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.
It can happen if the reactor fuel rods overheat, and that can happen if they are not adequately cooled after the reactor is shutdown
Most likely they would warp and jam, however damage to fuel rods is likely from overheating long before any effect on control rods.
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.
It can't explode like a nuclear bomb. It could have a steam explosion, as can any steam power plant. It is also possible for it to build up hydrogen gas if it runs too hot and damages its fuel rods, the hydrogen could explode.

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.
None whatever, unless they live in or are visiting Japan
You have a misapprehension there, it is uranium oxide that is used in fuel rods, not fossil fuel
