meltdown can often occur which will release massive amounts of radiation into the community.
• Extremely radioactive nuclear waste is produced by nuclear power plants. This stuff can't be just thrown out. The US plans to move all its nuclear was to an underground dump by the year 2010. Currently it is stored in the plants.
• Nuclear waste dumps can spontaneously combust without warning.
• Nuclear reactors only last for about forty to fifty years, so where they are extremely productive, they break down and are costly to replace.
• There are international dangers too. Some reactors produce plutonium which can be used to make nuclear weapons. If the whole world were to use these, they would have unlimited access to nuclear weapons

it can produce alot of energy every year, more than a normal station can produce

Answer 2

There is a long list of advantages of using nuclear energy like power health agriculture , crime detection , power sources, isotopes and others but it has highest disadvantage of mass destruction and radioactivity

Answer 3

here are a few of them:

1) they donot cause pollution.

2) they donot contribute to global warming.

3) they are renewable (i.e they donot get over).
