Molten salt reactors are nothing new. Proponents of nuclear energy say it could deliver just that, … ANSTO is the implementing agency for Australia. De ARE van Idaho National Laboratory gebruikte een eutectisch mengsel van natriumfluoride en zirkoniumfluoride als zout. In het verleden hebben in de Verenigde Staten twee experimentele gesmoltenzoutreactoren gefunctioneerd: het Aircraft Reactor Experiment (ARE) te Idaho en het Molten Salt Reactor Experiment (MSRE) te Oak Ridge, Tennessee. Molten Salt Reactor (MSR) technology was partly developed, including two demonstration reactors, in the 1950s and 1960s in the USA (Oak Ridge National Laboratory). It uses a molten salt as coolant and fuel. They are seen as a promising technology today principally as a thorium fuel cycle prospect or for using spent LWR fuel. One can speak of a veritable “fan club.” Among the positive features of this reactor type (see below) are its intrinsic safety features and its suitability for utilizing thorium as a fuel source. In dit project werkt de NRG nauw samen met JSR (Joint Research Centre) in Karlsruhe. Aan de MSBR heeft Oak Ridge National Laboratory gewerkt van 1970 tot 1976. Unlike conventional solid-fuel reactors MSRs use molten FLiBe salt solutions of nuclear fuel, and are actively cooled with molten Eutectic NaK alloy. The grand objective of the project is to deliver a breakthrough in nuclear safety and nuclear waste management to make nuclear energy truly safe and sustainable. While a traditional reactor may use up to 4% of the energy in their uranium fuel, the WAMSR utilizes 96% consequently reducing nuclear waste to 2.5% of what is produced by a typical reactor. Some of these companies pursue the development and near-future deployment of commercially-available MSR systems independently.

De splijtstof was uraniumtetrafluoride. Now, the European team is giving it another shot. Using nuclear techniques to sustain good health, Neutron Activation Analysis and Neutron irradiation. De gesmoltenzoutreactor wordt om die reden vaak gelijkgesteld aan de 'thoriumreactor', hoewel het gebruik van gesmolten zout en van thorium los van elkaar kunnen staan. This is demonstrated by the Energy Return on Investment (EROI) coefficient, which is simply a ratio of the energy output (Eout) and energy input (Ein). Government agencies were joined by a number of start-up companies, including Terra Power, Terrestrial Energy and Moltex, among others. Chinese onderzoekers in Sjanghai zijn van plan om rond 2020 een experimentele reactor gereed te hebben. Louis Qualls, Ph.D., is the national technical director for molten salt reactors for the US Department of Energy’s Office of Nuclear Energy and also serves as the reactor technology integration lead for the Oak Ridge National Laboratory Reactor and Nuclear Systems Division. The nuclear industry was the first to recognise the potential of molten-salt-based energy-generation systems in the 1950s during the U.S. Aircraft Nuclear Propulsion Program. With a rapidly evolving space industry, there is a renewed interest in MSR systems for nuclear electric propulsion, as well as extra-terrestrial surface power. The MCFR technology will utilize liquid salt as both fuel and coolant in the reactor core. This fully pumped molten salt loop tested key components including: pumps, heaters, freeze valves, flanges, and instrumentation over time. The high boiling point and low vapour pressure are of interest because of the operational safety of a molten-salt-based system at atmospheric pressure, and favourable heat transfer characteristics that enable efficient and economic energy transfer and storage. New Illawarra Rd, A molten salt and thorium reactors would be far more compact than current nuclear reactors and some designs would achieve almost no nuclear waste. And, owing to their inherent load-following capabilities, the proposed MSR systems provide unmatched operational flexibility given they can operate in remote areas as well as in existing complex electricity networks. Our design is smaller, simpler and inherently safe, making it low-cost to build and operate. Advanced nuclear reactors, such as molten salt-based reactors and very high-temperature reactors provide a viable option within a future mix of energy systems. De Amerikaanse onderzoekers richten zich op de 'molten salt cooled reactor', waarbij gesmolten zout wordt gebruikt in combinatie met vaste splijtstof.
