    The molten-salt reactor built in the US back in the 60s had a maximum output of 7MW thermal -- it never generated any electricity, the heat was dumped to air. A modern GenIII uranium reactor like those coming on-stream in China and elsewhere produces about 4500MW thermal /1600MW of electricity 24 hours a day, and with downtime for refuelling, inspection and maintenance as needed they are expected to operate for sixty years at least -- a century of operation is not impossible given the extreme overengineering that goes into the core components involved.

    It's a bit like saying someone who built a model aircraft engine that ran for a few hours means they can design a reliable efficient cost-effective truck engine based on the same principles. Good luck with that.

    As for the proposed Indian thorium reactors they are basically standard PWRs and heavy-water BWRs fuelled with a mixture of thorium, medium-enriched uranium and plutonium derived from conventional low-enriched uranium nuclear reactors of the sort in operation around the world today. Thorium (Th-232) isn't a good nuclear fuel by itself, it needs to be bred into fissile U-233 with neutrons from U-235 and Pu-239/240 before its energy can be extracted. India want to go this route because they're not signatories to the Non-Proliferation Treaty and therefore limited in their access to the world's nuclear materials markets and they don't have good native sources of uranium ore. If it were otherwise they probably wouldn't bother.

    The bit about decommissioning costs being paid for by the government is a lie. Nuclear power plants in the West build and maintain a reserve fund to pay for end-of-life decommissioning, usually based on a percentage of the cost of the electricity generated and sold. In the US that's 0.1c to 0.2c per kWh IIRC.

    Government taxpayers only pay for decommissioning non-power reactors such as the ones used to make weapons-grade cores for bombs etc. Decommissioning power reactors is paid for by the electricity consumer in the end. This isn't particularly onerous -- France's electricity consumers pay about 13c Euro per kWh for their nuclear generated electricity and that includes a decommissioning levy. Germany's electricity generated by lignite coal and Russian gas and a small amount of renewables costs twice that much to the consumer while it emits nearly twice as much carbon per kWh generated.

    As for construction costs being paid for by the governnment, that's untrue as well -- there may be loan guarantees from a given government but those loans to pay for the upfront costs of building the reactors are commercial financial instruments, meant to be paid off over forty years and more of the reactor operating and generating sellable electricity. I don't actually know of a Solyndra-style billion-buck default on a loan guarantee for a nuclear construction project.

    You are correct about the cost of fuel being a minor part of nuclear operations though. Thorium is a solution looking for a problem, basically -- there's lots of uranium around, it's dirt cheap, so cheap that major sources can't be economically exploited yet since they're in very remote areas of the world and getting them to market would be more expensive than they're worth.

    The research into using thorium is very long-term. Centuries from now when uranium becomes scarcer thorium might become the go-to non-carbon fuel but right now it's only an interesting laboratory curiosity.

    Good grief, what an utterly crap article! So many things they got wrong... Lessee, the thorium experiment involves eight (8) pellets of mixed-oxide thorium/plutonium fuel in a single fuel rod loaded into a low-powered heavy-water research reactor fuelled mostly with enriched uranium (the reactor is designed to accept other fuel elements like the thorium MOX rod for testing purposes which is why the test is being carried out in Norway). Thorium needs a neutron flux to breed Th232 up into fissile U233 and produce energy hence the mixed-oxide formulation of the pellets mentioned. Assuming the MOX pellets get commoditised they'll need an ongoing future supply of Pu to continue making them and that can come only from either reprocessing fuel rods from regular uranium reactors of the type running today or breeder reactors also burning uranium although the track record of breeders hasn't been too good up till now, lots of engineering problems with molten sodium leaking and consequential fires. Note that the travelling-wave reactor design mentioned in the original article is basically a breeder using guess what? as a coolant. Oops.

    I want a preservative made without mercury

    And I want a pony.

    There is piss-all evidence that thimerosal is harmful in any way to anyone, pretty much, with a track record going back 80 years of intensive use as a preservative for vaccines. There might be an allergic reaction to thimerosal in some folks but at concentrations way above the small amount that exists in vaccines and such reactions are usually minor, as in skin testing. The notable byproducts of the small amount of the original tiny amount that is broken down in the body are mostly ethylmercury which has very little effect on the human body even at much higher dosages than would result from its use in a one-off injection or even a series of vaccinations given over several months. Methylmercury is created in even tinier amounts compared to the miniscule amounts of ethylmercury produced by breakdown.

