Abstract
A method is described for locating and measuring nuclear material accumulations within the process vessels of a nuclear processing plant. The method was developed because if these unrecovered materials are not located and measured, the discrepancies between actual and calculated inventories remain unresolved. In this method, computerized calibration reports giving the volumes of process vessels are compared. Differences of volume that can be related to time and quantity of product throughput are used for estimating accumulations of solid material. This feature enables the manager of a processing plant to rapidly determine the feasibility of solid-material recovery. Proposed refinements, to this method, include the utilization of the computer to provide current data from which a plant manager can predict the accumulation of material.
