Does anyone know if any of these issues have been addressed? See their whitepaper. Molten salt reactors use fuel dissolved in a molten fluoride or chloride salt which functions as both the reactor's fuel and its coolant. There is growing awareness that nuclear energy is needed to complement intermittent energy sources and to avoid pollution from fossil fuels. One of the unique benefits of a thorium reactor is that it can be mixed with current nuclear wastes that are produced. These thorium reactor pros and cons prove that there is a lot of potential in this technology. Molten salt reactors (MSRs) use molten fluoride salts as primary coolant, at low pressure. In a fuel salt reactor, just one drop of fuel salt leaking from a valve or pump seal, will be so radioactive, that you won't be able to send workers within 50 feet of the valve, even if you drain and flush the whole reactor first. Unlike all current nuclear reactors, the fuel is in liquid form. Molten salt reactors (MSRs) are a Generation IV nuclear reactor that use molten salts (high temperature liquid salts) as their nuclear fuel in place of the conventional solid fuels used in the world's current reactors. This means that such a reactor could not suffer from a loss of coolant leading to a meltdown. The lithium is highly enriched in Li-7. This material produces high levels of dangerous gamma rays, even if certain nuclear threats are eliminated. Since the fuel salt is liquid, it can be both the fuel (producing the heat) and the coolant (transporting the heat to the power plant). HOWEVER I will try to stick strictly to molten salt VS molten metal and try to leave the molten fuel VS molten coolant and solid fuel out of my response. Molten salt reactors are nuclear's future, but there's still a lot we don't know. Misconception #6: Thorium reactors and Molten Salt Reactors are the same thing! 7. The benefit of a thorium reactor is that just one ton of this element can produce as much energy as an estimated 200 tons of uranium. Press question mark to learn the rest of the keyboard shortcuts. Current estimates for nuclear storage are up to 100,000 years of maintenance. Emission of gamma rays: Presence of Uranium-232 in irradiated thorium or thorium based fuels in large amounts is one of the major disadvantages of thorium nuclear power reactors. I copied the following bullet points from this Wikipedia article. As Argonne explains it, when an atom in a nuclear reactor “fissions”—or splits into several smaller fragments—neutrons are released at high energy (fast speeds). It may also reduce the need for long-term storage as the technology for reusing fuels is improved. Yes, in various flavors of solution. For example, Reactive IVS, a company in Denmark, is developing a molten salt waste-burner (MSW) that is designed to use nuclear waste from conventional nuclear reactors as a fuel. The fuel for molten salt reactors is already in a liquid form as well, so the threat of a meltdown emergency is eliminated. The potential of a thorium reactor is this: it could provide enough clean energy for every person, community, and nation on our planet. On larger scales, a consortium of countries including Japan, the U.S., and Russia is working on the Fuji MSR, which will be a 100 to 200 MW reactor upon completion. Thorium is safer to mine. Little development compared to most Gen IV designs. Oak Ridge National Laboratory ran molten salt thorium reactor experiments from the 1960s until 1976. 4. The technology is promising in terms of safety and economy and has the potential to avoid the release of long-lived radioactive waste in the case of severe accidents.
