Book excerpt: The complete results of the Army Package Power Reactor Zero Power Experiments performed on the APPR1 core at the Alco Criticality Facility are given. The fully loaded cold clean core, containing 22 480 1 grams of U/sup 235/, has an excess K of approximately 16%. The temperature coefficient at 170 deg F is approximately --0.67 x 10/sup -4/ DELTA K/ deg F. The presence of fine structure in neutron flux measurements and control rod calibrations is evident and further study of these effects from an academic point of view seems justified. Peak to average flux in the core is as much as 4 to 1 in the tip of the center control rod fuel element. However, flux suppressors placed in the water hole in this region are effective in reducing this value to approximately 3 to 1. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: Experiments were performed using APPR-1 fuel elements in cores having various diameters, metal to water ratios and boron-10 distributions. The presence of steel in the reflector made a noticeable increase in the core reactivity under certain circumstances. A relatively simple technique was used to determine the gamma dose rates through shielding materials yielding values in reasonable agreement with theory. Many gross and fine structure tranverses were made with gold, indium and uranium foils including traverses in cores with uniform and non-uniform poison distributions and various control rod configurations. Temperature coefficients of reactivity were nearly identical for various cores from 65 to 130 deg F. (auth).
