Not exact matches
Hence, engineers typically use a
liquid metal such as
sodium as a coolant and
heat transporter.
During the day, some of the oil is used to
heat a mixture of
liquid nitrate salts (made by combining elements like
sodium and potassium with nitric acid) to temperatures above 700 degrees Fahrenheit.
This ensures efficient transfer of
heat from the metal fuel to the
liquid sodium coolant.
The
heat from the primary
liquid sodium is transferred through the metal structure of the IHX to the
liquid sodium flowing through intermediate side.
The intermediate
liquid sodium is then circulated through another
heat exchanger called a steam generator.
Unlike the current generation of light - water nuclear reactors, PRISM uses metallic fuel, such as an alloy of zirconium, uranium, and plutonium, and PRISM's fuel rods sit in a bath of a
liquid metal —
sodium — at atmospheric pressure, which ensures that the transfer of
heat from the metal fuel to the
liquid sodium coolant is extremely efficient.
Thus,
liquid sodium is the coolant of choice in fast reactors because it can effectively transfer
heat away from the nuclear fuel, while at the same time maximizing the number of fast neutrons.
However, the IFR is, I believe, cooled with
liquid sodium, necessitating an extra
heat exchange loop for safety.
Solar thermal generation is where the reflectors are concentrated on a central receiver which then
heats a
liquid such as
sodium, which in turn
heats the water to generate steam that drives a turbine coupled to a generator.
