Meltdown
Until the fission products have decayed.
Because the fission products that are contained in the fuel are radioactive and produce a substantial amount of heat.

A nuclear reactor is an assembly of fuel elements (uranium usually), a moderator which can be ordinary water, heavy water, or graphite, and control rods. The reactor is made to reach criticality when uranium fuel will produce a steady power output as a result of nuclear fissions which release heat. The heat is used to produce steam which feeds a conventional steam turbine/generating unit.
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.
Known as fuel rods, these are hollow metal rods that contain the uranium fuel for a nuclear reactor.

It is produced in the fuel rods by fission of the U235 nuclei. Each fission produces a certain amount of heat, and this is transferred to the water or gas which is pumped past the fuel, by contact heat transfer.
