摘要： Steam generators in power plants exchange energy from a primary medium to a secondary medium for energy extraction. Steam generators include one or more primary conduits and one or more secondary conduits. The conduits do not intermix the mediums and may thus discriminate among different fluid sources and destinations. One conduit may boil feedwater while another reheats steam for use in lower and higher-pressure turbines, respectively. Valves and other selectors divert steam and/or water into the steam generator or to other turbines or the environment for load balancing and other operational characteristics. Conduits circulate around an interior perimeter of the steam generator immersed in the primary medium and may have different cross-sections, radii, and internal structures depending on contained. A water conduit may have less flow area and a tighter coil radius. A steam conduit may include a swirler and rivulet stopper to intermix water in any steam flow.

摘要： A method of working a combined nuclear-fossil fuel cycle consisting in generating steam in a nuclear reactor, admitting fossil fuel into a regenerator operating with oxygen and effecting the gasification of the fuel therein and raising the heat potential of the steam supplied by the reactor; feeding the steam into a burner and reacting the gaseous fuel with oxygen therein and then causing the mixture of combustion products and steam to work in a turbine driving an alternator.

摘要： A solar-nuclear hybrid plant includes a nuclear energy loop, a solar energy loop, and an electrical generation loop. The three loops are closed loops. The nuclear energy loop transfers energy to the electrical generation loop through a steam generator. The solar energy loop transfers energy to either the nuclear energy loop and/or the electrical generation loop through one or more heat exchangers in the appropriate loop. This cogeneration plant has higher efficiency compared to a nuclear power plant alone.

摘要： A method and apparatus for improving the efficiency and performance a of nuclear electrical generation system that comprises the addition of steam handling equipment to an existing plant that results in a surprising increase in plant performance. More particularly, a gas turbine electrical generation system with heat recovery boiler is installed along with a high pressure and a low pressure mixer superheater. Depending upon plant characteristics, the existing moisture separator reheater (MSR) can be either augmented or done away with. The instant invention enables a reduction in T.sub.hot without a derating of the reactor unit, and improves efficiency of the plant's electrical conversion cycle. Coupled with this advantage is a possible extension of the plant's fuel cycle length due to an increased electrical conversion efficiency. The reduction in T.sub.hot further allows for a surprising extension of steam generator life. An additional advantage is the reduction in erosion/corrosion of secondary system components including turbine blades and diaphragms. The gas turbine generator used in the instant invention can also replace or augment existing peak or emergency power needs.
