Nuclear fission produces energy for nuclear power and drives the explosion of nuclear weapons. Both uses are possible because certain substances called nuclear fuels undergo fission when …

Jan 2, 2026 · Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the …

Nuclear fission is the process where the nucleus of an atom splits into two or more smaller nuclei and other particles. These particles can include neutrons, alpha particles (helium nuclei), beta …

Nuclear fission is the process of splitting a large atom into two smaller atoms and releasing a LOT of heat, making it an extremely energy dense resource. That heat is used to boil water, make …

Aug 21, 2023 · Nuclear fuel—uranium Uranium is the fuel most widely used by nuclear plants for nuclear fission. Uranium is considered a nonrenewable energy source, even though it is a …

May 13, 2023 · Nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei. This process often produces …

Jun 9, 2025 · Fission is the splitting of an atomic nucleus into two or more lighter nuclei accompanied by energy release. The original heavy atom is termed the parent nucleus, and …

Nuclear fission is the process used in today's nuclear power plants. It occurs when the nucleus—the central core of an atom—typically of a heavy element, such as uranium or …

May 25, 2025 · Nuclear fission is the process by which the nucleus of an atom splits into two or more smaller nuclei, accompanied by the release of a large amount of energy. This seemingly …

When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission (see diagram below). Each time a U-235 nucleus splits, it releases two or …
