Abstract
This document briefly describes the method used to estimate a screening value for the Total Failure Probability (F~T~) of human error events that are identified in the fault trees which describe potential liquid UF~6~ release accidents at two U.S. Gaseous Diffusion Plants. A discussion is provided of the assumptions, limitations, and overall logic of the F~T~ assignment method, and a description is presented of how the method is employed. The description herein, and more completely in Burns and Turner [1], presents the screening technique* used to quantify human errors in the accident analysis portion of the Gaseous Diffusion Plant Safety Analysis Report Upgrade Program.
