Nuclear reactor core - Wikipedia
A nuclear reactor core is the portion of a nuclear reactor containing the nuclear fuel components where the nuclear reactions take place and the heat is generated. [1] Typically, the fuel will be low- enriched uranium contained in thousands of individual fuel pins.
Reactor Core - Nuclear Power for Everybody
A nuclear reactor core is a key component of a nuclear reactor. In reactor physics, the nuclear core is a bounded region, where neutron multiplication occurs, and chain reactions occur. The reactor core contains the nuclear fuel (fuel assemblies), the moderator, and the control rods.
Core Description | MIT Nuclear Reactor Laboratory
The core consists of 27 positions, most of which are filled with fuel elements, such as the one shown in position C-9. The remaining three positions are filled with either a solid aluminum "dummy" element or an In-Core Experiment.
NUCLEAR 101: How Does a Nuclear Reactor Work?
2023年8月2日 · Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity.
Reactor Core - Explore Nuclear
The reactor core is where the magic (nuclear fission) happens to create energy. A reactor core is comprised of 4 basic systems and components: This includes the rods and assembly structure and is the ‘food’ for the reactor. Be it liquid or gas, circulates around the fuel to absorb and transfer heat produced during fission.

2021年3月9日 · The central portion of a nuclear reactor, which contains the fuel assemblies, moderator, neutron poisons, control rods, and support structures. The reactor core is where fission takes place.
Design of the Reactor Core for Nuclear Power Plants | IAEA
This Safety Guide provides recommendations on meeting the safety requirements established in IAEA Safety Standards Series No. SSR-2/1 (Rev. 1), Safety of Nuclear Power Plants: Design, applied to the design of the reactor core for nuclear power plants.
Reactor Core - an overview | ScienceDirect Topics
The core of the reactor is its heart, the place where the nuclear fuel is placed and where the nuclear reaction takes place. The fuel is most frequently formed into pellets roughly 2 cm in diameter and 1–2 cm long.

Reactor core | nuclear reactor component | Britannica
In nuclear reactor: Core. All reactors have a core, a central region that contains the fuel, fuel cladding, coolant, and (where separate from the latter) moderator. The fission energy in a nuclear reactor is produced in the core. Read More
