How fast does a nuke explode?
Generally, a faster detonation speed results in a higher yield, and vice versa. Modern nuclear weapons nowadays (300–500 kilotons) have a detonation velocity of up to 800km/sec. I assume you mean the light & heat waves; these would move close to the speed of light.

An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration.
How hot is a nuke?
For this reason, thermonuclear weapons are often colloquially called hydrogen bombs or H-bombs. A fusion explosion begins with the detonation of the fission primary stage. Its temperature soars past approximately 100 million Kelvin, causing it to glow intensely with thermal X-rays.
