1,210,686. Nuclear power plants. GENERAL ELECTRIC CO. 19 Dec., 1967 [11 Jan., 1967]. No. 57644/67. Heading G6C. In a steam cooled, fast nuclear reactor, superheated steam from the reactor is supplied to a turbine after the removal of radioactive contamination. Superheated steam passes from the reactor 10 through line 36 to the steam generator 14 where desuperheating of the steam and evaporation of water 40 occurs. Saturated steam is pumped from 14 by circulator 16 to the reactor coolant inlet. A minor fraction of the steam from 14 is urged through line 64, is superheated in the heat excharger 12 by the reactor coolant, and is passed to the turbine 20 through line 54. The contamination from the reactor core is retained in the water 40 and is removed by filtration and ion-excharge. The annulus 150, Fig. 2, is filled with water and steel rods 152 to form a shield round the core 28, the water flow rate being controlled to prevent boiling. The core has a central fuel region surrounded by a reflector and each vertical fuel rod consists of an upper void region, upper and lower reflectors and a central fuel zone. |
