 Over $108 million to support the IAEA Technical Cooperation Fund (TCF), or about 25 percent of the total. Technical cooperation (TC) projects are having a positive humanitarian impact in the developing countries of Africa, Latin America, Asia, and Eastern Europe in the fields of human health, agriculture and food security, isotope hydrology and water management, the environment and climate change, and nuclear energy infrastructure and sustainability. The U.S. TCF contribution, faithfully furnished for decades, supports on a collective basis the same kinds of projects supported individually by U.S. contributions to the IAEA’s Peaceful Uses Initiative, as described below.
