AUTOMATED GAMMA SCANNING SYSTEM FOR ON-LINE INSPECTION OF INDUSTRIAL PROCESS COLUMNS

摘要

Gamma scanning results are in agreement with the tower internals. Scan results indicate, that the column is healthy and operating satisfactorily. Prototype automated gamma scanning system has been successfully demonstrated from the control room, using around 500 m of cable length. This establishes the system's worthiness. It is planned to test the usefulness of this system in a few other industries, before making a commercial model. Availability of this system will meet the long felt need, to reduce the overall inspection time, for gamma scanning of process columns.
