Following conversion of the GHARR-1 research reactor, completed in July 2017, the United States in cooperation with Ghana, China, and the IAEA removed all remaining HEU from Ghana. The transfer involved approximately one kilogram of HEU.

With the removal of HEU from Ghana, 33 countries plus Taiwan are now HEU-free (NNSA counts 32 countries plus Taiwan, but its count does not include Iraq).
