Control Rods in Nuclear Reactors - Stanford University

WebNuclear fission takes place in a nuclear reactor, which is an enclosed vessel containing a set of nuclear fuel rods that are typically made of uranium or plutonium. The fuel rods are surrounded by a moderator, typically water or graphite, which helps slow down the neutron particles and causes the uranium or plutonium atoms to split. WebFission chambers are ionization detectors used to detect neutrons. Fission chambers may be used as the intermediate range detectors to monitor neutron flux (reactor power) at the intermediate flux level. They also provide indications, alarms, and reactor trip signals. The design of this instrument is chosen to provide overlap between the source ... fmc fichtner
