Where can nuclear reactions occur?

One type of nuclear reactions is fusion. This usually occur under extreme conditions - extreme temperatures and pressures. This most commonly occurs in the center of stars (including our Sun); in some cases also on the surface of a star (when matter falls onto the star, temporarily producing the high temperatures required). So far, it it not economically practical to do this artificially (search for "fusion reactor") - except for the destructive H-bomb. Fusion reactions usually occur if sufficient amounts of Uranium or some other heavy elements come together. This is the case with a nuclear reactor, and an atomic bomb.
