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.
Meltdown, also it's not just the fuel rods that melt, structural supports, control rods, etc. can melt when this happens.
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.
This happens in the fuel rods, the energy released by nuclear fission appears initially as kinetic energy of the fission fragments, which is quickly turned into thermal energy as the fragments slow down and are stopped in the fuel. Thus the fuel rods heat up and transfer thermal energy to the coolant, which in most reactors is water but can be gas or liquid metal.
You have a misapprehension there, it is uranium oxide that is used in fuel rods, not fossil fuel
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.
Nuclear fuel rods are heated, then dipped in water, causing the water to turn into heat, creating steam. It's completely clean, except when you have to dispose of the Nuclear Fuel Rods.
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.

Known as fuel rods, these are hollow metal rods that contain the uranium fuel for a nuclear reactor.
