Welcome to the IAEA Coordination Group for Uranium Legacy Sites - CGULS

The IAEA's Coordination Group for Uranium Legacy Sites (CGULS) promotes cooperation among Member States with uranium legacy sites and national and international organizations that support work remediate the sites.

Through CGULS, the IAEA supports a network of national and international organizations and institutions concerned with the remediation and the safe management of residues at these uranium legacy sites. Most of the sites are located in Central Asia with some located in other Member States.

CGULS facilitates information exchange, coordination and optimization of resources in work to reduce risks to people and the environment.

The IAEA assists Member States in the development of regulatory frameworks, and in capacity building activities for regulatory bodies and operators of the uranium legacy sites. 

The CGULS project facilitates the application of IAEA safety standards and international good practices in remediation projects conducted in Kazakhstan, the Kyrgyz Republic, Tajikistan, Uzbekistan and Ukraine.

CGULS comprises the IAEA, the European Commission, the Commonwealth of Independent States and the European Bank for Reconstruction and Development. Germany, Norway, France and Belgium as well as other Member States support the Group.
