AN EVALUATION OF CONDENSED POLYCYCLIC COOLANT
Condensed Polycyclic Coolant is a low-cost refinery product which was evaluated as a potertial moderator coolant for organic reactors. The radiolytic and pyrolytic decomposition rates of this candidate coolant were measured at 650 and 750 deg F; the coolant make-up rates and costs were calculated for the use of this coolant in a typical organic reactor (50 Mw(e) POPR), at several assumed operating temperatures in the range, 650-750 deg F. Comparison of make-up costs for this coolant and terphenyl coolant indicates that lower make-up costs will result from the use of Condensed Polycyclic Coolant in reactors operating with average out-of-core coolant temperatures below approximately 700 deg F. This comparison is based on differences in decomposition rates and price only; when such factors as the larger waste gas system required for Condensed Polycyclic Coolant, the greater amount of polymer disposal, etc., are considered, the make- up cost reductions resulting from the use of this coolant appear to be marginal even for reactors operating at temperatures below 700 deg F. In view of efforts to improve the plant efficiency of organic reactors by operating at higher coolant temperatures, further development work on this coolant is not warranted. (auth)
