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, the uranium fuel has to be “enriched” to contain the desired proportion of uranium-235.

The neutron moderator plays a crucial role in nuclear reactors by participating in the management of nuclear fission reactions. Its main function lies in the task of reducing the speed of the neutrons generated during these reactions.
