He's been told that glassification has been being done in the UK for 20 years but pretends he's never heard of it. As glass is quite stable and is not likely to be eroded or damaged until the planet melts in 500 million years time, it could just be left to itself. The obvious answer is indeed to put it in an ocean trench, where over aeons it will be subducted into the mantle, to join all the other radioactive material that's already there. If it were actually that dangerous. The more studies are done, the more the answer seems to be that radiation is 100 to 1000 times less dangerous at low levels, than the regulations imply. -- Everything you read in newspapers is absolutely true, except for the rare story of which you happen to have first-hand knowledge. €“ Erwin Knoll |

What is a "near fact"? I assume in near fact is one where they claim the cost of fossil fuels will rise, because or scarcity because fossil fuels get mined and mines DO run out of coal or it gets more difficult to mine it, that was true 50 years ago. That once coal gets as 'rare' as gold the cost of buying it goes up, just like the cost of a gold ingot. But remmeber once coals burnt it's gone as a source of possible power. |

With this disposal, the waste produced by one power plant in one year would eventually cause an average total of 0.6 fatalities, spread out over many millions of years, by contaminating seafood. Incidentally, this disposal technique would do no harm to ocean ecology. In fact, if all the world's electricity were produced by nuclear power and all the waste generated for the next hundred years were dumped in the ocean, the radiation dose to sea animals would never be increased by as much as 1% above its present level from natural radioactivity. So another one who has no answers to the disposal od nuclear waste. Everything is simple to the simpleminded. The text quoted by you is an answer to the disposal of nuclear waste. Perhaps I'm being simpleminded, but it is much preferable to being a complete idiot. harry is in la-la land, with his fingers in his ears.

Why do you supposeglass is stable even for five thousand years? If it were soeasy it would bebeing done. And it isn't. Just another half wit "academic" dismissing the problem because they don'tknow what to do aboutit. BTW how do you "turm nuclear waste into glass"? |

You are not alone. Gasification? There is a big debate as to whether nuclear waste in geological storage should be easily retrievable or not. |

They are worth keeping, but there are some medium to long term transuranics and unstable isotopes that are not much use really and in pretty small quantities. Just enough to give harry dhobi-itch, that's all. At the moment glassification is the best way, or they might be burnt in a special purpose reactor. Not a lot of energy in the fission though so less a fuel than a sort of damp cardboard. e.g. Gasification and stored in underground caverns in granite or such like. -- Everything you read in newspapers is absolutely true, except for the rare story of which you happen to have first-hand knowledge. €“ Erwin Knoll |

The rest is nothing new. harry, what *would* you accept as an answer to your perceived problem with nuclear waste? You seem to reject every solution that is linked to, so you must presumably have a better idea. While you're at it, maybe you could come up with a solution for the environmental damage and excess CO2 emissions caused by your favoured intermittent power generating solutions. There isn't one. That is the exact problem. And there have been failed permanent storage attempts where there has been leakage. https://en.wikipedia.org/wiki/Deep_g..._certain_sites And there has been "breeder" reactors that don't work. And there are proposed thorium reactors that produce much less waste. Only now being designed in India (of all places) I suppose you could launch it into the sun, but that would hardly be practicable. At the proposed Hinkley point reactor,they are just going to store the unprocessed waste because (a) they want to dodge the cost of processing (b) they don't know what to do with the waste after processing anyway. http://news.yahoo.com/cooper-nrc-no-...ZJUFVLMTNfMQ-- They are watching others, hoping a (low cost?) solution will emerge. https://en.wikipedia.org/wiki/Meuse/...rch_Laboratory No signs of it in fifty odd years. There will be a need for efficient generation of electricity/micro CHP from gas for years. Both in the home or in central power ststions but it can only be regarded as a temporary fix. http://www.energysavingtrust.org.uk/...heat-and-power You should be thinking about this now. It will take decades to set up a total renewable electricity system |

Introduction This paper is a response to what the author considers are not opinions, but near facts, with respect to the ongoing use of fossil fuels: namely that, irrespective of any climate change implications, the world is, if not running out of fossil fuels, running into an area characterised by high costs of fossil fuels, and that a transition to alternatives to fossil fuels, as the alternatives become cost competitive, is inevitable. yes they will as the cost of using fossil fuel's increase. i.e coal and oil will get so expensive it will be just as expensive as renewable energy then the answer is obvious don;t use either use nuclear as that will be the cheapest, and as we build more nukes effecincy is likely to increase bringing the costs down, unlike renewable or rare fossil fuel. What is a "near fact"? I assume in near fact is one where they claim the cost of fossil fuels will rise, because or scarcity because fossil fuels get mined and mines DO run out of coal or it gets more difficult to mine it, that was true 50 years ago. That once coal gets as 'rare' as gold the cost of buying it goes up, just like the cost of a gold ingot. But remmeber once coals burnt it's gone as a source of possible power. Something is either a facto r it isn't. It's a conjecture. |

Unfortunately, there are international treaties that prohibit doing that. The US and the UK can declare war on each other. Then each can sail merchant ships full of the stuff over the trenches. These ships can be sunk by the other side's subs. One war every 10 years should do it, followed each time by treaties of eternal friendship. Or we could sell it to the Russians, who will just sink with it anyway. How many russky nuke subs are down there? and how much radioactive dross did they dump? http://bellona.org/news/nuclear-issu...led-begin-week "According to NRPA, a catalogue of waste in the Kara Sea released in 2012 includes 19 ships containing radioactive waste; 14 nuclear reactors, including five that still contain spent nuclear fuel; 735 other pieces of radioactively contaminated heavy machinery; 17,000 containers of radioactive waste, and the K-27 nuclear submarine."
