Nuclear fuel rods could not go through the Earth because of the intense temperature and thickness of the Earth's layers. A while back somewhere in Russia , people made a giant hole in the ground (i don't know how many miles wide it was) and sent giant super drills inside. They got 7 miles deep as far as i can remember , that barely scratched the surface of the Earth. They could not continue because the temperature was too intense and the rock was too tough to work with (diamond super drills were needed to pierce the rock but was too expensive). If we or any other country would have thought of another method it would have surely been used by now.
Water is pumped around the fuel rods.
Known as fuel rods, these are hollow metal rods that contain the uranium fuel for a nuclear reactor.
The length of time we see fuel rods left in the core of a reactor will depend on the time it takes to deplete the nuclear fuel in those rods. Reactor design, specifically fuel rod design, and the rate at which the fuel is consumed during operation all have an effect. Typical life of the fuel in a nuclear reactor at a power station is several years.
Perhaps you mean the water that acts as moderator and fuel coolant
The fission happens in the fuel, which is usually in fuel rods inside the reactor. The rods are spaced at a particular distance apart and fill the reactor.
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).
No, but control rods do.
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.

You have a misapprehension there, it is uranium oxide that is used in fuel rods, not fossil fuel
A few
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.
A 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.
It releases heat through absorption of the kinetic energy of the fragments of fission in the material of the fuel rods (talking of nuclear reactors, not weapons)
