Magnox

Magnox is a now obsolete type of nuclear power reactor which was designed and is still in use in the United Kingdom, and was exported to other countries, both as a power plant, and, when operated accordingly, as a producer of plutonium for nuclear weapons. The name magnox comes from the alloy used to clad the fuel rods inside the reactor.

Wylfa Nuclear Generating Facility contains the world's last operating Magnox reactor.
