China Starts Molten Salt Nuclear Reactor Project

greg_barton writes "The Energy From Thorium blog reports, 'The People's Republic of China has initiated a research and development project in thorium molten-salt reactor technology. It was announced in the Chinese Academy of Sciences annual conference on Tuesday, January 25.' The liquid-fluoride thorium reactor is an alternative reactor design that 1) burns existing nuclear waste, 2) uses abundant thorium as a base fuel, 3) produces far less toxic, shorter-lived waste than existing designs, and 4) can be mass produced, run unattended for years, and installed underground for safety."

    Well that and the conflation of defense-industry nuclear materials production with energy production -- thorium reactors are almost certainly better for generating power, but they don't help you build nuclear bombs, so they get less funding (or at least they have historically).

    Especially since we have an estimate 400k tonnes of the stuff at $80/kg mined. I like the fact that this salt bath solution in that it is passively safe in that heat distorts the geometry slowing reaction rates and also they can drain the bath into subcritical loads quite easily (and I'd imagine you could make the drain plug out of a material that would melt above your normal reaction temp but well below critical level).

    Blame Reagan.

    Note how in 1980 all non-defense govt r&d dropped precipitously. Then during the 90s when oil dropped to $10/barrel and the free market abandoned alternative energy research, govt had the perfect opportunity to fulfill its role of investing in the kind of long-term disruptive research biz is too short-sighted to do - but govt didn't.

    Indeed. You can even make it from the salt itself. Just by cooling a plug of it in the drain. The original US experimental reactor worked that way. A simple fan cooled the drain plug. When the reactor lost power, the fan would stop, the plug would melt and the reactor would stop. That's no theory either, it was how the reactor was routinely shut down during the weekends. They just pulled the plug and went home!

    Eisenhower - who remains the only US president to reduce military spending. Also coined the phrase "the military/industrial complex".
    Backed the Marshall plan - he hated hitler and the nazi's but ended up quite liking the germans.
    Had another few notable foreign policy acheivements, such as ending the Korean war and refusing point blank to get involved in Vietnam because he knew that the US couldn't win there and besides sympathised with the vietnamese wanting to cast off French rule.
    Was probably the single most popular man in the world due to WWII - he was all but worshipped in Europe, had decent relations with Russian leaders and was largely respected everywhere else.
    Pushed HARD for a common european defence force, but the french nixed that (and de Gaulle insulted him and the American soldiers who'd fought to liberate France). Was the commander in chief of the compromise - NATO.
    He also tried for a worldwide atomic research agency and nuclear weapons treaties with Russia, but that fell apart when the U2 spy plane was shot down in the last months of his presidency. It was one of his great regrets that he authorised that flight, but anti communist fever was sweeping the US at the time and the CIA insisted that they needed it.

    Those that followed undid all his work so quickly it was shameful leading to the 60's which had the Bay of Pigs, the Cuban Missile crisis, the Vietnam war, the nuclear and conventional arms race and numerous other proxy wars. They spent the considerable capital that their soldiers and leaders like Marshall and Eisenhower had built up as if it was water. Shame, really.
