The nuclear powered steam generator started as a power plant for the first nuclear submarine, the USS Nautilus. It was designed and built by the Westinghouse Electric Company power company for the submarine; from there the company started its development and research of nuclear-powered steam generators. [ 3 ]
Using A4W data [5] with a 25% increase in thermal power, the A1B reactors are likely to produce enough steam to generate 125 megawatts (168,000 hp) of electricity, plus 350,000 shaft horsepower (260 MW) from just one reactor to power the four propeller shafts.
The Palisades Nuclear Generating Station is a moth-balled ... The Westinghouse Electric Company turbine generator can produce 725,000 ... Two steam generators were ...
The Los Angeles-class engine room also contains the steam turbines that generate electricity and drive the propeller shaft. [2] While exact specifications are classified, the S6G reactor can propel a Los Angeles -class submarine at over 15 knots (28 km/h) when surfaced and over 25 knots (46 km/h) while submerged.
The steam generator will alleviate the corrosion concerns encountered in existing designs of steam generators, while reducing component size and weight and providing greater flexibility in overall arrangement. The reactor is designed to operate for 33 years without refueling. [1] [2]
Saturated steam is channeled from each steam generator to a common header, where the steam is then sent to the main engine, electrical generators, aircraft catapult system, and various auxiliaries. There are two main propulsion turbines, one high pressure turbine and one low pressure turbine, with a moisture separator in place between the two.
The conversion to electrical energy takes place indirectly, as in conventional thermal power stations. The fission in a nuclear reactor heats the reactor coolant. The coolant may be water or gas, or even liquid metal, depending on the type of reactor. The reactor coolant then goes to a steam generator and heats water to
Dresden 1 Nuclear Flow Diagram featured a secondary steam generator for load following. The reactor featured a dual cycle, with steam coming from both the stream drum and steam generators. This made for rapid response to changes in power demand. Reactor power was regulated by actuation of the secondary admission valve by the turbine's governor.
