    With the very high conversion ratios, we have enough Uranium in our spent nuclear fuel "waste" stockpiles to provide ALL human energy needs for at least 50 years. This is really amazing. That "waste" that everyone is afraid of is just sitting there in cooling ponds waiting to eliminate all coal burning if we would just wake up and use it.

    These molten salt reactors are extremely promising. We really made a big mistake as a country when we funded the liquid metal fast breeder reactor program and shut down the MSR. It is clear that MSR is much safer, cheaper, and more feasible than LMFBR.

    We should consider adding research and SMR test reactors onto existing generation sites, in that way the heat could be used to generate heat for profit and all the other existing facilities would already be in existence and otherwise fully licensed, as would necessary personnel and other aspects. Test reactors could also come in handy to substitute for existing reactors scheduled to be taken off line for fueling or other maintenance. In this manner, the heat output would start generating revenue on day one of its operation!

    i don't understand why the spheroid reactor is too small. Size doesn't matter. Power doesn't matter. What matters is the cost measured in dollars per watt. A smaller reactor lends itself better to serial production (assembly lines). Bonus points if it fits in a standard shipping container. doesn't matter if it's 1 MW for 2 million bucks or 100 MW for 200 million bucks.

    @MillyVanillification No, the difference between a 10,000 year "store elsewhere" requirement and a 300 or 500-year "store elsewhere" requirement is a really big difference. 500 years is doable, we can bury things with 500-year containment enclosures. I don't think anybody ever took 10,000 years seriously as even remotely do-able. Plus the amount of waste is orders of magnitude smaller. I really think this deserves some serious consideration.

    May I suggest that we limit the workers to only use hand tools, this way the work will be slower per person and more jobs will be needed to get the required energy. :)
    All facetiousness aside, it is generally better to get more end product for less work, so if the end product we want is energy, then we want to get the required energy with the fewest jobs. This way people can work on using the energy to create goods instead. Cheers.

    This may be better than concentrated solar thermal power with (liquid salts ... again) heat storage!
    I prefer the expansive "cover the deserts with mirrors (not black PV) idea" only because it seems that with the diffuse nature of solar, many thousands of times more jobs would be created. Of course because of that, energy costs would be more. Would that be the solution to the melting economy? (Need an economists to answer that one).

    A power plant is basically impossible to make in to dirty bomb of any kind. And even if they steal the material it's not that easy to do it. Cars release more dangerous particles every day than any dirty bomb could.

    That depends on how much you value energy independence. China has vowed to have a proof of concept operating in 2017 and a commercial MSR 5 years later. They currently have 300+ scientists working on this with a budget (I believe) of $2M annually. The Chinese would likely be willing to lease (or franchise) this tech to the western nations - for the right price.
