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.
A few
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.
Control rods that absorb neutrons. These contain some material that strongly absorbs neutrons, boron is most often used but cadmium has similar properties.
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.
No, but control rods do.
Nuclear reactors are controlled by changing the geometry of the fuel rods to slow down the reaction, dropping them into moderators, or removing them from the hot part of the reactor. The old phrase (from my day) was "ax the mandrel, she's running HOT!" meaning drop all the fuel rods into the moderator structure.

Nuclear reactions do not produce gases, except for some of the fission products which are gaseous, like xenon, but these are contained securely within the fuel rods and would only be released in the event of a fuel melt down. So nuclear power does not produce greenhouse gases.
The nuclear fuel rods in the BWR design in Japan are about 12 feet long.
Water is pumped around the fuel rods.
fuel rods and control rods
The fuel rods used in a nuclear reactor are made from uranium 235(U-235).
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.
Known as fuel rods, these are hollow metal rods that contain the uranium fuel for a nuclear reactor.
we will start with this statement cadmium rods have the property to absorb nutrons now we know that for nuclear reactions it is necessary for the neutrons to strike the nucleus of the atom and thus with the help of cadmium rods we can control the number of neutrons striking the nucleus and we can control our nuclear reactions
You have a misapprehension there, it is uranium oxide that is used in fuel rods, not fossil fuel
