Web12 de ago. de 2024 · This is caused by a startup neutron source, such as Californium-252 or Plutonium-238. These metallic elements are inserted into the reactor with new nuclear fuel. As control rods are lifted from the reactor core, neutrons from the neutron source start to fire, and because there is enough fuel for a sustained reaction, we start the fission ...

Web29 de mar. de 2024 · Reactors use uranium for nuclear fuel. The uranium is processed into small ceramic pellets and stacked together into sealed metal tubes called fuel rods. … Control rods are used in nuclear reactors to control the rate of fission of the nuclear fuel – uranium or plutonium. Their compositions include chemical elements such as boron, cadmium, silver, hafnium, or indium, that are capable of absorbing many neutrons without themselves decaying. These elements have different neutron capture cross sections for neutrons of various energies.
