The European Commission and the International Atomic Energy Agency (IAEA) celebrate 30 years of cooperation in the safeguarding of nuclear materials and facilities. This anniversary is marked by an event at the IAEA Headquarters in Vienna. The Joint Research Centre (JRC) of the European Commission has provided scientific and technical support to the work of IAEA since 1981, with over 100 scientists and technicians working on more than 25 projects. The anniversary is also an opportunity for both parties to plan their future joint activities.
