This reactor would be different from today's reactors in almost every aspect. Different fuel. Different coolant. Different approach to safety. Different approach to fissile security. What goes into the reactor is different. What comes out is different.



This gives people a new perspective on nuclear. What people assumed was the only approach is no longer the case. We can start asking, what do we want from nuclear power? ...instead of take-it or leave-it. ► Thorium is a mildly radioactive metal which can be turned into nuclear fuel inside a Thorium Reactor, and then fissioned to produce both energy and valuable isotopes.This reactor would be different from today's reactors in almost every aspect.

Thorium Molten-Salt Reactor helps us replace engineered-and-redundant safety systems with passive ones which always work. Passive safety systems based on the laws of physics, not robust and redundant equpiment.



Statistically, over the 60 years we've had civilian nuclear power, it has always been the safest form of energy production. By raising "safety" as a feature of Thorium Reactors, many supporters of nuclear power see Thorium as a solution to a problem which does not exist.



But I'd ask you to dive into the safety-case regardless. We've had 3 major nuclear accidents in those 60 years. In all 3, the conventional reactor choice of water as coolant played a role. ► Perhaps the starkest contrast with conventional reactors is how the Molten-Salt in ahelps us replace engineered-and-redundant safety systems with passive ones which.

To-date, civilian nuclear waste has sat in cooling pools and dry-cask storage. It harms no-one, but there it is. Those spent fuel rods contain Uranium, Plutonium and Fission Products. Many people find this to be troubling.



In contrast, a Thorium Molten-Salt Reactor can be designed to produce nothing more than Fission Products. Thorium goes in. Fission Products come out. Per unit of power, an incredibly small volume of waste compared to today's reactors. Also, valuable. Because for all Plutonium which many people would prefer remains trapped in those spent fuel rods. Just as safety isn't seen as a "problem" by the nuclear industry (because the current fleet is statistically safe) some of the Thorium Molten-Salt Reactor's features are also seen as solving problems which aren't really problems.To-date, civilian nuclear waste has sat in cooling pools and dry-cask storage.

could we be doing with our spent fuel rods, our "Nuclear Waste?" ► Whatwe be doing with our spent fuel rods, our "Nuclear Waste?"

We could keep spent fuel rods in Dry Cask storage. Already, many nuclear power plants feature a collection of dry casks near the reactor. They sit there, doing nothing. But they do present a barrier to remediating retired power plants. (Assuming a new reactor can't simply be built right next to the retired one, making the very same site suitable for continued housing of the dry casks.)



We could move spend fuel into a geological repository. California prohibits the construction of new nuclear power until the question of spent fuel has been addressed. So this is one way to deal with political challenges facing nuclear power, deal with non-fuel-rod nuclear waste (such as radioactive hardware like pipes), and deal with the actual spent fuel rods themselves. Yucca Mountain storage is opposed by Nancy Pelosi (and Nevada voters), so the only way to remove the political risk from this approach is to pursue multiple geological storage sites in parallel.



Or, we could, if we so wanted... recycle the spent fuel rods. In fact, spent fuel pellets are mostly (93%) un-fissioned uranium. This neither dangerous, nor valuable, nor fuel for a Thorium Reactor. It simply constitutes the bulk tonnage of what is nuclear waste, making the problem seem bigger than it really is. The useful stuff, and the hazerdous stuff, is diluted by the uranium. Without unfissioned uranium, we'd have a waste story that looks more like France.

France's decision to build a nuclear fleet was made in 1974, and by 1990 they succeeded in decarbonizing their electricity supply (as well as transitioning most household heating from fossil-fuel to electricity). Would you like to address Global Warming? This is how you address Global Warming... with 1980s technology.





The reason France's nuclear waste takes up so little space, is because they chemically reprocess their fuel. Their spent fuel (just like ours) consisted of spent fuel rods... solids. To reprocesses they dissolve the solid fuel into liquid form, and then separate the materials. Most of what can be fissioned goes back into the reactors.



In the French version of this, enormous amounts of transport and infrastructure are involved. France (just like us) uses a fuel form-factor not well suited for recycling. In fact, any solid-fuel nuclear power plant is ill-suited for recycling. That is why Oak Ridge National Lab built the Molten Salt Reactor Experiment: to validate the concept of dissolving nuclear fuel into a liquid, so we could finally add online chemistry to our nuclear toolbox. ► So what could we do with 2020 technology based upon the long-neglected Thorium Molten-Salt Reactor concept?

absolutely depends on the development of online chemistry tools. That was the concept behind It is the development of such chemical tools, for a Molten-Salt environment, which makes the Thorium Molten-Salt Reactor unique. The Thorium Molten-Salt Reactor, to run exclusively on Thorium fuel,. That was the concept behind ORNL-4528 in 1968, and it wasn't until 2016 that those challenges finally started to receive funding.

Yang's 2027 date serves as an indicator how serious he is about seeing Thorium Reactors through. Any further into the future, and he would be trusting his successor to continue funding development. Any further into the future, and he would be communicating "this will be someone else's problem to ultimately solve." There's an implication here, that a President Andrew Yang will monitor progress, and help ensure bureaucratic delays are minimized.



Perhaps the most decisive factor as to whether Thorium Reactors are built during Yang's time in office, is how quickly the first $10 million (million, not billion!) are allocated. That is because much of the chemistry research is... Inexpensive. Ridiculously inexpensive .

The seemingly overlooked aspect of Yang's plan to fund Thorium Molten-Salt Reactors, is that the $50 Billion is also to be shared with Fusion Power research as well. Molten-Salts are the technical overlap. Salt pumps, monitoring of salt chemsirty, salt purification, salt heat exchangers, and power conversion systems to turn hot salt into electricity... this R&D budget for advanced atomic power solutions (Thorium and Fusion) doesn't just move us forward on the most exciting concepts. There's a world of Molten-Salt approaches (which are closer to commercializaton) which also benifit.

But, a President making Molten-Salt research a national priority is a prerequesite for any 2027 Thorium goal. Regardless how easy/hard some challenges prove to be, by pursuing Thorium Molten-Salt Reactor research, 2027 will see very exciting, passively safe, high temperature and carbon-free energy solutions. ► Andrew Yang proposes that with $50 Billion in federal funding we will see such reactors brought online by 2027.

And if we could extactly replicate "The Sun in a bottle", keep in mind our Sun emits enough radiation to heat Earth only because it is large enough for 1,300,000 Earths to fit inside. The actual energy density of our entire Sun is 1/400,000th of the 1965 Molten-Salt Reactor Experiment. The Sun is powerful because it is large, not because of its energy density.



Should we ever be capable of a net-positive sustained energy production from a Fusion Reactor, then we'll need to fuel it (by creating Tritium), and we'll need to protect the vessel from neutron radiation. FLiBe Molten-Salt offers a solution to both looming challenges.



Both the Thorium Reactor and a Fusion Reactor make use of a "breeder blanket". This is a surrounding layer of FLiBe Molten-Salt used to absorb the neutron radiation and turn some of the salt content into fuel.



Thorium Reactors do this by dissolving Thorium in the blanket salt. Thorium, once struck by a neutron, evolves into Uranium-233. On-line chemistry moves U-233 from the blanket salt into the core salt, refueling the core so that nuclear fission can be sustained.



Fusion Reactors do this by using FLiBe salt with identical chemical properties, but a different isotope of Lithium. This Li-6 isotope neede for Fusion Reactors is more likely to be struck by neutrons than the Li-7 in Thorium Reactors. It is the Li-6 (and Beryllium) in the Fusion-salt-blanket which create Tritium (fuel for Fusion) when struck by neutrons.
