From page 31...
... A vertical cylindrical reactor is the only reactor configuration that has been successfully demonstrated to date at pilot scale for the treatment of VX hydrolysate and similar waste streams. Additional development and pilot-scale testing of SCWO technology will be necessary to ensure sustained, reliable operation of a full-scale integrated treatment system.

From page 32...
... A basis for the reliable scale-up and operation of SCWO technology for the treatment of VX hydrolysate has not yet been demonstrated. Fundamental knowledge about the following processes within the SCWO reactor is still not available: · the number and characteristics of the physical phases, including large quantities of entrained and adhered solids and potentially liquid, gas, and supercritical fluid phases · fluid dynamics and mixing processes complicated by relatively high loadings of insoluble salts heterogeneous and homogeneous reaction mechanisms and kinetics · salt nucleation, particle growth, agglomeration and adhesion mechanisms, and kinetics .

... Requirements for process destruction efficiencies and final disposal standards for all effluent streams from SCWO treatment should be clearly defined to ensure that the final design meets regulatory standards. 33 REFERENCE NRC (National Research Council)
