    Inside the radiative fireball, the bomb itself is rapidly expanding due to the heat generated by the nuclear reactions. This moves outward at supersonic speeds, creating a hydrodynamic shock wave at its outer edge. After a brief period, this shock front reaches and then passes the initial radiative fireball.
