From 1942 to 1945, the United States invested $20 billion (2003 dollars) into a massive nuclear research and deployment initiative. But the achievement of the first nuclear weapon test in 1945 marked the beginning, not the end, of federal involvement in nuclear technologies. President Dwight D. Eisenhower's “Atoms for Peace” address in 1953 and the 1954 Atomic Energy Act committed the United States to develop peaceful uses for nuclear technology, including commercial energy generation.
