Facility flow calculation by comparison of consecutive inventory lists
Inspections in installations with large numbers of articles involve considerable repetitive calculation work for the inspector. In such conditions the computer is an important working tool. It can be used during inspections for reading the inventory lists, checking sums of material weights, making the random selection of articles to be measured and managing the evaluation of measurement results. In fact, where a computerised internal accountancy system is installed, the inventory lists themselves can be produced automatically. A next step of inspection software could be the analysis of movements of nuclear material since the date of the previous inspection. Tests involving this type of analysis show a marked potential for producing a detailed model of the nuclear material flow inside a facility. The technique was created specifically for LEU fabrication plants but can be applied for bulk handling and item handling facilities alike. This paper addresses the mathematical system and the results that can be obtained. The results of a test in a large LEU facility over a material balance period are also discussed.
