Whether or not that was true in the past, it's not reasonable to assume that these concerns continue to be valid.


Good for China - thorium and molten salt reactors.


Whatever happens, we mustn't allow outdated concerns and prejudice hold back the work we need to do to find solutions.

Thorium-based molten salt reactor system


One needs a good grasp of nuclear physics to separate the potential benefits from the nuclear industry?s self-serving hype and misinformation.


The underlying principle was developed at the US Oak Ridge National Laboratory in the 1960s. In the fifty years since, as far as is known from information in the public domain, no practical commercial design, let alone a working reactor, has been developed.


Despite vociferous claims to the contrary, if those reactors had been built at Fukushima Daiichi, there is a high probability that their entire nuclear cores would have become dispersed throughout the Pacific Ocean following the T?hoku earthquake of 11th March.

The lack of development in the 1960s is widely attributed to the attractive secondary benefits of uranium based nuclear processes in the creation of weapons.


As a dedicated consipracist I don't know why you wouldn't support that interpretation HAL9000?


More rationally, an oil rich 1960s USA obsessed with communism and unfamiliar with the 21st century issues of peak oil and environmentalism had no real incentive to develop 'clean nuclear' and government funding was limited.


On the 'vociferous claims' you refer to I'd need to see sources and qualification on both sides. You do have a track record of using the ramblings of socially disadvantaged paranoiacs on the lecture circuit as if they were 'trustworthy'?

This is one of my favourite quotes:


?The reactor has an amazing safety feature,? said Kirk Sorensen, a former NASA engineer at Teledyne Brown and a thorium expert. ?If it begins to overheat, a little plug melts and the salts drain into a pan. There is no need for computers, or the sort of electrical pumps that were crippled by the tsunami. The reactor saves itself,? he said.

-- Safe nuclear does exist, and China is leading the way with thorium (Contains similarly quotes from other 'experts'.)


This regarding China's nuclear plans in general: Leading physicist calls China's nuclear programme 'rash and unsafe'


You do have a track record ...


Can you back that up with an example or is this just you being you again?

Okay, done that.


The first is predictably evangelical and OTT, the second refers to uranium based nuclear power, not thorium.


The Chinese have to buy their uranium from Australia, with a very weak trading record. The anxiety is predictable, but not relevant to thorium.


It's important that we get away from just 'nuclear is bad', to recognising that there are different processes and fuels. 'Wind' isn't the same as 'Gas' even though it sounds similar.

Never mind the German mind-control cultists, if it were in my power, I would gift to you a subtle sense of humour and an internally fitted E-meter that vibrates whenever your plonker is pulled.


Alas, all I can do is wish you and yours a very Merry Christmas and a Healthy, Hilarious and Preposterous New Year :)

I was under the impression it was India leading the way with thorium, it has abundant supplies and, due to the non proliferation treaty, uranium has historically been in short supply.


Coincidentally I was reading about India's plans on this site recently and have just looked up China's. What struck me was looking at where the technology is coming from, the Chinese are mostly buying from the USA (Westinghouse) and France (Areva), India from Russia. The Canadians are heavily involved in thorium research, but UK plc? Nowhere to be seen.

US industry is becoming competitive again due to significantly reduced energy bills

US households getting a nice boost to incomes as shale gas reduces the average household bill by 20%

US will have less and less interest in the Middle East...this could be dangerous or good


...it's a game changer

alternatively, a man alone ;-)


I'm neutral on the subject btw - I'm not necessarily convinced by the doommongers but nor am I persuaded by evangelists.


Reaping the benefit of a power-source in a short term (historically speaking) appears to only have upsides - history says there will be "issues"


file me under "cautiously appreciative" on this one

This might give you a less gushing overview than the IEA one (they have been caught out several times before massaging and manipulating their figures)

http://www.chathamhouse.org/publications/papers/view/185311

The Klondike-like rush to shale gas has led to oversupply and significant decrease in price, which ironically makes the expensive process less economic. Investors are worried... The USA's sluggish economy has also helped consumers with their energy prices.


