On power refuelling [abridged version]

An outstanding factor in the efficiency of the CANDU reactor employed in Canadian nuclear power stations is that its construction allows for refuelling while the plant remains in operation, with no necessity for periodic shut-downs. Filmed at the Pickering, Ontario, station, this film clearly illustrates the processes and the advantages of this Canadian feature. Cutaway models and animated drawings are used in the demonstration.
