    Abstract: A method for remediating non-homogeneous radioactive waste to significantly reduce the waste mass/volume and to convert such waste to products that meet federal regulatory compliance standards is disclosed. High level waste (HLW) stored in underground tanks is typically a multi component mixture. After removal of the waste from the tanks or other storage areas the waste is isolated in a thermal desorption-type reaction vessel where the waste is pyrolized at pre-determined and carefully controlled temperatures, pressures, and atmospheres. This process eliminates organics, volatile metals, moisture and other low boiling temperature/high vapor pressure components and converts non-volatile waste to more stable metal oxides. Off-gas treatment systems scrub, treat and dispose of all off-gas components. A thermal desorption-type apparatus especially well suited for performing the method of the present invention is also disclosed.

    Abstract: A low-pollutant system for waste materials treatment includes a process chamber for converting organic components of the waste materials into a flammable gas and a two-stage vortex burning chamber for complete combustion of the flammable gas. The vortex burning chamber includes a first substantially-horizontal combustion chamber and a second substantially-vertical combustion chamber disposed at a right angle to each other and communicating therebetween. The first combustion chamber has an inlet portion for receiving the flammable combustion gas from the gas generator means for injecting primary air into the first combustion chamber, thereby forming a mixture of air and the flammable gas and thereby igniting the mixture for partial oxidation thereof. The first combustion chamber has a converging distal portion for discharging the partially-oxidized mixture of air and the flammable gas tangentially into the second combustion chamber, where the gas is mixed with the secondary air which is injected tangentially into the second combustion chamber, thereby substantially completely oxidizing the partially-oxidized mixture of air and the flammable gas. The second combustion chamber has an outlet portion for discharge of the waste gas resulting from the two-stage combustion of the flammable gas and the solids separated from the gas.

    Abstract: A multi-step process is provided in which waste material is processed in two or more steps. Specifically, an earlier step of the process heats the waste material at a first temperature. This results in a release of vapors for materials having a boiling point that is lower than the first temperature. A subsequent step of the process heats some or all of the remaining waste material at a second temperature, which is preferably higher than the first temperature. The subsequent heating results in a release of additional vapors for those materials having a boiling point that is lower than the second temperature. A system configured to carry out the process is also disclosed.
