An experimental investigation was conducted to develop methods and equipment for removing film-forming impurities from high-temperature irradiated organic reactor coolants. Electromagnetic and electrostatic devices as well as several filter types were found to be either ineffective or unsatisfactory for the high-temperature service required. On the other hand, fixed-bed adsorption using Attapulgus clay, at 550 to 750 deg F with superficial mass flow rates from 42 to 320 lb/hr-ft/sup 2/ of column cross section, successfully lowered the particulate concentration (as indicated by ash analysis) and reduced the fouling tendency of the coolant to acceptable levels. In addition, precoat filtration employing diatomaceous eanth filter aids proved equally successful in lowering the particulate content but was somewhat less efficient in decreasing the fouling tendency of irradiated coolant mixtures. The filtration tests were carried out with coolast flow rates between 200 and 480 lb/hr-ft/sup 2/ of filter area and at approximately 575 deg F. (auth)
