A feasibility study has been conducted to determine whether nuclear waste calcine and a crystalline ceramic matrix can be fabricated by hot pressing into a composite waste form with suitable leaching resistance and thermal stability. It was found that a hard, dense composite could be formed using simulated commercial fuel reprocessing waste and a matrix of ..cap alpha..-quartz with a small amount of a lead borosilicate glass added as a consolidation aid. Its density, waste loading and leaching resistance are comparable to the glasses being considered for fixation of nuclear wastes. The hot-pressed composite offers a closer approach to thermodynamic stability and improved thermal stability (in monolithic form) compared with glass waste forms. Recommendations for further optimization of the hot-pressed waste form are given.
