The S1W reactor was the first prototype naval reactor used by the United States Navy to prove that the technology could be used for electricity generation and propulsion on submarines. The designation of "S1W" stands for S = Submarine platform; 1 = First generation core designed by the contractor; W = Westinghouse was the contracted designer
For a long time, the Mark 37 was a primary U.S. submarine-launched ASW torpedo. It was replaced by the Mark 48 starting in 1972. The remaining inventory was then rebuilt and sold to several countries, including Israel, as the NT-37C after the vacuum tube guidance systems were replaced by solid-state electronics and the electric propulsion was ...
The first nuclear-powered vessel, the submarine USS Nautilus, put to sea in 1955. USS Nautilus marked the beginning of the transition of submarines from relatively slow and short-ranged conventional submarines to ones capable of sustaining 20–25 knots (37–46 km/h; 23–29 mph) submerged for weeks on end.
The S5W was the standard reactor for submarines of the United States Navy from its first use in 1959 on USS Skipjack until the introduction of the Los Angeles-class submarines with S6G reactor in the mid-1970s. One S5W plant was also used in the United Kingdom on the Royal Navy's first nuclear-powered submarine HMS Dreadnought. [1]
Rolls-Royce Marine Power Operations at Derby was the centre for design and manufacture of the UK's submarine reactors, and remains so today. The Ministry of Defence's Vulcan Naval Reactor Test Establishment (NRTE), at Dounreay, tested each reactor core design prior to its installation in nuclear submarines. Submarines. Prototype
This nuclear reactor was constructed by General Electric as a prototype for the USS Seawolf submarine. It was a liquid metal cooled reactor using pure sodium to cool the core instead of water, because the higher temperature of liquid sodium (compared to pressurized water) enabled the production of more superheated steam in the steam generators.
The first prototype, a 3-meter (10-feet) long submarine called EMS-1, was designed and tested in 1966 by Stewart Way, a professor of mechanical engineering at the University of California, Santa Barbara. Way, on leave from his job at Westinghouse Electric, assigned his senior year undergraduate students to build the operational unit. This MHD ...
The 38 8-1/8 was reverse-engineered in the USSR and used as a primary engine for railroad locomotives. The first Soviet mass-produced diesel locomotive, TE3, was powered by a 1470 kW (2000 hp) 2D100 engine, direct descendant of the marine 38 8-1/8 engine. The TE3 was produced in high numbers (up to 7600 units), and proved to be a reliable ...
