Nuclear Energy Agency purposes."" NEA currently consists of 33 countries from Europe, North America and the Asia-Pacific region. In 2017 Argentina and Romania accessioned to NEA as its most recent members. Together they account for approximately 85% of the world’s installed nuclear capacity. Nuclear power accounts for almost a quarter of the electricity produced in NEA Member countries. The NEA works closely with the International Atomic Energy Agency (IAEA) in Vienna and with the European Commission in Brussels. Within the OECD, there is close co-ordination with the International Energy Agency and the Environment Directorate, as well as contacts with other directorates, as appropriate.
Atomic Energy Act of 1946 control of fissile materials, the ownership of patents and the operation of production facilities placed a number of legal roadblocks in the way of private nuclear power stations. This was at odds with the Eisenhower administration's Atoms for Peace program, and resulted in pressure on federal officials to develop a civilian nuclear power industry that could help justify the government's considerable expenditures on the nuclear weapons program. In 1953 the Atomic Energy Commission presented a set of draft amendments to the Joint Committee on Atomic Energy for consideration. After some debate, this resulted in the Atomic Energy Act of 1954.
