Results of exploratory research and development on organic coolant reclamation and coolant technology to develop an economical process to reclaim decomposed terphenyl coolant are described. The solvent treatment method for reclaiming high boiler was further refined to include OMRE core IIIA high boiler and spent coolants with varying high boiler concentrations. Centrifugation was shown to be a good technique for separating the soluble and insoluble fractions. Results from electron radiolysis and reactor irradiation of reclaimed high boiler and spent coolant showed that reclaimed coolants have good radiation resistance. Hydrocracking of high boiler was demonstrated to be a feasible reclamation process. Several alkylpolyphenyls were prepared and their thermal and radiolytic stability were measured. The reaction rate constants for the thermal decomposition at 350, 427, 482, and 510 deg C were determined. Economic comparisons of recclamation processes indicated that the solvent treatment process is the most economical of the processes that are demonstrated to be technically feasible. (M.C.G.)
