ICEBERG : An Informatic Platform Processing Nuclear Material Accounting Data
for French Non Proliferation Commitments

A proper accounting system is among the pillars that structure the Euratom safeguards implementation. Accounting declarations from nuclear operators are also crucial for the preparation of the many reports required under France's nuclear non-proliferation commitments, to the European Commission, AIEA safeguards agreement or national regulation. Among its missions, IRSN (Institute for Radioprotection and Nuclear Safety), as technical support for CTE (Euratom Technical Committee, the French authorities‘ representative for Euratom) is responsible for managing and processing accounting data from operators for national and international declarations. In order to optimize the process of preparing these declarations and ensure long-term data storage, IRSN is currently developing a new informatic platform called ICEBERG (Intégration de la Comptabilité Euratom en Base pour l’Etablissement des Rapports sur les Garanties). Partially funded by the French recovery plan, ICEBERG firstly consists of a module which integrates accounting declarations, both from national and international regulations, with syntactic and semantic controls. ICEBERG will also build numerous reports by aggregating data from both regulations, with respect to each report formalism and requirements. In order to simplify the analysis, the tool will automatically highlight discrepancies and major changes in each final report. Besides, a request module will allow the user to extract information from the databases. Overall, ICEBERG contributes to the reliability and durability of accounting declarations from French nuclear operators. The tool also allows for more efficient and secure reporting. This paper presents the framework and objectives of the new ICEBERG tool. Then, its structure and the reflection around the management rules will be discussed.
