For gas-cooled reactors two thermodynamic cycles working according to different principles are used, namely the direct single loop and the two circuit system with indirect heat addition to the working medium. The direct closed cycle gas turbine circulates the cooling medium through the heat source without additional losses and without the need for external pumping power. For the two loop cycle various possibilities for the circuit exist. Some of these cycles with their losses are compared with the single loop giving results as follows: The pumping power needed for a primary cycle is found to be in the range of 8 to 20% of the usefnl output. With a turbine in the primary cycle driving the circulation-compressor losses of approximately 10% have to be expected, mainly due to the fact that the maximum temperature in the working cycle is lower than the reactor outlet corresponding to the turbine expansion. A number of other diagrams allowing the working cycle to operate close to reactor outlet temperature are discussed. The systems incorporating heat exchangers have smaller losses of approximately 5%. Some of the new schemes are only applicable wlth steam generating plants. (auth)
