Abstract
The paper outlines the brief history of a Working Group composed of nuclear fuel plant operators, safeguards research workers and safeguards inspectors who are examining facility orientated problems of nuclear materials control and verification activities. The working programme is reviewed together with some examples of various problems and the way the group is collaborating to develop solutions by pooling resources and effort. Work in European low enriched uranium fabrication plants from \\n?Q to finished fuel is discussed in connection with measurement practices, real time accounting, error propogation and analysis, verification and surveillance. Emphasis is placed on the practical aspects related to plant operations.
