It's not clear exactly what you mean here.
If you're asking how a nuclear explosion is prevented in a stored nuclear device, the radioactive material is kept separated into pieces below the critical mass at which normal radioactive decay becomes a runaway chain reaction.
It's also possible to keep a pile subcritical by the use of neutron-absorbing "damper" materials.
If you're asking "if a nuclear bomb went off, what could protect you from the explosion"... then a sufficient quantity of dense, strong material would do so. The quantity required depends on the material, but this is basically the purpose of a "bomb shelter"... it's a structure designed to withstand the shock wave of a nuclear blast, either because it has thick sturdy walls or because it's underground with the ground itself doing the bulk of the work of the barrier.
No such explosion ever happened.
Chemical energy- to begin the explosion- and nuclear energy- the main explosion.
In any explosion (conventional or nuclear) most of the damage is from blast effects.

nuclear explosion?
When and what explosion? One of the nuclear test shots. If so which?Remember Chernobyl was not a nuclear explosion, it was a steam explosion and graphite fire.
The only nuclear explosions in Japan were the two in WW2, on Hiroshima and Nagasaki.However I believe you meant the Japanese nuclear reactorexplosion, which was not a nuclear explosion it was either a steam explosion and/or a hydrogen/oxygen chemical explosion. That occurred at Fukushima.

Nuclear explosions are not controlled. Nuclear reactors are controlled.The first controlled nuclear reaction in the US was on December 2, 1942.The first nuclear explosion in the US was on July 16, 1945.
There are many games that involve nuclear explosion. The most highly rated game to feature a nuclear explosion as its main theme, was the popular game Half Life.
Most illnesses were cancer related because of the ionising radiation in the nuclear fall-out after the explosion.
