Usually, the rods themselves are made of Uranium-238. The fuel inside the rods is Uranium-235, which is highly fissionable. The Uranium-238 is very heavy, and slows down the neutrons so that they can properly strike the U-235 atoms.

∙ 11y agoA fuel rod is of 3-5m long made of zirconium alloys and containing uranium oxide pellets, which provide fuel for nuclear reactor. Fuel rods are assembled into bundles called as fuel assemblies and are loaded individually in to the reactor core.

∙ 11y agoA nuclear fuel rod is a tube filled with nuclear fuel. The tube part is made of material that allows neutrons to pass freely through, so the fuel can undergo reaction unhindered. The rods are put together in groups called bundles, which are attached together so they can be handled together.
There is a link below to the section in an article on nuclear fuel that explains the fuel rods. Pictures are there as well.

∙ 13y agoThe fuel rod is a component of the nuclear fuel bundle; the rod (made from zircaloy 4 or from a special stainless steel) contain the nuclear fuel in the form (generally) of uranium dioxide sintered pellets.

What part of the nuclear reactor is the fuel located in?
The nuclear fuel is found in the fuel rods. These fuel rods are formed into fuel bundles called fuel assemblies, and together they make up the reactor core.
How much do nuclear fuel rods weigh?
A few
Can nuclear fuel rods overheat and explode?
In a 'meltdown', the nuclear fuel rods will overheat and melt, not explode. It is the build-up of pressure within the containment vessel that can cause an explosion.
What happens if nuclear fuel rods touch?
The cannot as they are inserted in holes in steel support frames that hold several dozen fuel rods. When changing fuel, complete steel support frames are switched and individual rods are not handled.
An energy source that heats fuel rods is?
Nuclear Fission.Generally Uranium, but some reactors use Plutonium nuclear fission.
How tall are the nuclear fuel rods in japan?
The nuclear fuel rods in the BWR design in Japan are about 12 feet long.
What is the next step in a nuclear reactor after nuclear fission occurs in fuel rods?
Water is pumped around the fuel rods.
What rods housed within a nuclear reactor?
fuel rods and control rods
What are fuel rods in nuclear plants made of?
The fuel rods used in a nuclear reactor are made from uranium 235(U-235).
Does fuel rods slow down nuclear reactions?
No, but control rods do.
What part of the nuclear reactor is the fuel located in?
The nuclear fuel is found in the fuel rods. These fuel rods are formed into fuel bundles called fuel assemblies, and together they make up the reactor core.
What rods hold pellets of uranium?
Known as fuel rods, these are hollow metal rods that contain the uranium fuel for a nuclear reactor.
What happens to fuel rods that are used to create nuclear fission?
You have a misapprehension there, it is uranium oxide that is used in fuel rods, not fossil fuel
How much do nuclear fuel rods weigh?
A few
Is silver used in the operation of nuclear power plants?
No, Enriched Uranium-235 is used in a nuclear reactor as the fuel in the fuel rods and boron is used in the control rods.
Can nuclear fuel rods overheat and explode?
In a 'meltdown', the nuclear fuel rods will overheat and melt, not explode. It is the build-up of pressure within the containment vessel that can cause an explosion.
Are the control rods part of the fuel assemblies in nuclear reactors?
No, control rods are not a part of the fuel assemblies in nuclear reactors. They are separate "pieces" in the core, and essentially fit in "spaces" between fuel bundles.
