  • Patent number: 8047978
    Abstract: A new High-Throughput Explosive Destruction System is disclosed. The new system is comprised of two side-by-side detonation containment vessels each comprising first and second halves that feed into a single agent treatment vessel. Both detonation containment vessels further comprise a surrounding ventilation facility. Moreover, the detonation containment vessels are designed to separate into two half-shells, wherein one shell can be moved axially away from the fixed, second half for ease of access and loading. The vessels are closed by means of a surrounding, clam-shell type locking seal mechanisms.

  • Patent number: 7495145
    Abstract: The invention provides methods and a reactor for safely destroying containers having toxic chemical and biological materials contained therein. The reactor comprises a pressure vessel having an internal reaction chamber and at least one heater disposed on an exterior of the pressure vessel. A fragment-suppression system is also disposed within the internal reaction chamber. The fragment-suppression system is adapted to receive a container therein, such as an energetic chemical munition, and is adapted to receive a charge for opening the container. An injection port is also provided so that oxidants can be injected into said reaction chamber to neutralize the chemical and biological materials after the container has been opened.

  • Patent number: 6881383
    Abstract: An explosive destruction system and method for safely destroying explosively configured chemical munitions. The system comprises a sealable, gas-tight explosive containment vessel, a fragment suppression system positioned in said vessel, and shaped charge means for accessing the interior of the munition when the munition is placed within the vessel and fragment suppression system. Also provided is a means for treatment and neutralization of the munition's chemical fills, and means for heating and agitating the contents of the vessel. The system is portable, rapidly deployable and provides the capability of explosively destroying and detoxifying chemical munitions within a gas-tight enclosure so that there is no venting of toxic or hazardous chemicals during detonation.
