How does a nuclear reactor work

How does nuclear fission work? In principle, any nucleus, if brought into a sufficiently high excited state, can be split. The excitation energy must be above the critical energy (E crit) or threshold energy for fission to occur.; For heavier nuclei with Z > 90, the critical energy is about 4 to 6 MeV for A-even nuclei and generally is much lower for A-odd nuclei.

Nuclear reactors use uranium that will be processed into small ceramic pellets and jointly piled into fuel rods. A fuel combination can be formed by a group of more than 200 fuel rods. Typically, a reactor core can be built through these assemblies depending on the power level. In a nuclear reactor vessel, the fuel rods are placed underwater.Vocabulary. Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe, and energy is what holds the nucleus together. There is a huge amount of energy in an atom 's dense nucleus. In fact, the power that holds the nucleus together is officially called the " strong force ." For power reactors, the reactor can behave differently at power conditions due to the presence of reactivity feedbacks. Power reactors are initially started from hot standby mode (a subcritical state at 0% of rated power) to power operation mode (100% of rated power) by withdrawing control rods and boron dilution from the primary source coolant.
