    Abstract: A urethane based polymer composition is provided that exhibits superior shielding properties during and after exposure to high level radiation. The composite is formed by mixing a liquid isocyanate monomer, preferably 4,4′-diisocyanate monomer with a liquid phenolic resin, preferably phenol formaldehyde resin, and a phosphate ester flame retardant. An optional pyridine catalyst may be added to shorten the cure time. The resulting composition cures at room temperature and can be utilized in several manners, including spraying or pouring the composition prior to curing over radioactive material to prevent leakage of radiation. The uncured composite can be sprayed on the walls of a room or container to prevent leakage of radiation and can also be used to contain radiation prior to demolition. The uncured composite can also be molded into bricks or panels for use in construction. In a preferred embodiment, the polymer composition further incorporates radioactive waste, namely depleted uranium oxide, and can be used in conjunction with specially designed containers for storing radioactive material. The resulting polymer/waste composition cures at room temperature and does not deteriorate or suffer structural damage when exposed to higher levels of gamma radiation, nor do the mechanical or chemical properties undergo any detectable change. The composition is resistant to biodegradation and combustion, and does not creep or shrink during thermal cycling.

    Abstract: An apparatus and method for processing hazardous wastes directly from 55-gallon drums through the use of pyrolysis and steam reforming. The method is based on a pyrolyzer using heat to vaporize organics that are present in the hazardous wastes. The waste is heated in the original drums to avoid the bulk handling of alpha radionuclides and to ensure criticality control. At pyrolysis temperatures, all liquids and organics in the drums will evaporate and volatize. The resulting waste in the drums is a dry, inert, inorganic matrix with carbon char containing radioactive metals. The off-gas produced by pyrolysis mainly consists of water vapor, volatized organics, and acid gases from the decomposition of various plastics and other organics present in the waste drums. The off-gas produced by the pyrolysis is then collected and fed into an off-gas treatment system that is in fluid communication with pyrolyzer operated under oxidizing conditions.

    Abstract: The present invention provides a relatively small scale apparatus for gasifying solid fuel in which pyrolysis gas produced in a pyrolyzer by thermal-decomposition reaction of the solid fuel can be reformed to crude fuel gas. The apparatus comprises a solid fuel pyrolyzer 1 and a steam reformer 5, and thermally decomposes the solid fuel with a combustion reaction of a low oxygen density to produce the pyrolysis gas, and reforms the pyrolysis gas to produce the crude fuel gas. The pyrolyzer has an air inlet 18 positioned at a bottom part thereof and upwardly blowing combustion air into the pyrolyzer; a bed of pyrolyzer 30 located above the air inlet; and a pyrolysis gas exit positioned at an upper part of a body of the pyrolyzer and conducting the pyrolysis gas out of the pyrolyzer. The bed is made by a layered stack of many spherical heat-resistant materials 32 which form a number of narrow gaps for draft of the combustion air over the whole bed. The steam reformer has a reforming area 51 which produces the crude fuel gas by a steam reforming reaction of the pyrolysis gas, a pyrolysis gas inlet 55 which is in communication with the pyrolysis gas exit and which introduces the pyrolysis gas into the reforming area, a mixed gas inlet 54 introducing mixed gas of steam and air into the reforming area, a reformed gas effluent passage 70 for conducting reformed gas of the reforming area out of the reformer, and a permeable heat-barrier 60 positioned between the reforming area and the reformed gas effluent passage. The barrier is made by a layered stack of many spherical heat-resistant materials 62 which form a number of narrow gaps for draft of the pyrolysis gas and the mixed gas.

    Abstract: A method and portable apparatus is described for the conversion of cellulose and other blomass waste materials through a pyrolysis and partial combustion sequence in a downdraft gasifier to produce a gas which can be immediately utilized to fuel an internal combustion engine in a generator set (genset). More specifically, the heat from the combustion of part of the cellulosic or other waste input is used to pyrolyze the remainder of the input to produce a mixture of permanent fuel gases. Particulates are removed (water scrubbers, filters) from the gas mixture which can then be used directly as a major part of the fuel to operate the internal combustion engine in the genset. All movement into, through, and out of the gasifier and purification train is controlled by the vacuum associated with the intake of the internal combustion engine, thereby ensuring a steady production of electricity.
