Results of Recent Analyses of Borax Ii Transient Experiments

Abstract

Heat transfer information relating to the shutdown mechanism of the Borax II reactor is discussed. Pertinent quantities are presented as a fimction of time for a typical power transient. A proportionality is established between the transient steam pressure pulse and-kex-'^'h.& heat transfer from fuel plate to water is divided into conduction and boiling phases. Conduction and boiling are shown to exhibit equilibrium behavior except during the transient steam pressure pulse. Because of the incompleteness of the data a definitive description of the phenomena during this pulse is not possible.

Random noise analysis in the Iowa State University UTR-10 reactor

“…The transient behavior of the reactor after a step or ramp addition of reactivity has been studied (17,28). This technique yields information on the self-regulating capabilities of the reactor and the shut-down mechanisms but other information is limited.…”
