Sodium-cooled fast reactor - Wikipedia
网页A sodium-cooled fast reactor is a fast neutron reactor cooled by liquid sodium. The initials SFR in particular refer to two Generation IV reactor proposals, one based on existing liquid metal cooled reactor (LMFR) technology using mixed oxide fuel (MOX), and one based on the metal-fueled integral fast reactor.
Can Sodium Save Nuclear Power? - Scientific American
网页2014年10月13日 · Liquid sodium is better than water at evacuating heat from the reactor core and its high boiling point of about 900 degrees Celsius allows SFRs to operate close to atmospheric pressure, negating...
Sodium - Wikipedia
网页Sodium is a chemical element; it has symbol Na (from Neo-Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds.
Liquid Sodium - an overview | ScienceDirect Topics
网页Liquid sodium is currently used in the Russian BN-600 and BN-800 reactors—the only ones operating SFRs so far in the world—and is proposed to be used in Generation IV SFRs. Sodium is a well-known low-melting-point (97.7°C) alkali metal, which has the main advantages of high thermal conductivity and low neutron absorption cross-section.
