(CNN)Here's a look at the International Atomic Energy Agency and nuclear power.
The International Atomic Energy Agency (IAEA) inspects nuclear and related facilities under safeguard agreements. Most agreements are with countries that have committed to not possessing nuclear weapons. The IAEA is the verification authority to enforce the Treaty on the Non-Proliferation of Nuclear Weapons (NPT).
The IAEA has 171 member states (as of February 5, 2019).
Yukiya Amano has been the director general of the IAEA since December 1, 2009.
There are 35 member countries on the IAEA Board of Governors, which meets five times a year.
IAEA safeguard programs monitor nuclear reactors to make sure nuclear material is not being diverted for making weapons.
