What is another word for liquid metal reactor?
Pronunciation: [lˈɪkwɪd mˈɛtə͡l ɹɪˈaktə] (IPA) 
A liquid metal reactor is a type of nuclear reactor that uses liquid metal as both a coolant and a neutron moderator. There are several synonyms for liquid metal reactor, including sodium-cooled fast reactor, lead-cooled fast reactor, and molten salt reactor. Sodium-cooled fast reactors utilize liquid sodium as the heat transfer medium and may have a high breeding ratio. Lead-cooled fast reactors use liquid lead as the coolant and may be suited for small-scale or off-grid power generation. Molten salt reactors use a liquid mixture of fluoride salts as the coolant and fuel, and may offer improved safety and waste management over traditional reactor designs.
