Title: A nuclear Australia Post by mellie on Aug 14th, 2010 at 8:47pm
U.S. AEC, forerunner of the U.S. Nuclear Regulatory Commission and the United States Department of Energy spoke of electricity in the future being "too cheap to meter, this might be what's holding us back.
Cant impose a tax on what doesn't exist, ETS wise, now can we. We could always impose a fresh air tax (FAT) or something I guess... Ironically, since 2007, we have seen a sharp decline in new nuclear plants being added to the grid, 2008 being the first year ever whereby none were added, and only 1 or two (from memory) were added to the grid during 2009. Even stranger, some countries formerly pro-nuclear appear to be closing their plants down, for no apparent reason at all. 8-) |

It's not strange - it's obvious. It is too expensive and unpredictable and more advanced countries than us are embracing green technology. Even China is making an effort. Besides the nuclear lobbyists aren't getting the financial support they're used to since the sub-prime crisis hit the US. Let's hope it's a dying industry. |

With a determination to go green and cut emissions the USA has resumed development of nuclear power generation after thirty years of no new stations.
And why not. Pres Obama says a few kilograms of uranium is better than 30 million barrels of oil and there are no emissions at all. Who could argue with that. |

Following in the path of their predecessors, doesn't mean that previous leaders weren't being led by the World Order down that path also. As much as I hate using the term World Order - there's no other way to describe these organisations. Howard was as much of a puppet as Gillard or Rudd, the difference being Howard had a more important role to fulfill because his co-operation was needed in the instigation of wars and trade agreements.
Certainly it has been noted that 12 of Obama's appointments to the Whitehouse are members of the Trilateral Commission. |

Let us hope we have enough natural resources left to power our own nuclear plants if/when the time comes.
Bare in mind, we have been supplying the world with uranium for decades now. It would be a bummer to learn that we don't even have enough to sustain our own clear future, for when the time comes. :) |

There are a few concerns with it however...one being the technology isn't quite ready for commercial use here in Australia, also the potential for weapon mobilisation concerning it's by products as the thorium fuel cycle creates 233U, which, if separated from the reactor's fuel, can be used for making nuclear weapons and it's ongoing interests in countries currently investing more research into it than others such as India where there's more of it than any other place in the world, (we being second most abundant) abundance of it is of interest, China again missing out, so they are pretty well stuffed, and would be in pursuit of this substance I would assume. It's worth a thought, but has our technology advanced enough for commercial use? No not in the foreseeable future, least not for another 20 or so years+. India are still only in the research/test phase of commercial production. Thorium continues to be a tanatalising possibility for use in nuclear power reactors, though for many years India has been the only sponsor of major research efforts to use it. Other endeavours include the development of the Radkowsky Thorium Reactor concept being carried out by US company Thorium Power (now Lightbridge Corporation) with Russian collaboration. In mid-2009, AECL signed agreements with three Chinese entities to develop and demonstrate the use of thorium fuel in the Candu reactors at Qinshan in China. Another mid-2009 agreement, between Areva and Lightbridge Corporation, was for assessing the use of thorium fuel in Areva's EPR, drawing upon earlier research. Thorium can also be used in Generation IV and other advanced nuclear fuel cycle systems. http://www.world-nuclear.org/info/inf62.html With uranium beginning to deplete, it's hardly surprising why China want to invest in our country. 8-) Not even a centuries worth left of uranium hu!! ::) |

Mantras right, it's not a viable commercial prospect at present, is more a generation IV fuel.
Far time Australia caught up with it's own mineral technology though, because if we don't, some other nation will, and we will be deplete supplying the rest of the world their generation IV fuels, whilst rubbing sticks together trying to generate our own in kangaroo skins. 8-) |

Title: Re: A nuclear Australia Post by mellie on Aug 14th, 2010 at 11:32pm
Bob...
Power reactors Much experience has been gained in thorium-based fuel in power reactors around the world, some using high-enriched uranium (HEU) as the main fuel: #The 300 MWe THTR (Thorium High Temperature Reactor) reactor in Germany was developed from the AVR and operated between 1983 and 1989 with 674,000 pebbles, over half containing Th/HEU fuel (the rest graphite moderator and some neutron absorbers). These were continuously recycled on load and on average the fuel passed six times through the core. #The Fort St Vrain reactor was the only commercial thorium-fuelled nuclear plant in the USA, also developed from the AVR in Germany, and operated 1976-1989. It was a high-temperature (700°C), graphite-moderated, helium-cooled reactor with a Th/HEU fuel designed to operate at 842 MWth (330 MWe). The fuel was in microspheres of thorium carbide and Th/U-235 carbide coated with silicon oxide and pyrolytic carbon to retain fission products. It was arranged in hexagonal columns ('prisms') rather than as pebbles. Almost 25 tonnes of thorium was used in fuel for the reactor, and this achieved 170,000 MWd/t burn-up. #Thorium-based fuel for PWRs was investigated at the Shippingport reactor in the USA (discussed in the section below on the Light Water Breeder Reactor). #In India, thorium has been used for power flattening in the initial cores of the two Kakrapar pressurised heavy water reactors (PHWRs). The 60 MWe Lingen Boiling Water Reactor (BWR) in Germany utilised Th/Pu-based fuel test elements. -------------------------------------------------- So Bob, it's still in it's relative infancy, and not quite commercially viable in it's entirety yet. In India, thorium has only been used for power flattening in the initial cores of the two Kakrapar pressurised heavy water reactors (PHWRs)...so.... not quite there yet. Had we planned on burning coal for the next 70 years until our uranium depleted, then convert to this then "hopefully" commercially-ready thorium reactor? 8-) |

