Experimental investigations on carbonation of sodium aerosol generated from sodium fire in the context of fast reactor safety

Hygroscopic Growth and Phase Transitions of Na2CO3 and Mixed Na2CO3/Li2CO3 Particles: Influence of Li2CO3 on Phase Transitions of Na2CO3 and Formation of LiNaCO3

“…Meng et al estimated the gas–aerosol partition equilibrium of carbonates including CO 2 (g), CO 2 (aq), HCO 3 – , CO 3 2– , Na 2 CO 3 (s), and so on. The CO 2 uptake by atmospheric aerosols and ocean surfaces has been proposed, producing CO 3 2– through hydration and Na 2 CO 3 in the presence of Na + . − Furthermore, the indoor sodium fire generated in the sodium-cooled fast neutron reactor might cause the release of sodium oxide aerosols in accidental conditions, which ultimately lead to sodium carbonate by reacting with water vapor and subsequent combination with atmospheric CO 2 . − The transformation of sodium oxides into carbonates may accidentally become one of the sources of sodium carbonate present in atmospheric aerosols. In addition, salt lakes are widely distributed in the west of China with abundant Li + , K + , Na + , B 4 O 7 2– , CO 3 2– , Cl – , and SO 4 2– in the brines. , The climate in this region is usually windy and arid, causing great evaporation of lake water .…”
