Evaluation of Pu sample oscillations in CESAR

Abstract

A set of 12 plutonium samples of various compositions were oscillated in CESAR in 1973. Comparisons were made to the oscillated reactivity effect of a known specimen of U-235 and boron where the detector signals were corrected against a background signal based on comparison to the motion of a control rod in the central location of critical assembly. An equivalent sample method was tested first for various samples of U-235 and boron to establish a means of correction in the detector response. Inferred plutonium reaction rates in the experiments were compared to transport theory calculations using the APOLLO code. Addition effort is needed to reconcile differences in measured and calculated results requiring both chemical analyses of the plutonium isotopes in the samples and improved cross sections for the plutonium isotopes.
