Supercritical water use in energetic - Corrosion issues

Supercritical water (SCW) is water at conditions above the critical point (typically 600°C, 25 MPa). SCW is used as coolant in the primary circuit of one of the new concepts of nuclear reactors. Supercritical water has unique properties and very low price enables its use as chemical environment as well as reactant taking part in chemical reactions. These reactions lead to very interesting products (i.e. nanocrystals). SCW can be use for toxic waste elimination, or as medium for biomass gasification.
