摘要： Jet pumps and a feed water sparger are disposed in a reactor pressure vessel incorporating a core. A first feed water pipe supplies a portion of feed water to the jet pumps as their driving water. A second feed water pipe connected to the first feed water pipe supplies the remaining portion of the feed water to the feed water sparger. A first feed water heater is disposed in the first feed water pipe downstream of a connecting point of the first feed water pipe and the second feed water pipe. An amount of extracted steam introduced into the first feed water heater is controlled on the basis of a difference in the temperature between feed water flowing through the first feed water pipe and the feed water flowing through the second feed water pipe.

摘要： Disclosed is a nuclear power plant comprising a closed gas-cooling circuit and a plurality of identical, parallel-connected thermodynamic circuits (loops) symmetrically installed. Each of these loops constitutes a turbine assembly comprising a turbine and a compressor as well as devices for the internal and external heat exchange and is coupled with a nuclear reactor. The reactor is installed in the center of a cavern located in a vessel made of reinforced concrete, while the components comprising the circuit and the conduits connecting the various components are installed in cavities inside the reinforced concrete vessel. The turbine assemblies are located in horizontal shafts in the lower region of the vessel, and vertical shafts are provided for the gas transport pipes, which are arranged coaxially therein. These shafts and also pods for the heat exchange equipment are arranged symmetrically about the vessel axis.

摘要： A heat exchanger arrangement wherein a plurality of cylindrical modular heat exchanger units are stacked upright in side-by-side relation within an enclosure and can be transferred into and out of the enclosure, one at a time, through a passage in the floor thereof. To transfer any given heat exchanger unit out of the enclosure, the unit is detached from its base, hoisted by an overhead travelling crane into a position overlying the floor passage and then lowered vertically into a basculating bridge underneath the floor. The bridge is then tilted into a horizontal attitude to discharge the unit. Transfer of a unit into the enclosure is accomplished by following the foregoing procedure in reverse order.
