Apr 8, 2024 · Initially developed as part of the Aircraft Reactor Experiment in the 1950s, ORNL then ran a trial known as the Molten-Salt Reactor Experiment (MSRE) from 1965 to 1969, operating an experimental 7.34 MW (th) MSR. The project established proof of concept for reactors powered by liquid fuel and cooled by molten salts.

Nov 24, 2023 · Molten salt reactors (MSRs) are seen in some countries as a promising advanced reactor technology because of the various benefits associated with them. They operate at higher temperatures, which lead to increased efficiencies in generating electricity. In addition, low operating pressures can reduce the risk of a large break and loss of coolant as a result of an accident, thereby enhancing the ...

Written to assist individuals in academia and industry and in relevant regulatory and policy roles, this publication provides a summary of the current knowledge on the status of research, technological developments, reactor designs and experiments in the area of advanced reactors that are fuelled or cooled by a molten salt.

Aug 24, 2020 · Molten salt reactors (MSRs) may play a key role in future nuclear energy systems by offering major advantages in safety and efficiency. Advanced research, technology development and licensing in several countries can potentially make near-term deployment of this innovative technology possible.

Nov 9, 2016 · Molten salt reactor technology has attracted private funding over the last few years, and several reactor concepts are under development. One area under research is the compatibility between the salt coolant and the structural materials and, for some designs, the chemical processes related to the associated fuel cycle, Monti said.

Aug 27, 2020 · Description There is growing interest in Member States in molten salt reactor (MSR) technology, with development of these innovative reactors ramping up over the last decade. Many MSR designs offer unique advantages, including in the areas of safety and economics. Many also are being designed to operate at higher temperatures than most currently operating reactors, making them more suited for ...

A four-year IAEA coordinated research project focused on the possibilities of developing thorium-based nuclear energy, examining the benefits and the challenges of using thorium as a fuel and analysing its application in different types of reactors — from the most commonly deployed water cooled reactors to molten salt reactors.

Aug 29, 2018 · Spotlight on Innovation: Molten Salt Reactors for a Sustainable Clean Energy Transition News Story 29 August 2018

Mar 13, 2023 · Thorium boasts several advantages over the conventional nuclear fuel, uranium-235. Thorium can generate more fissile material (uranium-233) than it consumes while fuelling a water-cooled or molten-salt reactor. According to estimates, the Earth's upper crust contains an average of 10.5 parts per million (ppm) of thorium, compared with about 3 ppm of uranium. “Because of its abundance and its ...

It presents new data, or verifies existing data on, thermo-physical properties of liquid metal and molten salt coolants, and describes tools for on-line monitoring and control of coolant chemistry. Methods to improve the corrosion resistance between heavy liquid metal coolant and components, structure material and instrumentation are also examined.
