THE ROLE OF STEAM GENERATORS AT NUCLEAR POWER STATIONS USING WATER COOLANT

The factors involved in the use of steam generators in boiling-water reactors are discussed, e.g., water purity, condenser leakage, steam-generator position, and reactor protection. Both direct and indirect cycles are considered. A combination of direct and indirect cycles is possible in high the reactor steam drives a high-pressure turbine and then passes to a ateam generator located ahead of the low-pressure turbine. In this way, the plant output can be increased without increasing the steam and corrosionproduct contents in the core. Complete elimination of steam generators from nuclear power stations will be possible only if reliable and cheap filters are made for high-temperature and high-pressure use. (D.L.C.)
