INMACS: Commissioning, Management and Operating Experience of an On-Line Fissile Material Inventory and Criticality Control System

This paper describes the commissioning and daily management of INMACS, the Integrated Nuclear Material Accounting and Control System used in the Recycle Fuel Development Laboratory at Chalk River. Operating experience to date has been excellent, and no basic changes have been necessary either to the operating procedure or to the computer programs which check and record the various processing operations, material transfers and bookkeeping adjustments. INMACS has been accepted enthusiastically by the laboratory staff who appreciate the efficiency with which pertinent inventory data can be recorded and retrieved.
