Uranium, plutonium, thorium as nuclear fuels.
Heavy water and water as cooling agents or moderators.
Zirconium and stainless steels for nuclear rods cladding, calandria, pipes, etc.
Also graphite, helium, beryllium, cadmium, indium, silver, gadolinium, etc.
We look to the naturally occurring element uranium as a nuclear fuel.
Hafnium can be used as a material for control rods in nuclear reactors. This element has a high neutron absorption cross section, and it appears as a big target for neurtons.
Uranium is a natural chemical element, metal, solid, toxic, radioactive, reactive, very dense, used as fuel in nuclear reactors, used in nuclear bombs, used in alloys for tankks armors, etc.
Uranium
There may be Radium, Thorium, Uranium or even Plutonium which can be used in nuclear reactors.
Uranium.
Well, as nuclear reactors are nuclear reactors, nuclear reactors are not used inside nuclear reactors.
Uranaium U
To make fuel rods for nuclear reactors
Uranium is a radioactive element used to fuel nuclear reactors. It is a nuclear fuel.
We look to the naturally occurring element uranium as a nuclear fuel.
Uranium (U) Or Plutonium (Pu)
radioactive element like uranium, plutonium......etc depends which type of nuclear reactor.
Usually Uranium 235 but sometimes Plutonium 239
Hafnium can be used as a material for control rods in nuclear reactors. This element has a high neutron absorption cross section, and it appears as a big target for neurtons.
You probably are thinking of plutonium
Any fissile material would do, but Uranium is the most common.
