Nuclear fission - Wikipedia

In nuclear physics and nuclear chemistry, 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. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.

Fission | Physics

Nuclear fission is a reaction in which a nucleus is split (or fissured).Controlled fission is a reality, whereas controlled fusion is a hope for the future. Hundreds of nuclear fission power plants around the world attest to the fact that controlled fission is practical and, at least in the short term, economical, as seen in Figure 1.

Nuclear Fission and Nuclear Fusion

Nuclear Fusion. The graph of binding energy per nucleon suggests another way of obtaining useful energy from nuclear reactions. Fusing two light nuclei can liberate as much energy as the fission of 235 U or 239 Pu. The fusion of four protons to form a helium nucleus, two positrons (and two neutrinos), for example, generates 24.7 MeV of energy.

Nuclear Fission Chain Reaction

Nuclear Chain Reaction. It was pointed out in the preceding articles that the neutron-induced fission reaction is the reaction, in which the incident neutron enters the heavy target nucleus (fissionable nucleus), forming a compound nucleus that is excited to such a high energy level (E excitation > E critical) that the nucleus splits into two large fission fragments.

How Nuclear Weapons Work | Union of Concerned Scientists

Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion. The explosives compress nuclear material, causing fission; the fission releases massive amounts of energy in the form of X-rays, which create the high temperature and pressure needed to ignite fusion.

Nuclear Fission - Fission Reaction

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a large amount of energy. In nuclear physics, nuclear fission is either a nuclear reaction or a radioactive decay process.

Chapter 13 NUCLEAR FISSION

Principles of Nuclear Fission In Table 12-1 we listed examples of radioactive nuclei that are important in nuclear fission. By far the most important one is uranium-235 (U-235). It is the principal constituent of the fuel rods in a nuclear reactor. In 235 grams of U-235 there are as many as 6x1023 atoms,

Dec 27, 2017· Nuclear fission is a process in nuclear physics in which the nucleus of an atom splits into two or more smaller nuclei as fission products, and usually some by-product particles. Hence, fission …

Nuclear Fission | Boundless Chemistry

Nuclear fission: In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.

14 Advantages and Disadvantages of Nuclear Fission ...

The advantages and disadvantages of nuclear fission show us that when it is used appropriately, it can be an amazing benefit to society. When it is used incorrectly, this technology has the power to destroy life as we know it.
