  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.

 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.

 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.
