The expenses resulting from the functioning of the individual components of the power station itself play an important role in the cost of the reactor- generated electricity. The largest portion is absorbed by the operating cost of circulating pumps, turbines, feed pumps and the steam generator. In the case of gas-cooled, natural-uranium fueled reactors these factors make it more economical to build high power level reactors either by increasing the dimensions of the reactor or by making use of higher fuel temperatures. In the latter case a higher utilization factor is obtained but the refractory properties of the materials used must be improved. An alternate method consists in reducing the energy expenditure of circulating the coolant and in the increase of the flow rate through the reactor. this can be achieved by providing supplementary cooling of the gas before it returns to the blower and by forming a temperature profile of the flow through the reactor. This latter method however results in an uneven burnup of the fuel elements which may cause increased thermal stresses in the central channels. (TTT)
