OSTI ID:4136795
BS>As an extension of the Yankee and BR-3 Critical Experiments, a series of two-region critical experiments were performed at the Westinghouse Reaotor Evaluation Center from the end of 1958 through the first half of 1959. The primary purpose of these experiments was to measure the spatial distribution of neutron flux amd power production in reactor cores of simple geometric shape containing two regions of different fuel enrichments in order that a comparison could be made with analytically derived distributions for the same cores. Gold foils, U/sup 238/ foils, and fuel rods were used to obtain thermal flux, fast flux, and power production through the cores. In addition. critical size, buckling, reflector savings, and microscopic parameter measurements were made in single-region cores of 4.4% fuel in the two lattices used. (auth)