Whatever you want to believe. We should be building & learning about Thorium reactors here in Australia. Instead India is way ahead. The science is OK - it's engineering problems that can be overcome with enough time & money. We have great reserves of Thorium in Australia. If we also have the technology - we could have it all. The world will be paying us. It could also end coal fired power stations. We aren't leaders in it because our governments are all useless. The amount of money labor wasted on the BER could have paid for many safe Thorium reactors. If we owned the Thorium & the technology we'd be incredibly rich in Australia. |

Title: Re: A nuclear Australia Post by mellie on Aug 14th, 2010 at 11:40pm
But thanks for introducing us to thorium none the less Bob, and yes, it's definitely something to think about, this and work towards commercial use and HOPEFULLY preserve/hoard, this opposed to depleting it before we have even started using it like we did our uranium.

Well guys & gals.
We need people with vision in Australia. WE need to start a Thorium reactor & mining industry which we can sell to the world. This is hard to organise - it would be like the Manhatten Project. Certainly people like labor who couldn't organise some school buildings & some Pink Batts couldn't do it. We would need to buy up the best scientists from India & elsewhere to help us. It could be done but we need vision. |

I thoroughly agree, and given by the time we get our finger out and rub two pieces of uranium together to generate electricity, we will definitely require an alternative, as like Mantra said, we are already close to being depleted, no thanks to our wasteful archaic ways. It's definitely a viable future reactor fuel, perhaps we should start now, this opposed to being left behind again? ::) I just wish we could make the switch now, (over to uranium-nuclear until the time comes to make the switch to thorium)...because by then, our nuclear plants will be due for replacing anyway, and perhaps with your suggested alternative? .... Can our environment wait another 30 years of our burning coal is what I'm asking? Personally, I think it will come at a cost if we do. |

Because there are only 4 or so thorium plants in the world, all of which are in their relative infancy, phase of combined fuel production/development (power generating wise), this and it will be difficult convincing Australians to go with a less tested product than a more tried and tested Uranium fuelled reactor. I mean, we are bad enough 'levitating' to something other countries have been safely using for decades, can you imagine the blood draining from the sceptics faces and financial backing from our investors wallets if we start talking futuristic generation IV Thorium reactors without the technology being power-generating commercially ready? We haven't even evolved to uranium yet, and it's only just now we are taking a shine to the idea. They will flip, and rightfully so, because having it commercially ready could take another 20 to 30 years, when we could just go uranium nuclear tomorrow if we liked. I think India would like us to go for it, because it will mean our developing the technology for them to take advantage of with their own thorium resources when the time comes... I think we should bare this in mind also. Till then, we should work towards investing in a variety of renewable alternatives, along with uranium I think, because like uranium, eventually thorium will deplete eventually also, this is if we don't sell it to China first. See, we are a slow people here in Oz... well, a majority of us are anyway. I guess what i'm saying is why place all our eggs in the one basket, when eventually, this basket wont last anyway? 8-) |

Uranium fission reactors are already avaliable as packages. They are tried and tested. If we are going to go this way, we need to build one new reactor for every mainland state every 5 years from 2020. One of the advantages of Thorium for Australia is that we have the world's biggest Thorium reserves. Thorium has far fewer waste issues than Uranium, and could be a replacement technology for Uranium by 2050. Sir lastnail wrote on Aug 15th, 2010 at 12:23am:

Going on your figures of 30 years required to get the engineering right we could have a viable reactor in 9 years time.

Australia should move to nuclear power generation, esp or first in Vic and SA where very dirty brown coal is burned. But with Gen 4 fast breeder reactors.
Secondly, we could make a motza taking the world’s high grade nuclear waste for storage in the exhausted Broken Hill lead mines. would benefit Pt Pirie where the stuff can be unloaded and Broken Hill. Eventually we will need more renewable energy: nuclear fusion would be good but when will it be commercially rolled out? Secondly, solar energy but collected in space where we can get intense, uninterrupted sunlight. |

Title: Re: A nuclear Australia Post by DARWIN on Aug 15th, 2010 at 5:17pm
Uranium is not that abundant. If every country switched to nuclear there is maybe 30 years supply and no guarantee fusion will be ready then.
Thorium is a much better bet as are breeder reactors. |
