kjernenhet
Kjernenhet, also known as nuclear core or nuclear reactor core, is a critical component of a nuclear reactor. It is the region where the nuclear fission reactions take place, releasing a significant amount of energy in the form of heat. The core consists of fuel assemblies, which contain nuclear fuel pellets, typically made of enriched uranium or plutonium, encased in metal cladding. These fuel assemblies are arranged in a specific pattern within the core to optimize neutron moderation and fission.
The core is surrounded by a coolant, usually water, which absorbs the heat generated by the fission
The core's design and operation are crucial for the safe and efficient functioning of a nuclear reactor.
