What if the next big thing in nuclear energy was a dusty old idea from the Cold War era? Once considered to power nuclear bombers, molten salt reactors (MSRs) are in the spotlight, promising safer, ...

To meet energy demands and reestablish the nation’s energy dominance, U.S. companies are developing several types of advanced reactors. One type of advanced reactor, a molten salt reactor, uses fuels ...

Researchers at Oak Ridge National Laboratory used advanced experimental methods to measure heat transfer and flow in molten salts, filling a data gap that has constrained MSR reactor design and ...

The Idaho National Laboratory (INL) has cleared a major hurdle in making a Generation IV nuclear reactor practical. Using a new process, a team has developed a new way of processing fuel efficiently ...

The first stage of design work on a prototype molten salt reactor has been completed, Russian state nuclear corporation Rosatom has said. (Image: Rosatom) A preliminary design was unveiled in February ...

Nuclear technology firm Terrestrial Energy has quietly been making progress on its Integral Molten Salt Reactor (IMSR) technology, laying the crucial groundwork for a commercial fleet by the early ...

China has unveiled plans for a massive nuclear floating island, which will be fueled ...

Idaho National Laboratory (INL) has debuted a new molten salt test loop that will support the development of advanced reactors using molten salts. The Molten Salt Flow Loop Test Bed is meant to allow ...

Naarea, a French developer of a molten salt fast neutron microreactor, announced it has successfully demonstrated an innovative proliferation-resistant pyrochemical method of producing sodium chloride ...

Scientists have built the first-ever thorium reactor. Thorium is both more easily accessible and less dangerous than uranium—the most common fission fuel. The system also uses molten salt instead of ...

Molten Salt Reactors (MSRs) are nuclear fission reactors in which either the fuel and/or the coolant is a molten salt. Molten salt is salt which liquifies at elevated temperatures and can store ...
