The submarine reactor comprises a core made up of fuel elements, elements for the control of reactivity, and stacks of thermionic diodes in which each stack is surrounded by an inert gas envelope and the emitter of each diode contains fissile material. The reactor core is placed within a ...
Reactors in a nuclear-powered submarine are typically fuelled with uranium. Natural uranium mined from the ground consists mainly of an isotope called uranium-238, mixed with small amounts (0.7%) of the key isotope uranium-235. For the reactor to work, theuranium fuelhas to be "enriched" t...
The nuclear power is provided by the Rolls-Royce PWR 2 pressurised water reactor. The long-life core fitted in the PWR 2 means refuelling will not be necessary for the service life of the submarine. Other main items of machinery include two Alstom turbines and a single shaft with a Rolls-...
