what is salt fuel
The fuel salt is circulated through a heat exchanger where it is cooled by another molten salt loop that is free of radioactive fuel and fission products. The heat from this second loop can be used to do work, such as heating water to turn a steam turbine to generate electricity. molten salt reactor (MSR) is a type of nuclear reactor that uses liquid fuel instead of the solid fuel rods used in conventional nuclear reactors. Using liquid fuel provides many advantages in safety and simplicity of design. Generation IV roadmap published by US Department of Energy.
