... . Because hydrolysis destroys agents and active energetics, the resulting hydrolysates pose a lesser hazard than the assembled chemical weapons.l This finding is independent of any subsequent secondary treatment steps that will be necessary to render the hydrolysates environmentally acceptable.

... It destroys chemical agent to a 99.9999 percent DRE and energetic materials to a 99.999 DRE by mediated electrochemical oxidation, provided that the following safeguards are observed: hydrocyclones are used on all slurry feed streams, high-shear vortex mixers are used, —piping design minimizes dead legs, and all sys tem equipment and piping use trace heating to prevent precipitation of energetic intermedi ates, and a second set of electrochemical cells is used to polish the anolyte to the required destruction level. · It produces acceptable slurry compositions for processing burster energetics and rocket propel lants.

... If it is resolved, the committee believes that the Eco Logic package could provide an effective and safe means for destroying the assembled chemical weapons. However, the following design features still require validation: Design of the overhead conveyor system for the caustic bath should be tested to demonstrate satisfactory reliability.

... It is expected that weapons processing at Blue Grass will require no SCWO liner changes for the SCWO reactors treating energetics hydrolysates and dunnage slurried in energetics hydrolysates. For each of the two operating reactors used to treat agent hydrolysates, the technology provider has scheduled six liner changes that are estimated to be necessary for treatment of GB hydrolysate (i.e., 12 liner changes total for the GB campaign)
