US Nominations for IAEA Meetings

As the center of international nuclear collaboration, the International Atomic Energy Agency (IAEA) organizes and hosts numerous topical and technical meetings every year, inviting experts from around the world to participate and contribute.

The purpose of these meetings is to work out a set of recommendations and advice, or provide analyses of aspects of individual projects or specific programmatic areas.

IAEA Programs at Argonne National Laboratory is responsible for processing nominations and invitations of US citizens to attend IAEA non-safeguards technical and consultancy meetings, workshops, training courses, expert missions, and international conferences. This includes US citizens living stateside and abroad, as well as those with dual citizenship. It is US Government protocol to prepare a country clearance cable for all US Federal and USG contracted personnel attending IAEA events. In addition to USG employees, the Office also tracks US citizens from private sectors who are processed to completion. The Office processes more than 900 invitations and nearly 2000 nominees each year.

USG experts who have received an invitation or nomination from the IAEA will be contacted by IAEA Programs to complete paperwork to achieve this clearance. No action is required by the Office for US experts from private sectors. Once the Office has completed the nomination process, each private citizen will be notified via email in this regard.
