The Thermal Oxide Reprocessing Plant, THORP, is one of Europe's largest and most complex engineering projects. It will provide an essential link in the civil nuclear fuel cycle, helping to maximise the energy yield from uranium. It also presents an important challenge from the point of view of nuclear material accountancy and safeguards, by virtue of the large quantities of plutonium that will be recovered for recycling. Many new safeguards implementation features have been developed in the areas of authentication, signal branching, in-line NDA, monitoring/logging systems, anomaly resolution, on-site independent DA, construction and commissioning verification and data handling. These will ensure that the plant, from irradiated fuel storage through reprocessing, finishing and product storage, is subject to efficient and effective Euratom multinational safeguards. The main lessons which can be learned from the project are discussed.
