TEMPERATURE COEFFICIENT MEASUREMENTS ON A CRITICAL MOCK-UP OF EBR-I
Abstract
A rough mock-up of the EBR-I reactor was built in the ZPR-III critical assembly machine, with resistance heaters in the core and inner blanket. The variation of reactivity with core temperature was observed. Lateral expansion was measured as the core was heated. A temperature coefficient of --0.42 inhour per degree Centigrade was observed when the core alone was heated, and --0.72 inhour per degree Centigrade was observed when the core and inner blanket both were heated. Essentially all of these coefficients are attributable to volume expansion. (auth)

TEMPERATURE COEFFICIENT MEASUREMENTS OF LIGHT-WATER MODERATED HETEROGENEOUS CRITICAL ASSEMBLIES
zirconium, light water moderated assemblies in simple geometry is summarized. The assemblies consist of both uniform highly enriched media and seed-blanket slab arrays coutaining a natural uranium alloy blanket in plate form. A review is given of the typical experimeatal techniques and experimental data obtained in thae process of validating power reactor designs involving these core media. The discussion is divided into two parts; the first covering experimental techniques and the second covering certain of the data obtained. (auth) -
PRELIMINARY CRITICAL EXPERIMENTS ON A MOCK-UP OF THE LOS ALAMOS MOLTEN PLUTONIUM REACTOR
been made for fast-spectrum plutonium assemblies similar to proposed designs for the Los Alamos Molten Plutonium Reactor Experiment (LAMPRE I). The effectiveness of various systems of reactivity control has been determined. Fission rate distributions and spatial flux variations were obtained for comparison with values computed according to the S/sub n/ method. (auth)
