Control of radiation exposures at CANDU nuclear power stations

Measures now being applied to Candu type nuclear power stations to ensure that the radiation dose to workers at current and future stations is as low as possible are considered. Improvements already made in coolant chemistry, coolant purification, decontamination, and other areas, are discussed. Modelling studies of activity transport and improvements resulting from taking man-rem into consideration at the design stage of a station, are described. Also under investigation are detailed cost-benefit appraisals, studies on tritium control, and also fission product transport and removal. (U.K.)
