Temperature Dependence of Thermal Diffusion Length for Plutonium-Beryllium Neutrons in Borated Water.
Abstract
The temperature dependence of diffusion length for PU-BE neutrons in distilled water poisoned with boric acid was studied using concentrations of 1.0, 8.0, 16.0, and 30.0 grams per liter. Runs at each concentration were made at temperatures of 95, 131, and 167F. The trend of temperature dependence was clearly established. A theoretical temperature dependence of kappa squared, where kappa=1/L is proposed using a Maxwellian distribution. (Author)
