poolpartiireaktor

A poolpartiireaktor, also known as a pool-type reactor or pool reactor, is a type of nuclear reactor where the reactor core and fuel are submerged in a pool of water. This water serves multiple critical functions: it acts as a moderator to slow down neutrons, a coolant to remove heat generated by the fission process, and a radiation shield to protect personnel and the environment.

The reactor vessel, or core shroud, typically contains the fuel assemblies and control rods. The surrounding pool of water extends above the core, providing a significant shielding layer. This design offers inherent safety features due to the large volume of water, which can absorb a significant amount of energy in the event of an emergency.

Pool reactors are often used for research purposes, isotope production, and materials testing due to their flexibility and relatively simple construction compared to other reactor designs. They can be operated at lower power levels, making them suitable for educational institutions and specialized industrial applications. Maintenance and refueling can also be performed underwater, which simplifies these operations and enhances safety. Examples of pool-type reactors include the TRIGA reactor and the research reactors found at many universities worldwide.
