Experience in the implementation and testing of a nuclear material accountancy and control system at the Juelich Nuclear Research Centre

A nuclear material accounting and control system (NACS) has been developed at the Juelich Nuclear Research Centre (KFA) and has been implemented and tested with the Programme Group for Nuclear Energy and the Environment (KUU). This acts as a central coordinator in close cooperation with the Central Institute for Applied Mathematics (ZAM), the Hot Cell Facilities of KFA (HZ), the Central Department of Health Physics (ZST), and the firm Unternehmensberatung Aachen GbR. In conjunction with appropriate containment and surveillance measures and integrated measuring systems, NACS constitutes a complete nuclear safeguards system (NUSS) for research centers. This paper details the experience gained in the implementation and testing of the system
