What is nuclear energy?
The nuclear cycle is a complicated process. So let’s keep it simple.
Most energy is created by some sort of steam power. When water boils, the steam pushes turbines that make your car start, your lights flick on and your stove light. Currently, most (78 per cent) of Australia’s water is boiled by coal. Coal, as a fossil fuel, creates greenhouse emissions.
So…nuclear energy is a way to boil water without producing greenhouse emissions.
How is nuclear energy made?
Nuclear energy is derived from uranium. Currently, 30 per cent of the world’s uranium reserves are in Australia, followed at a distant second by Kazakhstan on 17 per cent. There are eight uranium mines in place throughout Australia.
Once uranium is mined, it undergoes a refining process, where the uranium is ground, sifted and enriched. Once all of the energy from the uranium is used, it becomes nuclear waste and is stored in various ways (check out the nuclear waste fact sheet by kellyendo for more on this process).
So are we on nuclear energy?
No. Most of the energy in Australia is supplied by burning coal or petrol. All of the uranium mined in Australia is exported. But if you’re worried about Australia supplying the tools to make nuclear weapons, don’t be. Each country that buys uranium from Australia must sign an agreement that the uranium will be used only for peaceful purposes (like generating energy).
Why aren’t we using our own uranium?
Australia is in the midst of a debate about our nuclear policy. In June 2008 Prime Minister Kevin Rudd ruled out nuclear energy as a possible alternative energy source to help lower carbon dioxide emissions. Conversely, in July 2008 Liberal Party leader Julie Bishop called for the nuclear energy debate to be reopened, believing nuclear energy to be a possible solution to global climate change.
Disagreements over the blanket bans on uranium mining in Western Australia and Queensland also continue.
New carbon emission targets require the federal government to spend six billion dollars on new technology that uses alternative power sources by 2020. Dr John Burgess, author of the 2009 Australian Academy of Technological Sciences and Engineering’s report on alternative energy in Australia, believes that the key to cutting the carbon emissions in time is nuclear energy. However, federal Energy Minister Martin Ferguson maintained that the Labor government will not support the recommendation for exploring the nuclear energy option.
Those who are opposed commonly say that nuclear power would not cut greenhouse gas emissions significantly. Scientists says that only five per cent of emissions would be cut by 2050, which is well below the target number that has been set to reduce climate change. The opposition also cites nuclear disasters, such as the Chernobyl power plant meltdown in the late 1980s, and argues that such a disaster could happen again. Others worry that if Australia goes nuclear, our uranium supply could run out in less than 60 years.
