In 1956, the US Atomic Energy Commission commissioned a study on the development of heavy-water moderated natural uranium fueled power reactors with the objective of producing low-cost commercial electricity. Since these reactors do not require any enrichment, it was thought that they could be cost competitive with fossil fuel power plants. To obtain more credible data, the Heavy Water Components Test Reactor (HWCTR) was built. This film describes the Heavy Water program and the HWCTR.
