Pros And Cons Of Nuclear Energy Use In Australia

Nuclear Energy…Is it an option for Australia?

Yes, nuclear energy is an alternative to fossil fuels, but is it safe? No, I think not. Nuclear energy is a danger to the environment and everything in it and this report will detail the pros and cons of this risky alternative and look at other possibilities to care for our everyday energy needs.
It might help you to understand my views if you know how nuclear power works. There is a vast amount of energy found in the nucleus of the atom. This is where nuclear power comes from.
The fuel used by nuclear plants for nuclear fission is uranium. Uranium is non-renewable. Uranium, U-235, is used because its atoms can be split easily. Once uranium is mined the U-235 must be extracted and processed before it can be used.During nuclear fission, a particle called a neutron hits the uranium atom and splits it, releasing an immense amount of energy as heat and radiation. More neutrons are released and these neutrons go on to bombard other uranium atoms, and the process repeats itself. This is called a chain reaction.
Fission generates heat in a reactor, and then the heat boils water into steam. The steam turns huge turbine blades and as they turn, they drive generators that make electricity. Afterward, the steam is converted back into water and cooled in a cooling tower. The water can be used again and again. (This water use is also a concern).
After all this has occurred and the uranium can no longer be used, what do we do with it? Dump it in a nearby river? Or perhaps bury it underground, where no-one knows it’s there? “The issue of safe disposal of radioactive waste & outdated plants has not been resolved”, [1] says environmentalist David Suzuki. Jeremy Rifkin agrees. “Sixty years into the nuclear era, our scientists still don’t know how to safely transport, dispose of or store nuclear waste”. [2] “Nuclear waste can have half lives of 10 000’s of years. No civilization has lasted that long.”[³] It doesn’t really matter where you dump the stuff, it’s going to affect the environment in a negative way.

Waste disposal isn’t the only problem that I see with nuclear energy. There are several other points that need to be explored, the first: terrorism. People could easily go into a nuclear facility and do one of two things. Steal the radioactive material for bombs or blow the place up. This is why they are a major target for terrorist groups. The production of nuclear electricity in countries that have not signed the Non-Proliferation Treaty is a worry for any country that is afraid of nuclear war. Any nuclear plant can be quickly converted into a nuclear bomb-making facility. “Isn’t it hypocritical of us to go to war with a country over non-existent nuclear weapons, yet we supply most of the world’s uranium, and now suggesting that we use something that could give us the upper hand on the little guy if World War 3 broke out?” (Maria Hele-Kapodistria.) Don’t we think it’s about time we start thinking...

Pros and Cons of Renewable Energy

2101 words - 9 pages Germany and Italy decided to either close all existing nuclear reactors or significantly reduce the number of nuclear power plants originally planned. Reducing or ending reliance on nuclear power ultimately led them to diversify their energy mix, and one strategy is to increase the use of renewable energy. In this favorable trend toward renewable energy, however, there are still disputes over whether governments should engage in promoting and

The renewable energy is natural and continuous in the environment. Wind has been used for energy for thousands of years. Throughout time many historical applications have used the wind to generate a specific task. For example, sails of a ship use the wind to propel

Today as the price of oil is at its peak and graph of oil has increased very much and green houses and pollution is also much increasing day by day (Borah, 2011). This is actually a time to fight with these sorts of problems because in this way our Earth will become sicker as it is now so we must start contributing and with the unity we have to work hard for the regeneration of energy. These sorts of energies include many of

Nuclear Energy – To use or not to use Uranium for energy production in Australia

804 words - 4 pages Many countries around the world generate electricity by harnessing energy from nuclear fission of ‘fuel’ such as uranium rather than burning fossil fuel. As an example, the electricity produced by burning 17,000 kg of fossil fuel can also be produced from 1kg of uranium, but should Australia use it? Australia has always used fossil fuel to power thousands of homes and businesses. There are four main fossil fuels; Coal, Natural gas, Oil and

Although, in some instances, migration has positive effects; this is not always the case. Firstly, research done by Arah, Ogbu & Okeke (2008) suggests that, physician emigration leads to: brain drain and lack of effective, high quality health systems. Secondly, environment migration, as stated by Graeme (1996) increases
