1,247,228. Reactors. SIEMENS A.G. 17 April, 1969 [17 April, 1968], No. 19772/69. Heading G6C. The reactor core, 2, is cooled by a downward flow of steam. At the box, 13, oart of the super heated steam is discharged from the pressure vessel 1 at 14 and part flows through the conduits 16 to the nozzles, 17, within the water, 3, where fresh saturated steam is formed. The pumps 7, 8 urge the steam, through conduits 10, 11 to the box 12 for further circulation downwards through the core. In further embodiments, steam circulation is effected by steam nozzles operated by high-pressure steam and the box 13 may comprise an inner section and a concentric outer one where the heat distribution is less than at the central core region. |
