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 .
Sodium compounds. Sodium atoms have 11 electrons, one more than the stable configuration of the noble gas neon. As a result, sodium usually forms ionic compounds involving the Na + cation. [1] Sodium is a reactive alkali metal and is much more stable in ionic compounds. It can also form intermetallic compounds and organosodium compounds.
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.
There are 20 isotopes of sodium ( 11 Na), ranging from 17. Na to 39. Na (except for the still-unknown 36 Na and 38 Na), [4] and two isomers ( 22m. Na and 24m. Na ). 23. Na is the only stable (and the only primordial) isotope. It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28(2).
Sodium periodate is an inorganic salt, composed of a sodium cation and the periodate anion.It may also be regarded as the sodium salt of periodic acid.Like many periodates, it can exist in two different forms: sodium metaperiodate (formula NaIO 4) and sodium orthoperiodate (normally Na 2 H 3 IO 6, but sometimes the fully reacted salt Na 5 IO 6).
Sodium-ion batteries ( NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na +) as their charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion.
This is especially the case for companies studying fast neutron reactors of 4th generation (molten salts reactors, metal-cooled reactors (sodium-cooled fast reactor, or lead-cooled fast reactor). Fast breeder reactors "burn" 235 U (0.7% of natural uranium), but also convert fertile materials such as 238 U (99.3% of natural uranium) into fissile 239
Sodium salts of certain aromatic sulfonic acids - particularly naphthalenesulfonic acid - are used in the preparation of azo dyes. Inorganic sodium salts. Examples of important inorganic sodium salts are sodium fluoride, sodium chloride, sodium bromide, sodium iodide, sodium sulfate, sodium bicarbonate and sodium carbonate.
