An evaluation panel was organized to aid in the selection of an appropriate solid form for the high level wastes generated by chemical processing of fuels at the Idaho Chemical Processing Plant. This report is a summary of the panel's findings. The panel agrees that the best choice is borosilicate glass because its performance is acceptable, it represents a well developed process and hence it can be implemented expeditiously. In-can melt appears to be the best process at this time, however, development may result in the continuous melt process proving to be better. Stabilized calcine in a matrix, based on the data presently available, may be acceptable. The ratings are based on performance predicted from scanty experimental evidence. If these preliminary observations stand up, the performance of stabilized calcine in fuetap should be satisfactory and the more attractive processing characteristics of this form would prevail. The glass-crystalline and the other crystalline forms have not been developed to a point demonstrating superior performances that would justify their replacing borosilicate glass. System performance improvements great enough to justify more R and D, and probable higher cost, must be also shown. An objective basis to conclude that increased leach resistance will decrease risk to humans does not now exist.
