WebbIn 1950, the nuclear power plant project was converted to a Naval Nuclear Propulsion project. Several years later Knolls work joined that of Bettis Atomic Power Laboratory , the Argonne National Laboratory , and others in birthing the world's first nuclear-powered submarine , the USS Nautilus on January 21, 1954.

WebbIt also allows the reactor to be more compact. The PWR uses enriched uranium fuel with a slightly higher enrichment level than in a BWR. This is responsible for a higher power density within the reactor core. As with the BWR, the fuel is introduced into the core in the form of uranium oxide pellets. A typical PWR will contain 100 tonnes of uranium. Most naval nuclear reactors are of the pressurized water type, with the exception of a few attempts at using liquid sodium-cooled reactors. A primary water circuit transfers heat generated from nuclear fission in the fuel to a steam generator; this water is kept under pressure so it does not boil. This circuit operates at a temperature of around 250 to 300 °C (482 to 572 °F). Any radioac…
