Lethbridge Herald, The (Newspaper) - June 13, 1973, Lethbridge, Alberta THE LETHBRIDGE HtRAlD 33 Engineers testing reactors SASKATOON (CP) The University of Saskatchewan' division of control engineering is undertaking research aimed at improving the efficiency of nuclear power plants. Atomic Energy of Canada Ltd. at Pinawa, Man., has pro- vided a one-year initial grant of for studies of control systems and heat-exchange characteristics i n built power reactors. Canadian power reactors ara operating at Rolphton, Douglas Point and Pickering in Ontario, at Gentilly In Quebec sad in India and Pakistan. Several more plants, much larger than the existing ones, are being de- signed and are to go into opera- tion within six yean. At present, nuclear power sta- tions are not as efficient as con- ventional fossil-fuelled plants and studies, including the one in Saskatoon, are under way to im- prove the design and overcome tiiis. Like conventional plants, nu- clear power stations use heat to make steam which turns tur- and generators to product electricity. The heat is produced by tha splitting of uranium atoms inside a reactor and is transfered by. pressurized heavy water coolant to a boiler, where it turns ordinary water into steam. The fuel is relatively cheap, since one pound of natural ura- nium produces kilowatt hours of electricity compared with 1.5 kilowatt hours for a pound of coal. However, nuclear power plants now are more costly to build than conventional' stations. MUST VARY OUTPUT Existing nuclear plants pro- duce power at a constant rate. However, as the proportion of electricity from nuclear sources rises, it will be necessary to vary production in accordance with variations in demand. Prof. R. J. Fleming of the uni- versity's department of engi- neering, the project supervisor, will be studying methods of con- trolling the process so that it can respond to three variations. }OOlCO las wonderful MOTS tohelpyou Prof. G. H. Green of tbe de- partment of mechanical engi- neering will be attempting to obtain a better understanding of what on In tbe boiler, when tbe steam is produced, and what happens if the coolant, which transfers the heat from the reactor, is allowed to boil. The objective is to develop bet- ter designs for the boiler and improve efficiency. The Saskatoon researchers will be doing simulation studies end correlating these with ac- tual operating systems. Using the university's hybrid com- puter, they will produce mathe- matical models of a reactor, boiler and turbine and by vary- ing the quantities in the puter will be able to study tbe behavior of nuclear systems under different conditions. These studies win be co-ordi- nated with related work being carried on by tbe Hydro Elec- tric Power Commission of On- tario and Atomic Energy of Canada.
