POTS Cascade Transient Code and the Calculation of the Times Required to Get Production U-235 Gradients at Oak Ridge and Paducah

摘要

This report describes the POTS Gaseous Diffusion Transient Analysis Code and how it was used to calculate the times that would be required to get production uranium-235 (U-235) gradients in the cascades at the Oak Ridge and Paducah Gaseous Diffusion Plants if the cascades were restarted after an extended shutdown. Version 3.0 of the POTS code, the method used to calculate the times, and plots showing how the U-235 gradients would change after the cascades were restarted are presented. (ERA citation 13:028884)
