Abstract : This report covers work performed on Contract AT(30-1)-1316 between the Brown Instruments Division of the Minneapolis-Honeywell Regulator Company and the New York Operations Office of the Atomic Energy Commission. The emittance of salt-coated uranium (a eutectic mixture of lithium and potassium carbonates) was found to be about 0.86 between the temperatures of 900 deg F and 1200 deg F. The emittance of uranium oxide (U3O8) was found to be about 0.82; the emittance of the salt mixture was 0.9; and the emissivity of uranium metal between 200 deg F and 600 deg F was 0.15. A holder and housing for the Brown Miniature Radiamatic Radiation Pyrometer was developed which was flexible and could be used to advantage measuring the temperature of uranium ingots and bars during the rolling operation. A number of these units were fabricated for the Feed Materials Center at Fernald, Ohio. A calibration panel was designed and built which permitted easy calibration of the Radiamatic assemblies. This panel contained a blackbody furnace as a radiation reference source. A considerable amount of time was spent during the spring of 1952 working at the experimental rollings held at several steel mills.
