The 28-minute documentary film on the Experimental Breeder Reactor-I (EBR-I) tells the story of the first nuclear reactor built by the Atomic Energy Commission. With first-hand accounts from scientists and engineers, the film explores the challenges of creating the world's first reactor to produce usable quantites of electricity and "breed" more fuel than it consumed. Completed in 1951, the EBR-I paved the way for future generations of "peaceful" reactors and was named a National Historic Landmark in 1966 by President Johnson.
