WebJun 30, 2024 · In a conventional nuclear reactor, the main line of defense against a meltdown is the fuel control rod, which power plant operators use to control the fission rate in the core. WebIn nuclear physics, a nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series of these reactions. The specific nuclear reaction may be the fission of heavy isotopes (e.g., uranium-235, 235 U). A nuclear chain reaction …

WebThe spontaneous fission of uranium-238 and uranium-235 leaves trails of damage in the crystal structure of uranium-containing minerals when the fission fragments recoil through them. These trails, or fission … WebApr 1, 2024 · Fusion. Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly radioactive fission products.
