By capitalizing on the properties of water above its critical point (374oC and 22.4 MPa for pure water),
supercritical water technology can potentially be exploited for both waste destruction and energy
generation. In the first case, Supercritical Water Oxidation (SCWO) provides rapid and complete
oxidation of organics, including chemical nerve agent, with high destruction efficiencies at typical
operating temperatures. In the second case, the Supercritical Water Cooled Reactor (SCWR) concept
promises high thermal efficiencies in combination with nuclear plant simplification. Both technologies,
nevertheless, involve significant materials issues.
