Norway is building thorium reactor

If I am correctly informed (would love to hear from people who are involved in the project), this project is being done in spite of the Norwegian government's stance on nuclear energy.<p>Thor Energy and its associated researchers have tried to stir up support for thorium reserach for years now, but there has been very little support and large amount of uninformed opposition ("nu-cu-lar is baaaaaad"). A number of physicists, notably Egil Lillestøl at the University of Bergen, have talked to official figures about this for a long time about this without getting any kind of traction.<p>Thorium energy seems to be a very promising candidate for safe, clean and cheap next-generation nuclear power. If these researchers manage to develop something without official support, it would be impressive indeed. That the Norwegian government isn't willing to support clean energy research is really quite baffling, given that the energy sector is hands-down the largest contributor to the Norwegian economy. And Norway has the world's second-largest known thorium reserves. For all our supposed good policies, we are still subject to mob rule and completely uninformed detractors.

This isn't one of the fancy liquid fluoride thorium reactors that people immediately think of. It's a scheme for incorporating thorium into the fuel mix in existing reactors. Still very cool.

For those who haven't seen it, I highly recommend this video on liquid-fluoride thorium reactors (LFTR): <a href="https://www.youtube.com/watch?feature=player_embedded&#38;v=P9M__yYbsZ4#" rel="nofollow">https://www.youtube.com/watch?feature=player_embedded&#38;v=...</a>!<p>I passed the video by my uncle who was an expert/engineer dealing with control and safety of water cooled reactors. This is what he had to say:<p>"I found the video very informative technically, as well as being effective in countering many of the the arguments of those who profess to be against nuclear power in any form. I also found the details of the design of the liquid thorium fluoride reactor intriguing. To become an advocate for further investment in this concept, I would have to learn more about how the concept deals with the safety issues involved in the handling of fluorine gas and fluoride materials."

It seems this has sparked some debates on nuclear vs renewable energy so I thought I'd add a ted talk that explains some pros/cons of each for those interested: <a href="http://www.ted.com/talks/david_mackay_a_reality_check_on_renewables.html" rel="nofollow">http://www.ted.com/talks/david_mackay_a_reality_check_on_ren...</a>

The title is misleading. They only test thorium in an already built conventional reactor. Meanwhile in Germany they developed a conceptionally more safe reactor type powered by thorium, built a test reactor (<a href="http://en.wikipedia.org/wiki/AVR_reactor" rel="nofollow">http://en.wikipedia.org/wiki/AVR_reactor</a>) and an industrial reactor (<a href="http://en.wikipedia.org/wiki/THTR-300" rel="nofollow">http://en.wikipedia.org/wiki/THTR-300</a>). They're both shut down now, partly because of safety concerns: Water leaking into the cooling circuit can lead to explosions (which happened in small amounts)<p>So I guess only time will tell if new reactor types really are better than current ones.

Interestingly this has already been done in the U.S. kinda. Back when I was working on Indian Point Units 2 &#38; 3 I found a paper about Unit 1 where - about 30 years ago - they mixed in some of the fuel bundles with Thorium to see how well the neutron flux would turn it into Uranium and possibly breed more fuel. It was really fascinating but, although they had some success, there was really no need for it in the U.S. because Uranium is not in short supply and as this article points out, solid fuel reactors kind of dismiss all the advantages of thorium.

While germany is getting out of nuclear power altogether... their "Energiewende" plan is very ambitious but i wonder if its not better to invest into nuclear power to make it saver instead of getting rid of it completely. I dont know much about it though, what do experts think?

Kalpakkam, India has already been in works for years! The design for it according to wikipedia had been started in the 80's.<p><a href="http://en.wikipedia.org/wiki/Prototype_Fast_Breeder_Reactor" rel="nofollow">http://en.wikipedia.org/wiki/Prototype_Fast_Breeder_Reactor</a>

A Liquid Fluoride Thorium Ractor is as safe a unit as is possible. Look it up online. Much safer, cheaper, and more versatile than a bulky CANDU. It can be throttled and scaled which is a huge advantage. There is plenty of easily accessable thorium worldwide. It also can generate radioisotopes that are extremely useful and much more readily extracted from the reactor than those currently used. Time to begin building these.

Peter Thiel's class had an interesting part on Thorium: <a href="http://blakemasters.tumblr.com/post/23787022006/peter-thiels-cs183-startup-class-14-notes-essay" rel="nofollow">http://blakemasters.tumblr.com/post/23787022006/peter-thiels...</a>

According to an article in a norwegian newspaper[1], there are much bigger challenges in extracting the thorium from the ore in Norway. The thorium in India is supposedly easier utilize.<p>The technology today requires use of a lot of nasty chemicals to extract thorium. I think this is a big issue for the government in addition to running nuclear reactors.<p>[1]In norwegian: <a href="http://www.aftenposten.no/okonomi/Gigantisk-energikilde-i-Telemark-7055485.html" rel="nofollow">http://www.aftenposten.no/okonomi/Gigantisk-energikilde-i-Te...</a>

There's no insinuation in my posting this link, and it's not directly pertinent to Thorium reactors, but the free PDF downloadable from here is a good reference for these kinds of discussions, I think. Helped me with perspective anyway.<p><a href="http://www.withouthotair.com/download.html" rel="nofollow">http://www.withouthotair.com/download.html</a>
