Should Greens consider Thorium reactors?

Debate topic for pragmatic GREENs

Thanks to a tweet by Enviralment I just read an article on Thorium reactor technology that I think people should read. Thorium reactors have been around for quite some time but because of their inability to be weaponized they never received the same funding or hype that conventional (uranium) reactor technology received. I've looked at thorium technology a number of times not only as because I love tech stuff but also as GREEN compromise position to the outright moratorium on nuclear plants.

Thorium has a number of major advantages or Uranium reactors

1. Fuel is 10 times more abundant and readily available in the waste streams of existing metal mines. This will ensure a good supply without additional mining of any kind especially Uranium mining. Thorium technology will also keep fuel prices low compared to what will happen if a major build out of new Uranium reactors is begun. Ur prices have been suppressed for decades because of the availability of reprocessed Russian warheads taken out of service in arms control deals, this supply stream is ending and Ur prices will skyrocket in the next decade if major new projects come on line.

2. Thorium reactors are self regulating and don't need expensive and dangerous high pressure systems, lower costs and lower risk.

3. Thorium waste is only hot for a couple hundred years and contains fewer exotic and toxic materials. While still a major storage problem this fact greatly improves the long term logistics of nuclear waste.

4. Thorium reactors can be built without worries of weapon development, You can't make a bomb from it so places like Iran can build them without threatening their neighbours.

5. Thorium reactors can be used to downgrade the toxicity of other nuclear wastes containing plutonium while using them as part of the fuel mix. This reduces dangerous waste and weapons grade fuel, win/win.

So, if an increase in nuclear reactors is inevitable as many people including some environmentalists now believe would it not make sense to throw our support behind a more earth friendly nuclear alternative (thorium) rather than stubbornly demand no nukes at all?

In a energy deficient future were we may lose the all or nothing argument against Uranium reactors, is thorium both viable and comparably safe enough that greens should consider this technology a compromise position to a nuclear moratorium?


I'm realistic/pessimistic enough to believe we may well lose the nuclear argument in a energy starved future, I'm also pragmatic enough to think we should at least debate a lesser of evils compromise where both sides can claim a victory?

I'm torn but would still like to see it debated by real environmental and nuclear experts

What do you think?

Just a thought on resource depletion, emergency preparations and economic resilience!

Most people who've heard of peak oil accept that it is a real phenomenon. Many people also realize that with rising world populations, increased consumption and the growing affluence of Asia that there will be a great many commodities from food, silver, distillates, catalysts, chemicals, rare earths and energy that will come into short term or permanent shortage at some time in our near future.

It is my belief that the GPC needs new ideas that will not only work towards the reality of resource depletion by advocating reduced consumption but at the same time creating policy that will strengthen Canada's resilience to the economic shocks caused by possible shortages. With this in mind I think that the GPC should adopt policy calling for the creation of regional strategic stockpiles that work with industry to make sure that primary materials required for the smooth operation of Canadian economic engine do not run out due to short term market shortages, or environmental emergencies.

I would also suggest that strategic reserves of grains, emergency supplies, and vital infrastructure components should be created so that in case of something like a massive blackout, ice storm, solar flare, hurricane etc. important infrastructure like the power grid or water treatment system can be restored in a timely manner without relying on foreign deliveries or waiting for the manufacture of damaged equipment. I'm sure there are already some government and utility provisions in place for such events but with the combination of resource depletion and the expectation of more volatile weather from climate change these programs surely need to be beefed up.

Now I admit there is no way to hoard our way to prosperity but having a strategic reserve for for energy is something most counties have. We do not! Canada always makes excuses for itself because it’s so big and cold, all the more reason to have a stockpile so no one ends up freezing in the dark, NO?

In today's just in time delivery system a strategic supply of food is only sane considering grocery stores and the distribution system only have a few days of anything in stock.

A strategic supply of rare earths for example will not keep us in business if the world runs out but would certainly keep industry running during a short term delivery interruption and would also be a great carrot to entice manufacturing companies to set up shop in Canada. Rare earths are especially important to those Green Techs we claim we wish to support like the manufacture of PV units and wind turbines.

Precursor chemicals for common and wide spread drugs like thyroxin, blood thiners or increased stockpiles of insulin might also be wise.

This is not an over night project but something that would take the better part of decade to build up to. Consultation with industry, economists, logistics people and the prioritization of which materials to stockpile would be a project unto itself but certainly energy and food should top of the list.

We are also in a time when currencies are going wild, the possibility sovereign defaults are being openly considered and it might just make sense to put part of our reserves into something that is real, growing in rarity and vital for our economic engine rather than more U.S. T bills.Recommend this Post
