Ydinfissiota

Ydinfissiota, often referred to as nuclear fission, is a nuclear reaction process where the nucleus of an atom splits into two or more smaller, lighter nuclei. This process releases a significant amount of energy, along with neutrons and gamma rays. The most commonly fissile isotopes used in nuclear reactors and weapons are uranium-235 and plutonium-239.

The process is typically initiated when a fissile atom absorbs a neutron. This absorption makes the nucleus unstable, causing it to undergo fission. The resulting fragments are lighter elements, and crucially, the fission also releases more neutrons. These released neutrons can then go on to strike other fissile nuclei, initiating a chain reaction. This chain reaction is the fundamental principle behind nuclear power generation and nuclear weapons.

In nuclear reactors, the chain reaction is carefully controlled to produce heat. This heat is then used to generate steam, which drives turbines to produce electricity. Control rods, made of neutron-absorbing materials, are used to regulate the rate of fission and prevent the reaction from becoming uncontrolled.

In nuclear weapons, the goal is to achieve a rapid and uncontrolled chain reaction, releasing a massive amount of energy in a very short period. This results in an explosion. The understanding and application of ydinfissiota have had profound impacts on energy production, medicine, and international relations since its discovery in the late 1930s.
