	United States Naval reactor
		United States Naval reactors are given three-character designations consisting of a letter representing the ship type the reactor is designed for, a consecutive generation number, and a letter indicating the reactor's designer.
		After the Skate-class vessels, reactor development proceeded and in the USA a single series of standardised designs was built by both Westinghouse and General Electric, one reactor powering each vessel.
		A marine reactor was used to supply power (1.5 MWe) to a US Antarctic base for ten years to 1972, testing the feasibility of such air-portable units for remote locations.

	S5W reactor - Wikipedia, the free encyclopedia
		The S5W reactor is a naval reactor used by the United States Navy to provide electricity generation and propulsion on warships.
		This pressurized water reactor's simplicity, over design, and redundancy was intended for ease of operation and tolerance of battle damage.
		Later-model S5W reactor plants were often refueled with a S3G core-3; that is, the third version of the S3G core.

		The prototype was fitted with a small reactor generating a power of 20 MWt and 2 500 shp.[619] There were considerable technical problems with this submarine, and the prototype was the only one built.
		The operation of the DS/MP reactor in Dounreay and experiences with the S5W reactor led to the development of the first generation of British pressurised water naval reactors, the PWR-1, with a thermal power of 70 MWt, and 15000 shp.
		This reactor was used for the first time on board a vessel of the Vanguard class, which is slated to replace the Resolution class of submarines.

	S7G reactor
		The S7G was a unique design of United States Naval reactor that did not use control rods.
		It consisted of a unique reactor core installed in a modified S5W reactor[?] plant.
		Instead of moveable hafnium-based control rods, which are used in all other United States Navy reactors, reactivity in the S7G core was controlled by stationary hafnium-clad tubes partially filled with water.

		In addition, until the commissioning of the Ohio Class Ballistic Missile Submarines, the Triton was the longest submarine ever built by the U.S. Navy.
		This reactor became the U.S. Navy’s standard until the Los Angeles class joined the fleet in the mid-1970’s.
		Hull streamlining, reduction in sail dimensions by approximately 50 percent, quieting of the S5W reactor plant and an increase in test depth all lead to a dramatic advance in submarine operational capabilities and stealth.

		A version of the standard S5W reactor in which the S5W is coupled with a scaled-up (by a factor of six) version of the Tullibee’s turbo-electric drive.
		This family of reactors was not regarded as being efficient since reactor shielding weight does not decline in proportion to reduced power output.
		Operational Reactor Development work was to include the design, development, test and evaluation of reactor refueling equipment and methods to support the initial SSBN-726 Ohio class refueling, the defueling of power units aboard CVN-65 USS Enterprise and the continued CVN-68 Nimitz class refueling.

	S3G reactor - Wikipedia, the free encyclopedia
		The S3G reactor is a naval reactor used by the United States Navy to provide electricity generation and propulsion on warships.
		It was the prototype for the two reactors used aboard the USS Triton (SSRN-586).
		Many S5W reactor plants were refueled with the skew-divergent S3G core 3.

		USS Skipjack was the lead ship of the first class of nuclear-powered submarines built with the Albacore hull design, and also unique in that it was the first nuclear submarine with a single shaft.
		Placement of the bow planes on the sail greatly reduced flow noise at the bow-mounted sonar.

	French Nuclear Propulsion - Archived 5/2001
		The reactors are designed for the production of steam, which in turn is used to generate propulsion power and electricity and to operate the soft-water plant onboard.
		The reactor, later known as K-15, was fundamentally very similar to the CAS-48 in the Rubis class but took advantage of the more generous proportions of the hull to allow rafting of the main machinery; provide additional steam cooling loops; and increase the number of passes made by the primary reactor cooling fluid to three.
		The first reactor may in fact have already been delivered to the builder, or could be delivered momentarily, since the first boat is expected to be launched around 2008 (for starting of the sea trials).

		With their constant pump operation they are noisier than a conventionally powered submarine - the Upholders when SNORKELING were as noisy as a SSN in its normal operation - this they only had to do for 30-60 minutes a day - the rest of the time they were much quieter and extremely difficult to detect.
		It would just require more capable motors, larger batteries, a dedicated method of charging them from the reactors gas turbines, and a reactor that can be shutdown and reactivated with the minimum of fuss and time.
		In addition the NARWHAL is reported to have a natural circulation reactor and a direct-drive turbine that didn't require reduction gears.

		All 129 men aboard at this point were intently watching the hull, all pipes and fittings, and every gauge on the ship for signs of malfunction as the ship slowly descended to depths never achieved after the overhaul.
		A submarine should be able to surface without relying on its reactor because it is also well-known that they are susceptible to shutting down.
		Test depth is when a reactor “scram” is most likely due to the high risk of flooding.

		On later investigation, a crack, also described as a split, was found at a critical junction of the pipes in the pressurized water reactor's cooling system, where a welding fault was discovered.
		Apparently it was not just that the reactor was about to seize up, or that the reactor was at the point of failure, the reactor was, in fact, seriously damaged.
		It is quite possible that the time element to surface and to perform the casualty procedure was of such duration that a portion of the reactor core uncovered while the reactor was still at power.

		The Westinghouse Electric Corporation's S5W nuclear reactor was the standard reactor for ships of the United States Navy from its first use in 1959 in the USS Skipjack to the introduction of the Los Angeles class submariness in the mid-1970s One such plant was also used in Britain's first nuclear-powered submarine HMS Dreadnought (S101).
		It should be noted that for security reasons, accesses to the reactor spaces on any submarines or surface vessels is restricted to authorized personnel only.
		Two S5W reactor plants remain in service, the MTS 626 (ex-USS Daniel Webster) and the MTS 635 (ex-USS Sam Rayburn).

		The Polaris submarine's reactor is of a similar design to that on HMS Warspite, which the UK Ministry of Defense has admitted has faults with its primary coolant system.
		The design of the faulty reactor used in the HMS Warspite was developed from a reactor bought complete from the US and installed in the first UK nuclear powered submarine HMS Dreadnought in 1962.
		This S5W reactor was designed by Westinghouse and installed in the early US Navy Skipjack class nuclear powered submarines and others until it was replaced in 1979 by the Los Angeles class submarine.
