EBR-I used a liquid metal alloy, NaK, for cooling. NaK is liquid at room temperature. Liquid metal cooling is also used in most fast neutron reactors including fast breeder reactors such as the Integral Fast Reactor. Many Generation IV reactors studied are liquid metal cooled: Sodium-cooled fast reactor (SFR) Lead-cooled fast reactor

The integral fast reactor (IFR), originally the advanced liquid-metal reactor (ALMR), is a design for a nuclear reactor using fast neutrons and no neutron moderator (a "fast" reactor). IFRs can breed more fuel and are distinguished by a nuclear fuel cycle that uses reprocessing via electrorefining at the reactor site.
Schematic diagram showing the difference between the loop and pool designs of a liquid metal fast breeder reactor. The pool-type has greater thermal inertia to changes in temperature, which therefore gives more time to shut down/SCRAM during a loss of coolant accident situation. The reactor is a pool type LMFBR with
The RAPID-L design is a liquid metal fast breeder reactor (LMFBR) concept meant to prevent accidents due to human errors. The goal was to create a long-life core that is inherently safe due to being maintenance free. These were necessary requirements as the reactor was intended to be used on the Moon. [1] [3] [4]
The concept is generally very similar to sodium-cooled fast reactor, and most liquid-metal fast reactors have used sodium instead of lead. Few lead-cooled reactors have been constructed, except for some Soviet nuclear submarine reactors in the 1970s, but a number of proposed and one in construction new nuclear reactor designs are lead-cooled.
The project was intended as a prototype and demonstration for building a class of such reactors, called Liquid Metal Fast Breeder Reactors (LMFBR), in the United States. The project was first authorized in 1970. [4] After initial appropriations were provided in 1972, work continued until the U.S. Congress terminated funding on October 26, 1983 ...
One patent has been obtained, [3] and another is pending on the liquid metal fuel variant. [4] The reactor design won the public vote for the Galileo Knowledge Prize in the German GreenTec Awards of 2013, although the award committee presiding over the awards changed the rules to exclude nuclear designs before announcing the winner. Dual Fluid ...
