Summary of the Action:
The safeguards work provides direct support to the inspectorates (ESO and IAEA) and undertakes related underpinning research to prepare for future demands, including continuous improvements of safeguards activities, to adapt to political and technical changes, and to changes in verification regimes, e.g. the Additional Protocol and the interest in Np monitoring. The ITU activities include the development and assessment of instrumentation in the areas of analytical chemistry and non-destructive assay for Plutonium facilities and new fuel cycles, high performance trace analysis for the detection of clandestine nuclear activities and for identification of materials from illicit trafficking, and upgrading and of the on-site laboratories. ITU participates actively in the International Technical Working Group of the P-8 states and develops further nuclear forensics science to the benefit of both the Member States and the Candidate Countries to the European Union. Rationale Stopping the further spread of nuclear weapons is a major policy objective of the European Union.

The Euratom Safeguards Office of the European Commission (Transport and Energy DG) and the International Atomic Energy Agency (IAEA) are inspection authorities charged with the implementation of safeguards measures to control the use of nuclear materials within the European Union and world- wide, respectively. The European Commission performs safeguards inspections in the framework of chapter VII of the Euratom Treaty and in accordance with international obligations coming for example from the Non-Proliferation Treaty or international agreement with third countries (e.g. United States). The Institute is a long-standing partner of the safeguards inspectorates providing assistance and expertise particularly relevant to plutonium handling facilities, such as reprocessing and MOX fuel fabrication plants. For more than 3 decades, ITU has been providing new analytical tools to analyse and characterise.
