Belarusian software for nuclear material accounting at the level of the regulatory body

A review of the information system for nuclear material accounting and control at the level of the Belarusian regulatory body in the field of nuclear and radiation safety is presented. This system is developed in accordance with International Atomic Energy Agency (IAEA) requirements depicted in Code 10 of the State subsidiary arrangements. The system provides automatic generation of the following accounting reports: physical inventory listing, inventory change report, material balance report, and textual report for each material balance area as well as the corresponding General Ledger. It provides all necessary calculations and pre-calculations, based on input data, to produce accurate accounting reports. The system implements the import/export of data to/from the system using Code 10 (labelled and fixed formats), as well as making adjustments to accounting documents in accordance with IAEA rules. There are two possibilities of nuclear material accounting in the system. The first consists of importing into the system of all reporting documents from the material balance areas of facilities and the subsequent possibility of checking the received data using an independent recalculation tool in the system. The second one includes the registration of all necessary information on nuclear material batches at locations outside facilities and their movement in the material balance area and then automatic generation of all required reports and General Ledger.
