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 Thot 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 Thot 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.

An apparatus for improving the operational characteristics of a nuclear power electric generation plant having a steam generator that supplies main steam to a main turbine that drives an electrical generator, and a moisture separator reheater to remove moisture and superheat said main steam before directing it to a low pressure stage of the main turbine for the extraction of work, after which it is directed to a condenser where it is condensed forming a condensate, said condensate being returned to said steam generator by a feed pump, wherein the improvement comprising: (a) a high pressure mixer superheater; (b) a low pressure mixer superheater; (c) a heat recovery boiler producing a heat recovery boiler high pressure steam and a heat recovery boiler low pressure steam; (d) a chemically fueled turbine generator, producing a heated exhaust, for the heating of the heat recovery boiler high pressure steam and the heat recovery boiler low pressure steam; (i) wherein the main steam is mixed with said heat recovery boiler high pressure steam, thereby being superheated, before being directed to said main turbine; (ii) wherein the exhaust from a high pressure stage is directed to said moisture separator reheater, thereby being superheated and moisture being removed; (iii) wherein said exhaust from the moisture separator reheater is mixed with heat recovery boiler low pressure steam, thereby being superheated, before being directed to the condenser; (iv) whereby efficiency of said nuclear power electric generation plant is increased.
