  • Kirk Sorensen stumbled across thorium while doing research on how to power a lunar community. Thorium is a cleaner, safer, and more abundant nuclear fuel-one that Kirk believes will revolutionize how we produce our energy.
    Kirk Sorensen began his work with thorium while working as an aerospace engineer at NASA. In 2010, he left NASA to work as the chief nuclear technologist at Teledyne Brown Engineering. In 2011, he founded Flibe, a company focused on developing modular thorium reactors.

      The part that he doesn't tell is that thorium reactor has to be a breeder reactor by design thus making it a potential factory of uranium-233 which can be weaponized after brief concentration. That's actually why US choose to go with boring reactors. Those conventional reactors can't breed nuclear fuels thus making it easier to share it with other country without constantly checking over their shoulders.

    Hi Kirk, Thorium Reactors and Desalination Plants should be built on ships that are nearing the end of their use by date .
    They can be moored in any port that is experiencing drought and draw salt water straight out of the harbour.
    If the drought breaks they can be moved to another port that is experiencing drought.
    Excess electricity can be fed into the city's electricity grid.
    Fresh water can be pumped into the city's water mains, it would have the effect of increasing the holding capacity of rain water dams.
    Salt that is recovered in the process is a valuable commodity, it can be on sold to industry.
    A fleet of these ships could be greening the world.
    Imagine the number of new jobs this industry would create.

      I read up on these and so this talk or a similar one 5 or 6 years ago pricked my memo on this.
      The reason enriched uranium was chose is alluded to here as the reason thorium was ditched in favour of weapons grade uranium, Mmmmmm.

    Two numbers that are often misunderstood in this debate: First, dropping the bombs on Japan likely saved about 2 million lives, most of them civilian, by eliminating the need to invade. If you don't believe this, research Saipan and Okinawa.
    Secondly, I recently learned that at Fukushima, there were about 10 times as many casualties directly related to the evacuation, as to the radiation released. The death toll at Chernobyl was likewise overestimated. In both cases, these were OLD technology like cars without seatbelts and anti-lock brakes, compared to what he's talking about. Thorium reactors can't melt down, if they fail, they fail to safe.

    When we have Thorium nuclear reactors up and running, I vote that we award Gorden with the Nobel Peace Prize for his tireless efforts to inform the world about this technology. No longer will we war with one another over energy resources, like oil. By the time our Thorium supplies are critically low, surely we'll have fusion nuclear reactors.

In eliminating that also eliminates most of the transuranic isotopes which result when U-238 captures neutrons; namely plutonium and other long-lived isotopes. That leaves the fission products, which mainly have half-lives in the 30-year-or-less range.

    I have extremely high hopes for a Thorium Fission Reactor. I believe I heard India and France are currently building such reactors. I also was told that they can't meltdown and produce negligible waste, thus need a fraction of the room that current reactors (when I say this, I usually am picturing Palo Verde. As it's much closer to me than any other) need. Which would mean that densely populated areas could have their own nuclear power plants. With online shopping quickly killing off local shopping, especially specialty stores, many malls are being abandoned. With Thorium's ability to cool itself, it wouldn't take much retrofitting (relatively) to drop a Thorium Reactor into these abandoned shopping malls. And then the city has it's very own personal high quality power source. And while some cities will be afraid of this (here in Phoenix, where our only natural disaster is soul-crushing heat in the summer, we have next to nothing to worry about when it comes to possible threats to nuclear plants. And people will always associate nuclear plants with meltdowns, even if it's an impossibility), others with a greater quantity of repurposable buildings, like Detroit's old auto factories, can host the plants for said cities for a fee. Would create jobs and significantly improve the economy in that poor city. This large-scale increase in electricity will not only create jobs, but it can sever our dependence on foreign oil permanently. Obviously, it will be hard to sever our dependence on fossil fuels completely, but such a drastic reduction would make it to where we can supply our own demand. Everyone could drive electric cars. With the advancements in battery and supercapacitor technologies, that industry is poised for a giant leap forward, and for market dominance. Electric motors are known for fantastic torque. The new Tesla Roadster is the fastest (technically quickest, but without an Autobahn, that has more value) automobile. Tesla has a new battery plant, graphene advancements are coming by the bucket, it may not be front-page news (gossip is far more important sadly), but electronics are advancing faster than ever from production to consumption

      ​@@screamingnutbag7955 You must be referring to Dresden unit 1. A BWR which was the first ever commercially built and operated reactor. Unit one was again designed more as an early experiment, not designed to be the most powerful or profitable, but to test the abilities of a dual stream BWR that would be capable of load following on the grid.A solid fuel, the reactor was therfore not cappable of harnessing any of thorium's unique properties.
      This was similar to the other solid fuel thorium reactor that was built for civilian us, Shippingport, the first PWR reactor ever made for civilian use. The sole goal of was to achieve a relatively low output of power, and figure out the techniques and requirements of running a civilian reactor. As clearly explained to the public by the lead of the project "Right now, nuclear power is an art. We want to turn it into a science". Shippingport was never designed to be cheap or efficient, it was literally ripped from a military submarine reactor to learn how to do nuclear power. The thorium was in a solid fuel form, and thus could not take any advantage of thorium's natural breeding abilitites. Despite this and the solid nature of the fuel, Shippingport still managed to end up with more fuel in the core than was imputed before its shutdown, thereby proving the capability of thorium as an effective breeder if given the proper environment.

