Nuclear power plants are not exactly sold on the same scale as wheat, but that they can be manufactured as an exportable commodity is well illustrated in this film. For those familiar with nuclear power generation, and even for the lay audience, this is a lucid exposition of how a nuclear power plant is put together. The film shows the machining and assembly of principal components, and the "on power" operation of the Canadian plant at Pickering, Ontario. Produced by the NFB for Atomic Energy of Canada Limited.
