Time series analysis of reactor thermocouple data. [LMFBR]

Description: Time-series analysis techniques are applied to nuclear reactor thermocouple data to investigate coolant temperatures measured within the fueled test assembly. The coolant temperature distribution within a fuel assembly affects the length of time a fuel assembly may be operated in a power reactor and, therefore, is an important economic consideration in the design of reactor fuel systems. Frequency-domain signal conditioning techniques were used to reveal the smoothly varying thermocouple signal… more

Investigation of Sulfur-Tolerant Catalysts for Selective Synthesis of Hydrocarbon Liquids From Coal-Derived Gases. Quarterly Technical Progress Report, March 19-June 18, 1980

Description: A 15% Fe-3% K/sub 2/O on SiO/sub 2/ catalyst, a 15% Co-3% K/sub 2/O on SiO catalyst and a 15% CoB/SiO/sub 2/ catalyst were prepared. H/sub 2/ and CO chemisorption uptakes were measured for the catalysts prepared to date. It was noted that calcining the iron catalysts in air before reduction in flowing H/sub 2/ aided in increasing metal dispersion. Liquid and wax traps for use in the reactor system were completed as were plans for chromatographic product analysis.
