WebApr 5, 2024 · The Nuclear Reactor is an installation. It uses fuel rods to produce power for the submarine. In engineered nuclear devices, essentially all nuclear fission occurs as a "nuclear reaction" — a bombardment-driven process that results from the collision of two subatomic particles. In nuclear reactions, a subatomic particle collides with an atomic nucleus and causes changes to it. See more Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of See more Mechanism Radioactive decay Nuclear fission can occur without neutron bombardment as a … See more • Nuclear technology portal • Energy portal • Cold fission • Fissile material • Fission fragment reactor • Hybrid fusion/fission See more • The Effects of Nuclear Weapons • Annotated bibliography for nuclear fission from the Alsos Digital Library • The Discovery of Nuclear Fission Archived 2010-02-16 at the See more Discovery of nuclear fission The discovery of nuclear fission occurred in 1938 in the buildings of the Kaiser Wilhelm Society for Chemistry, today part of the See more • DOE Fundamentals Handbook: Nuclear Physics and Reactor Theory Volume 1 (PDF).
