Why nuclear power is not the answer to climate change

TOO MANY REACTORS AND NOT ENOUGH CARBON REDUCTION

Studies performed by MIT, Commission on Energy, and International Atomic Energy Agency all agree that approximately 1500 to 2000 new atomic reactors would have to be built to reduce greenhouse gas emissions by enough to make a meaningful difference.

There are currently 449 nuclear power stations (approx), If we were running around 2000 reactors in total we would exhaust our main uranium reserves in a few decades. We would then need to mine lower grade uranium, this would itself cause more greenhouse emissions. If the potential 2000 reactors were used to replace the coal stations, we would have a 20% reduction in greenhouse emissions. If used as a new capacity to replace true renewable sources, then our emissions would actually increase.

TOO MUCH MONEY

1500 more reactors would cost trillions of dollars. New reactors going online in the US in the 1980s and 90s cost on average 4 billion dollars each. Reactors to recently come online in Japan in the last few years were in the order of $2000 / KW.

Taking an average larger power plant of 1200MW and an average conservative cost of $1250 / KW, this gives a construction cost of 1.5 billion.

Yearly costs per 1000kg of avoided CO2 emmisions are $68.9 for wind and $132.5 for nuclear power.

TOO MUCH TIME

Construction of 1500 new reactors means that we will need to open a new reactor every 2 weeks beginning today, for the next 60 years. This is impossible as the current nuclear manufacturers are only capable of doing half this amount if they are pushed to their absolute capacity. Climate change cannot wait for Nukes.

TOO MUCH WASTE

Operating another 1500 or more new reactors would create the need for a new Yucca Mountain sized radioactive dump site somewhere in the world every 3 to 4 years. Yucca Mountain has been in progress for almost 20 years and still is at least 10 years from being finished. The state of Nevada has also vigorously opposed the construction of the Yucca facility.

Due to the opposition to radioactive dump sites many countries including the US are attempting to reprocess the nuclear waste, as a means of managing the waste. This is a dangerous technology, linked with increased Leukemia rates amongst children living nearby reprocessing plants as a result of increased radiation being released into the surrounding environment.

Wong is Wrong

Well I just couldn’t resist and whilst in the moment I’ll add, two Wrongs wont make a right either Ms Wong.

This post is regarding Australia’s minister for Climate Change and Water (Penny Wong) and her relative inaction regarding Professor Ross Garnaut’s interim greenhouse review.

The story so far. Australia is dominated by the Banks, the Resource industry and the Industrial Farming sector… they are the ones, who at present with more than a little help of the Rice & Cotton mob in the not so deep north, who justify their greed with the defense of ‘export growth’ & ‘jobs’, whilst the mob in the not so deep north go on butchering our most important Murray Darling waterway.

The Garnaut Climate Change Report is handed in and it tells us what most thinking people already know… like it’s not that hard to realize that to freeze the World’s pollution at sort of 1990’s levels, when there were already signs of climatic arrhythmia, is not unlike closing the barn door after the horse has bolted… to the power of a number just sightly south of infinity.

Can chocolate be eco friendly

EcoChocolate

ABC news Australia reports; “Chocolate-eating bugs provide fuel of the future”

” Chocoholic germs can provide hydrogen, the clean-burning energy of the future, New Scientist reports. ”

” British scientists fed Escherichia coli bacteria a diluted mix of waste caramel and nougat. The germs tucked into the sugar and in the process produced hydrogen, using their own enzyme, called hydrogenase. The hydrogen was used to power a fuel cell, generating enough electricity to drive a small fan. ”
