Demonstration Results

The three-phase demonstration focused on test range applications. Phase 1 demonstrated that the TFF could be used to flash range material to a 5X level. Explosive-treated coupons were used to verify that explosive material would be eliminated by the flashing cycle. These coupons were sent to a laboratory for analysis following decontamination and found to be completely clean from explosive residue. In addition, an effective basket design was established to structurally withstand the heat, contain any molten aluminum created during the flashing cycle, and allow efficient heating of the material. Phase 2 demonstrated that the heat cycle does not vary significantly based on the density of the materials flashed. Phase 3 established operating parameters that would maximize throughput. Labor, materials, and cycle times were determined. A reliable heat soak cycle time also was developed that assures metal decontamination and eliminates the costs and problems associated with instrumenting each load. Emissions levels were tested to verify that they are insignificant and will have little or no impact on siting the TFF. As expected, all emissions were below established limits. Overall, the demonstration confirmed that the TFF can be used to decontaminate test range metal debris to a 5X level efficiently, effectively, and economically.