Shale gas was not a new technology but became economic due to the large oil price increases of 2006-08. It remains to be seen whether it's a long-term alternative to either coal or oil. If the USA wants to get back to a world of steady long-term growth, it won't become self-sufficient in energy - a situation that ironically can only likely happen with long-term economic stagnation and decline.


Not a game changer IMHO.

I think 'destroys argument' is rather hyperbolic, but some good points well said.

My main issue is that it so fundamentally detracts from any efforts to do anything about carbon reduction.

It's spectacularly expensive in carbon to produce, leave alone the fact that we suddenly have hundreds of years more reserves of carbon fuel, the impending peak of which was doing much to focus attention on alternatives.


This without the more conventional environmental damage it wreaks http://www.theguardian.com/environment/2013/aug/11/texas-tragedy-ample-oil-no-water

That,s just an emotive piece EP, not science or anything, I thought you believed in good science. Are all communities in the US anti franking, running out of water, jumping up and down in anger at their 20pc reduction in energy bills etc. Renewables are expensive,w ay over subsidised and years away from making a significant dent in our energy consumption gas and fracked oil are far better Environmentally than coal fired electricity...the debate lacks any rationality in most of them their circles that I get in trouble for going on about :) just FRACKING= BAD end of....sigh

what quids said.


govt's own target for 20% renewables by 2020 (which won't be met) leaves 80% to find from non-renewables which if we are not going to get by going down nuclear route leaves oil, gas or coal. and that's leaving aside the imbalance we get from wind (too much).

Glad yuo've made your mind up. How? I'm still trying to find objective evidence on which to base a decision. The former Government Chief Scientist David King has dismissed most of the concerns cited as irrational. Others tell me I'll be able to light the gas coming from my cold water tap. What is truth?

This is a quote from the Guardian article in EP's link:


But Katharine Hayhoe, a climate scientist at Texas Tech University in Lubbock, argues fracking is not the only reason Texas is going dry ? and nor is the drought. The latest shocks to the water system come after decades of overuse by ranchers, cotton farmers, and fast-growing thirsty cities.


"We have large urban centres sucking water out of west Texas to put on their lands. We have a huge agricultural community, and now we have fracking which is also using water," she said. And then there is climate change.


West Texas has a long history of recurring drought, but under climate change, the south-west has been experiencing record-breaking heatwaves, further drying out the soil and speeding the evaporation of water in lakes and reservoirs. Underground aquifers failed to regenerate. "What happens is that climate change comes on top and in many cases it can be the final straw that breaks the camel's back, but the camel is already overloaded," said Hayhoe.


The point about fracking is that the rational evidence suggests not that there are no drawbacks/negative effects, but that those that can be accurately measured e.g. chemical use are not particularly severe for what is, after all, an industrial process, and those that are reliant on risk analysis e.g. do not represent signficant risks. The economic argument in favour is unanswerable, at least in the short - medium term.


However, the argument is not just about science or economics but also politics, which is perfectly appropriate (science and economics might support eugenics, but most people don't).


The political argument against (at least insofar as it's not based on pretend science) is, as EP said, this:


"My main issue is that it so fundamentally detracts from any efforts to do anything about carbon reduction.", or to put it another way, cheaper fossil fuels lessen the incentives to seek (non-polluting) alternatives.


I can see the argument, but I'm not persuaded, for two reasons. Firstly, stopping fracking will mean more energy from dirtier and more expensive fossil fuels for a long time to come - a big loss for an uncertain future pay off. Secondly, the incentive for greater overall fuel efficiency will never go away (at least in a competitive market) and tbh I think market driven mechanisms are the only means by which human energy use is going to fundamentally change.

I'd take Sir David King's word over the reactionary opposition from those with vested interests anyday.


(Mind you, the Chief Scientist was always extremely pro-nuclear. Anything we do now in that respect is probably a bit 'too little, too late').

