As things stand they may as well just stick with Uranium rods.

that's whole point you buffoon. technology will advance and solve the remaining minor issues with thorium power.

oh thats right you are a nut who thinks technology can't advance :wak:

"technology will advance", is some immaterial genie called progress that presides over the universe. No, such animal!

The ancient Greeks understood the principle of steam power. But it took 2000 years before the first steam pump was invented in the 1690's to pump water out of deep mines. It took another century for steam power to be applied directly to machinery. All this was made possible by advances in iron casting and iron sheet making.

Nuclear power has been here for over 60 years, but improvements have come at a snails pace. Presently a nuclear power unit can't be made very small, so forget cars. What Laser Power Systems will return for your investment dollar is the nuclear powered car with no engine.

Presently there no reason to use thorium in preference to Uranium, Thorium has very little in the way fissile material present, where as they process Uranium for the naturally fissile isotope. This leaves sheadloads of DU anyway.
The next trick of our glorious banks will be to charge us a fee for using net bank!!!

we just spent 3 pages explaining thorium is fertile, not fissile, and you just circle right back around without collecting $200 for passing go.

the rate of technological advancement is accelerating, it took a few thousand years from inventing the wheel to inventing the car, but it took less than 100 years to go from the car to the jet plane and to get to the moon.

And thorium requires a stream of neutrons from somewhere else to convert to fissile 233. Why bother digging up Thorium when there's already a million tons of DU on the worlds shelves?

again we are covering old ground.

thorium requires an initial source of neutrons. after that it can produce 20% more fissionable material than you put in.

Which is currently a pipe dream. A major issue is prepossessing spent rods, which is dangerous and presents difficulties because of the presence of "undesirable" isotopes. Currently there is a general ban on reprocessing. And 20% is drawing board, the plant concerned suffered from too many problems to achieve that. And it used uranium, not thorium. The plant was closed and the "spent" cores treated as waste.

Pig Iron, can you get anything right?.............you're beating the odds, you are always wrong.

your failure to read and comprehend the information andrew and i have shown you is not my failure - it's your own.

You seem unable to differentiate between a drawing board concept, a trial and a success. The success part hasn't happened yet!

Here is the state of play as i understand it.

1. A molten fuel thorium reactor has never been built

2. The molten fuel uranium reactor built as a mock up for thorium had some major project jeapordising issues with embrittlement of all surfaces in contact with the hot radioactive fuel that must be solved.

3. Reprocessing of fuel to extract fissile materials is not already being done on a big scale for Uranium suggesting economics does not favour it. Extracting U233 from Thorium should be easier though?

4. Even basic issues like dealing with fuel from ordinary reactors is not being addressed in the USA. There are no commercial reprocessing facilities there at all.

5. To some extent existing light water reactors are somewhat close to being breeders already - you still have to be able to reprocess the fuel.

6. The successful shippinghouse breeder had a 1100 tons of Uranium233 and 35 tons of Thorium - it worked but the fuel needs to be reprocessed to remove the uranium233 from the Thorium blanket and build the new U233+Thorium active core. The whole thing even if successful is a major hassle that is probably not justified by current oil and gas prices

How may 235 atoms were sacrificed to make the rods in the first place? :D
That's actually not relevant.

It's like saying "how much electricity did you have to sacrifice to start that petrol engine."
The truth will set you free. But first, it will piss you off.

Australian Property Forum is an economics and finance forum dedicated to discussion of Australian and global real estate markets and macroeconomics, including house prices, housing affordability, and the likelihood of a property crash. Is there an Australian housing bubble? Will house prices crash, boom or stagnate? Is the Australian property market a pyramid scheme or Ponzi scheme? Can house prices really rise forever? These are the questions we address on Australian Property Forum, the premier real estate site for property bears, bulls, investors, and speculators. Members may also discuss matters related to finance, modern monetary theory (MMT), debt deflation, cryptocurrencies like Bitcoin Ethereum and Ripple, property investing, landlords, tenants, debt consolidation, reverse home equity loans, the housing shortage, negative gearing, capital gains tax, land tax and macro prudential regulation.

Forum Rules: The main forum may be used to discuss property, politics, economics and finance, precious metals, crypto currency, debt management, generational divides, climate change, sustainability, alternative energy, environmental topics, human rights or social justice issues, and other topics on a case by case basis.