    I was shocked to hear this, and to realize it's real science.
    Pleased, but shocked.

    Gawd, if I had money I would help. I really studied the Thorium fuel cycle, and the designs of the Thorium, liquid metal reactor. I've got a few ideas on how to do this as well. It really, really needs to be developed, and tested. We now have the technology, even though, the previous thorium, burner, breeder reactors previous, have worked very well.
    We really really need to research and develop this technology,
    I would love to help.

    I have a friend who is a Nuclear physicist. He works on power plants. I asked him if any of this was true in Tedex tal. He says YUP .Totally !!. Everyone in the biz knows about it since its inception, its just the masses have no clue. Its because the military wanted and still always need the Toxic damaging elements of depleted uranium for weapons. On the surface in Governmental and geopolitical, they promote using it for power stations to power the world . That is why ALL the nations that have this type of uranium power stations also use it for military . depleted Urunium it was and still is the main product needed for weapons, electric power is the spin-off , NOT the other way around. The masses he says are lead to believe uranium is used for electric power stations mainly he told me. He said hey " that stuff pays me a great wage packet " he said . " War is a money racket he said "

    @johnbrown9439 5 лет назад +58

    He does not describe any of the engineering, which is the weak point with thorium. Current reactors rely on the proliferation of neutrons to create heat. The great thing here is that you just have to drop a few control rods that slow the neutrons right down, to turn the reactor off. A thorium reactor, in contrast, generates heat by gamma radiation. It is normally started with a neutron-gun, but that is not the source of most of the heat. Instead, isotopes are created which emit gamma, and these isotopes have a half-life of 20 minutes. So if you turn the neutron-gun off, the reactor will still generate heat until the isotopes have all decayed, which is days or even weeks later. The safety feature they all enthuse about is that without the excess of neutrons, the heat generation will eventually stop. The so-called "China Syndrome" is eliminated.
    But all current designs use the molten thorium not just as a heat source, but the means by which you get the heat out of the reactor, by passing it through a heat exchanger, to generate steam that then powers the turbines. In a conventional water-cooled reactor these pipes contain virtually clean water, which never rises above 200C. No shielding is needed, and in Fukushima, ersatz cooling was obtained in the explosive-damaged reactor by spraying water onto the outside of the pipes. But in current thorium reactors, the pipes are full of melted thorium at 1000C which is full of hard gamma sources, so they have to be surrounded by lead or concrete. You are not going to dissipate the heat fast enough by spraying water. In fact that would probably crack the shielding and maybe even the pipes. You certainly could not dare to let firemen close enough to spray, since they would receive huge radiation doses. So no fall-back cooling.
    They make a big thing of "dumping the reactor vessel's contents so passive cooling can take place". But it is at 1000C, well above the temperature at which steel loses its strength (remember the twin towers). You are going to have to build a huge metal pan out of exotic high-temperature steels. And the convective air-flow will be enormous, to get rid of around 1GW of heat for days or even weeks. The turbulence caused in the surface of the molten thorium will probably cause particles to be vented to the atmosphere.
    The only advantages of thorium that I can see are that it can be found right around the globe, and the reactor cannot be used to generate uranium or plutonium that could be used to make a bomb.

      Thanks John for this factual addition from the angle of power engineering. I think this is very relevant to understand all the aspects of Thorium`s application.
      Does it also mean that claims about converting conventional nuclear reactors/plants into Thorium-fuelled are unfounded?
      Could someone also confirm or debunk the following claims PRO Thorium:
      1. Thorium fuelling technology could have much better efficiency compared to the lower single digit % of the current ones;
      2. Partially also as a result of this plus the huge natural resources of it Thorium could last up to for the next 2 thousand years of mankind or so;
      3. Thorium -fuel produces nuclear wastes/residuals, which have signifantly shorter `half-lifes` i.e. waste disposal and storage would be more manageable, simply "cleaner", which has been a major counter-argument for conventional nuclear power generation?
      (disclaimer: I do not want to pose as an armechair expert here, this is what I just gathered elsewhere and earlier, for I would like to verify it with the help of someone competent...)

      @RentableSocks 5 лет назад +16

      john it's an important distinction that the thorium fuel is dissolved in a fluoride, or other salt. This is NOT molten thorium.
      Also, you don't need to let firemen close to it because there's no need. if the reactor is out of control (operating too hot) or you lose power, the fuel salt drains into a tank and returns to being sub-critical. There is no high pressure loop to explode, no danger of radioactive material flying all over the place in a disaster situation.

      Thank you for being the first person to ever list the real challenges of Fluoride salt Thorium reactors or whatever they call them these days. Most people debunking Thorium power write for idiots. What you write gives one something to think about. What you say about the low temperature of water coming out of a Light Water, or any solid fuel reactor, is one of the reasons a better technology needs to be found. Coal burning power plants are running at over 370 degrees to produce supercritical steam. As long as nuclear power is pretty much a novelty, ultimate efficiency isn't a big deal, but if there should be a renaissance in nuclear power, efficiency and the abundance of fuel are going to be important.
      I do not think these problems you mention are fatal, but Thorium reactors always did sound too good to be true. Still, the big problem is the amount of resources the coal and gas industry will use against any competition.