    So why are you so down on Thimerosal? Let me guess, it's the mercury molecule. Science, research, testing, analysis, decades of use and billions of thimerosal-preservative vaccinations and they all mean nothing in the face of anecdotal naturopathic detoxification woowoo and snake-oil salesmen with books to sell.

    and there are alternatives today which are just as good which meet that description

    Is there any proof of this statement? Decades of results showing no systematic adverse reactions, no reduction of the efficacy of the vaccine, low cost, effectiveness, storage time, patents (thimerosal is so old it's totally generic by now), availability etc. etc. Thimerosal has all these proven benefits, the new preservatives don't but you're willing to take a blind leap of religious faith and have billions of people follow you because... of that Hg molecule which you don't like.

    I want a preservative made without mercury,

    You've got your wish. Thimerosal is no longer used for pediatric vaccination in the West, in fact it hasn't been for over ten years because of woowoo and Jenny Bloody McCarthy and Andrew Fucking Wakefield and the uninformed adherents of crystal power and chakras and Himalayan Salt. It's still used in a few adult vaccinations like seasonal flu jabs because it's much better than the alternatives, it's cheaper, easier to produce, protects vaccines for longer than the expensive patented preservatives currently in use and we know it works really well. It's also used in third-world countries who can't afford Himalayan Salt but who really need a good vaccine preservative and who can't afford to placate the worshippers of woowoo like yourself.

    I don't get everything I want.

    Actually in this case you did. You're still thrashing around on the floor in a tantrum, face blue from holding your breath because your wish came true a decade ago and you were having such a good time feeling oppressed and angry about that Damn Molecule of Mercury you couldn't hear the good news.

    Thanks for insulting me. Now I can take the safeties off the weapons.

    Did you really mean to say that out loud? Deary deary me.

    Thimerosal has been shown to break down inside the body in exactly the way it isn't supposed to.

    If it breaks down at all (most of it is excreted intact over a period of a few days or weeks) it forms ethylmercury which is not exactly harmless but is not particularly potent. Methylmercury is a lot nastier and anti-vaccination loons often don't or won't realise the difference a single letter makes in a chemical compound name hence the fluff and fluster from ill-informed folks like yourself.

    And the chlorine in salt isn't the kind of chlorine that's really harmful, which is why what you're saying is fucking hilarious.

    ORLY? What kind of not-really-harmful chlorine are you referring to? All isotopes of Cl are equally poisonous in elemental form and there are no other alternative forms of chlorine in the universe (well, my universe at least. I don't know what it's like where you come from). In table salt the Cl atom is bound very closely to a sodium atom, in Thimerosal the Hg atom is linked to a sulphur atom and an ethyl group, the latter of which results in ethylmercury if the molecule breaks at the sulphur bond. If there is a pathway to produce methylmercury it doesn't seem to be common or prevalent before the byproducts get excreted.

    you can't comprehend that Thimerosal isn't the only preservative available.

    It's a very good preservative for the specific job of preventing lots of deaths and injury from contaminated bulk vaccine -- see for example the incident (referred to in the Google article about Thimerosal) in 1928 when a batch of contaminated diptheria vaccine killed 12 children out of 21 treated. Thimerosal doesn't affect the vaccine which in many cases is basically a low-grade infection as far as the body is concerned, a soup of protein coats and killed viruses that antiseptics are designed to destroy. Thimerosal is well-proven with a long track record of not being deleterious to the population being vaccinated. What more could you want?

    The standard reply to the Thimerosal nuts like you is "it's OK to eat some sodium and breathe some chlorine because eating table salt won't kill you."

    Thimerosal (officially called Thiomersal) is an organometallic compound in the same way NaCl is a compound and as such the mercury atom is bonded to the rest of the molecule, not roaming around loose in the solution. Mercury is magical juju to the anti-vaccine crowd, a curseword that kills and maims because of its name and nothing more.

    Thimerosal been in use as an antiseptic and antifungal agent in vaccines for about 80 years now, preventing death and injury from bulk vaccines unwittingly contaminated by assorted dangerous bugs and without affecting the vaccine's potency as other antiseptic compounds do. It's now being withdrawn from use because of unfounded panic and overabundance of caution and I confidently expect more deaths and illnesses in the future because of that. Good work, fella!
