Serial Reports on Start-Up Experiments. No. 1. the Hot Rod Experiment,
Abstract
The purpose of this new series of reports is to present in roughly finished form the results of the various start-up experiments on the BNL reactor as soon as the analysis of the experimental data is completed. The purpose of the experiment was to determine the metal temperature coefficient of the reactor. Computations by the theoretical group indicated that if several cartridges were heated to a few hundred degrees Centigrade and placed in channels near the reactor center, a change of a few inhours of reactivity would result during the cooling period. The experimental technique used was the following: with the hot cartridges in place, the control rods were adjusted to produce a slightly falling reactor period at a negligible power level. As the cartridge temperatures decayed, the reactivity of the reactor increased until a positive period was observed. The #9 control rod was then adjusted to bring the reactor slightly below critical. This procedure was repeated several times during the experiment.
