EQUIPMENT FOR STUDYING FOULING IN ORGANIC COOLANT SYSTEMS
Technical Report
·
OSTI ID:4728214
A small-scale circulating system for screening the variables influencing fouling in organic coolants for nuclear reactors was built and tested for several months at bulk temperatures of 375 deg C, system pressures of 21 kg/ cm/sup 2/ and flows of 40 to 60 g/sec. The system requires 200 g of coolant to fill the flow circuit and can be cooled down, discharged, recharged, and reheated to operating temperature in about four hours. A fouling probe developed for use in the small loop was also used in out-reactor fouling loop and the fuel test loop in the NRX-reactor. Experience indicates that fouling mechanisms observed on large heated surfaces can be duplicated both as to deposition rate and film composition on the fouling probe. It can therefore be used as a tool for monitoring coolant fouling potential in large systems. (auth)
