1,171,856. Nuclear power plant. ALLM€NNA SVENSKA ELEKTRISKA A.B. 30 March, 1967 [31 March, 1966], No. 14529/67. Heading G6C. In a boiling water reactor, circulation of the water through the core is effected by jet pumps through which water is urged by pumps external to the pressure vessel. Two external flow paths are provided, one through a turbine and one, which includes the jet pumps, independently controllable to permit adjustment of the water flow through the reactor. The latter effects regulation of the reactor temperature and thus also of its power output. Light or heavy water may be employed and in the latter case a large range of control is provided by the change in the moderating effect of the water with temperature. |
