No new nukes for UK???

Fission dies the moment you switch off the photon beam. There are not enough neutrons for it continue of its own accord," he said." Since when have photons been neutrons? OK, Now I am Not a Nuclear Physicist BUT what I think happens is that high energy gamma rays - photons - or maybe its electrons or protons alpha particles - bash into thorium. It is stable BUT if you smash it hard enough you get slightly more out than you put in, and a few neutrons too. These an then be used to smash into other crap lying around - depleted uranium works I think, and when that goes pop, it fission decays into a smaller one if you hit it hard enough, with a net release of energy and the heavier it is, the easier it is, up to uranium-235 which is the heaviest naturally ocurring element. The rest we make. Likewise in principle any element lighter than iron can be fusioned, to make a heavier one and that also gives of energy. Iron is the most nuclear stable of the lot. Only uranium-235 as a natural element is capable of natural chain reactions. The heavier stuff has decayed.. (Ok radon which is as by product of uranium decay is also around, but only becasue teh uranim is) BUT stuff that's nearly as heavy as uranium or uranium 238 (ordinary depleted ****) will split quite easily IF you give it enough excess energy, and then you do ALMOST get a chain reaction. Its like trying to burn anthracite on a bonfire, with a bellows it works, but mostly it goes out. There's a lot more to it than that..moderators and coatings and stuff, but in principle it's megawatts in, gigawatts out, and if the megawatts fail the gigawatts stop almost instantly. I'd say there would still be some decay products, just not as many. Oddly enough, in a way its like fusion, in that you have to throw a lot of energy at it to get it going, but unlike fusion you don't need the immense pressures nor do o have the mmense temperatures sither. here's what wiki says/ Protobns, not photons. The energy amplifier uses a synchrotron or other appropriate accelerator (e.g. cyclotron, fixed-field alternating-gradient) to produce a beam of protons. These hit a heavy metal target such as lead, thorium or uranium and produce neutrons through the process of spallation. It might be possible to increase the neutron flux through the use of a neutron amplifier, a thin film of fissile material surrounding the spallation source; the use of neutron amplification in CANDU reactors has been proposed. While CANDU is a critical design, many of the concepts can be applied to a sub-critical system.[1][2] Thorium nuclei absorb neutrons, thus breeding fissile uranium-233, an isotope of uranium which is not found in nature. Moderated neutrons produce U-233 fission, releasing energy. This design is entirely plausible with currently available technology, but requires more study before it can be declared both practical and economical. (from the little I know about the subject) I know sod all, which is probably why I don't understand the above quote. |

And they would be sent into e.g. a lead target to generate neutrons. In fact the Indians are proposing to use a plutonium core in their reactors, which will produce the neutrons directly. That should astonish the Greenies' weak nerves. "You get a pot boiler and fill it with thorium and light it with a poker made of old bomb material Gets hot, and the punka wallah fans it into the boiler" "Then you open the regulator and off goes the train." |

As long is its a balanced intelligent review, I am all for it. 'balanced and intelligent' and 'environmental lobby' don't however fit in the same sentence. I'm afraid you are right. I don't know why. Perhaps it is the poor quality of much science training. I should know as I have worked in that area and seen how poor it has become. Or perhaps under-educated people have always had a problem with rigorous logic but now have a chance to spout their ill-thought-out ideas through the variety of mass-media available to them. If things were different, I would call myself an environmentalist, but I get depressed at the poverty of many of the opinions that are touted. One such area is genetic modification. Instinctively I am against it until proven safe. However GM soya, tomatoes and maize have now been eaten for a couple of decades without any apparent problems arising. I am happy to change my mind, as we certainly need speedy evolution of more hardy crops if we are not to starve. Not sure where she got it from but my wife was peering at a blog and muttering 'if they had educated the kids to do basic cost benefit analysis and science, instead of climate changes studies and teaching them how to screw in a CFL...' How very very true! |

It could lead to unforeseen results. But what doesn't? Rabbits in Australia, then myxmatosis.. The whole use of pesticides n the 60's. leading to dead raptors..the probable link between pesticides and falling bee populations. Science is amoral.

I've never been against GM per se, but it needs careful watching. It could lead to unforeseen results. GM makes profound changes to the very fundamentals of life, the DNA. It is a technology that has the potential for very dire consequences, as well as great benefits. The widespread introduction of said GM crops, before extensive testing as food on living beings, was a very dangerous experiment. Luckily we seem to have got away with it. Like Mengele's data, I don't approve of how it was done, but the data is priceless. But what doesn't? Rabbits in Australia, then myxmatosis.. The whole use of pesticides n the 60's. leading to dead raptors..the probable link between pesticides and falling bee populations. Rachel Carson's book, Silent Spring, was an eye-opener in the 60s or was it 50s? People were more trusting and ignorant then. We still make mistakes of course, but I think we're more open and informed now. Television has helped in bringing people's attention to these things, for example the destruction of coral reefs. Science is amoral. It needs to be *applied* morally if you want a moral result. The gathering and analysis of scientific knowledge is amoral I agree. Scientists are not though. Most think about the consequences of what they do. Many would like more say in decision-making and are disgusted when irrational decisions are made against the evidence, for example over recreational drugs. |

Indeed, but I'm not aware that anyone against GM ever came up with a sound reason that it might be bad for you. The tow arguments that I thought were valid were that it might go mad and breakout and take over habitats, and the exact reverse, it would be essentially sterile, and thereby leave people addicted to more GM seeds for their crops. |