    • OK, I have been extremely stupid. This is a long and sorry saga, so unless you are into schadenfreude,  or know about laptops and might actually be able to help, you probably need to stop reading here. I got a new laptop last May, with a 2 year guarantee from John Lewis (that was my first mistake, but the laptop met all my requirements at a very good price). I hate OneDrive, and I  had been using Carbonite for backing up files.  When I got the new laptop, the files from my old laptop which had been backed up on Carbonite were downloaded onto it. For tedious reasons originally related to problems with my old laptop, files and folders were duplicated all over the place. Sorting this out wasn't top of my priorities. In an attempt to at least keep new files,  and files edited since I bought the laptop, in one place and completely separate from all the old duplicated  files, I saved them all into folders  on the SSD. However, I didn't restart the Carbonite backup, because my intention was to sort out all the duplicate files first. About a fortnight ago, I bought an external hard drive. My intention was to copy everything on the new laptop onto it before I started deleting any of the duplicate files. I hadn't done that yet because I had to finish doing my accounts and then do my online tax return. So the copying was next on my To Do list. The inevitable happened. Out of the blue, my laptop went into complete meltdown. I was editing a spreadsheet and went into settings to turn the brightness up. I checked the brightness was ok on the spreadsheet, came out of settings, and suddenly everything went black. I did all the obvious things, then googled other possible fixes, including specific to my laptop model, but nothing worked. On starting the laptop, the Lenovo logo came up, the little white circle turned round, the red light for face recognition flashed, then zilch.  But clearly it wasn't a problem with the physical screen, as it displayed the logo. It wouldn't start in safe mode either. I thought I might either have accidentally changed some setting, or else it might be connected with a recent update  I couldn't try some of the tests suggested, eg removing RAM, because anything involving physically unscrewing my laptop would invalidate the guarantee  I am a member of Which Tech, so I contacted them. Obviously their hands were rather tied as they couldn't connect remotely to the laptop as there was no display. They said I couldn't have clicked on some other setting by mistake, as the display section only related to the display. They said they thought it was probably an issue with either the operating system or the mother board, or a component of them. They said it should be possible to identify the fault without losing my data. Given the involvement of John Lewis, I said I thought this was unlikely, as they had once told me to do an unnecessary factory reset on my old laptop and told me this wouldn't lose my data, which I had queried at the time,  and had to pay me compensation. So at this point I phoned John Lewis, to be told a repair would take "up to 28 working days" and no they wouldn't supply a replacement laptop during that time. I decided to take the laptop to John Lewis rather than have it collected, so their tech people could look at it first. So then the JL tech person said I must have clicked on  Bitlocker by mistake and locked myself out out of the laptop. I thought this was highly unlikely. Anyway, pursuing this line of thought did not help, and she was still unable to get into it by putting in the Bitlocker code. So then we had the data saving conversation. She said the company the laptop would go to was approved by Lenovo. She said they would do a factory reset first regardless. I said could they not try to identify the fault first. She said no. I said could I not request that they did. She said no. She said I could pay £150 for data retrieval, which could be done first. She said it would require removing the hard drive. She said if anybody else did this it would invalidate the guarantee. So. I have brought the laptop home to think things over. But I'm not willing to pay £150,  because the important files I can reconstruct by other means, and I have hard copies of most of them, it's just a time consuming pain. I have contacted Carbonite to see if they have any way of backing up the non backed up data even though I can't get into the laptop. If you have managed to reach the end of this post, congratulations 🤣 and do you have any bright ideas? I have typed all this on my mobile. It has taken a very very long time 🤣

    • Off the top of my head, there are notice boards in Sainsbury's and the library where small businesses can advertise, not to overlook the internet and forums such as this which these days is where very many go to first for small business information. I find it strange that you are mounting this crusade to allow small businesses the right to advertise in the Community noticeboards when there are so many alternatives these days. As I said before, the Community noticeboards are too small to accommodate commercial notices and would probably overwhelm and obscure the NFP notices. For info, during the week there is just as broad a mix passing by the NXR boards as the one by the station
