The Role of NMAC Audits in Euratom Safeguards - Development of an audit framework

The use of audits of nuclear facility operators' nuclear material accountancy and control (NMAC) systems has evolved since the idea was launched some years ago. The European Commission has developed a framework that enables the use of NMAC system audits as an effective and efficient tool in nuclear safeguards. The framework includes elements like audit definition and concept, a procedure, audit criteria and the approach for using audits. The main elements of this framework have been built upon ESARDA working group recommendations and were widely consulted with Member States and nuclear operators. The framework and experience from its application are presented.
