An investigation was conducted to determine the magnitude of error in surface temperature measurements of the OMRE fuel plate, using a chromel-alumel thermocouple assembly. Apparatus for the purpose of this calibration was fabricated and tested. Performance tests on control rods are described. Three tests on the time interval between scram signal and downward movement of the poison elements were run. Shielding studies on the fuel handling coffin were performed. Experimental forced, convection heat transfer and fouling runs with unirradiated Santowax 0-M (2 parts ortho-, 1 part meta-terphenyl) were completed. The carbon and hydrogen content of irradiated coolants was determined in order to measure the effect of coolant decomposition on moderating ability. The effects of radiation on the density of ortho-, meta-terphenyl and Santowax R were determined over the temperature range 300 to 850 deg F, while the density of irradiated diphenyl was determined from 300 deg F to its normal boiling point. The viscosity of irradiated ortho-, meta-terphenyl was determined over the temperature range 300 to 850 deg . The melting point of irradiated diphenyl was determined. Distillation curves for the irradiated coolants are given. Results from acceptance tests on ortho-, meth-terphenyl are presented. (For preceding period see NAA-SR-2150.)
