Patent number: 6812174Abstract: The invention relates to methods of vitrifying waste and for lowering the melting point of glass forming systems by including lithia formers in the glass forming composition in significant amounts, typically from about 0.16 wt % to about 11 wt %, based on the total glass forming oxides. The lithia is typically included as a replacement for alkali oxide glass formers that would normally be present in a particular glass forming system. Replacement can occur on a mole percent or weight percent basis, and typically results in a composition wherein lithia forms about 10 wt % to about 100 wt % of the alkali oxide glass formers present in the composition. The present invention also relates to the high lithia glass compositions formed by these methods.Type: GrantFiled: May 19, 2003Date of Patent: November 2, 2004Assignee: Westinghouse Savannah River CompanyInventors: Carol M. Jantzen, John B. Pickett, Connie A. Cicero-Herman, James C. Marra

Patent number: 6329563Abstract: The present invention relates to vitrification of ion exchange resins that have become loaded with hazardous or radioactive wastes, in a way that produces a homogenous and durable waste form and reduces the disposal volume of the resin. The methods of the present invention involve directly adding borosilicate glass formers and an oxidizer to the ion exchange resin and heating the mixture at sufficient temperature to produce homogeneous glass.Type: GrantFiled: July 16, 1999Date of Patent: December 11, 2001Assignee: Westinghouse Savannah River CompanyInventors: Connie A. Cicero-Herman, Rhonda Jackson Workman

Patent number: 6320091Abstract: Disclosed is a process for making a ceramic composition for the immobilization of actinides, particularly uranium and plutonium. The ceramic is a titanate material comprising pyrochlore, brannerite and rutile. The process comprises oxidizing the actinides, milling the oxides to a powder, blending them with ceramic precursors, cold pressing the blend and sintering the pressed material.Type: GrantFiled: June 22, 1999Date of Patent: November 20, 2001Assignee: The United States of America as represented by the United States Department of EnergyInventors: Bartley B.

Patent number: 5960368Abstract: The present invention is directed to a process for reducing the volume of low level radioactive and mixed waste to enable the waste to be more economically stored in a suitable repository, and for placing the waste into a form suitable for permanent disposal. The invention involves a process for preparing radioactive, hazardous, or mixed waste for storage by contacting the waste starting material containing at least one organic carbon-containing compound and at least one radioactive or hazardous waste component with nitric acid and phosphoric acid simultaneously at a contacting temperature in the range of about 140.degree. C. to about 210 .degree. C.Type: GrantFiled: May 22, 1997Date of Patent: September 28, 1999Assignee: Westinghouse Savannah River CompanyInventors: Robert A. Pierce, James R. Smith, William G.
