Question about nuclear pulse propulsion

As I understand it, the idea behind "nuclear pulse propulsion" is that you have a spaceship where you explode nukes behind the ship, and then the ship sort-of "rides the shockwave", the nuclear explosions propelling the ship forward. But how can that possibly work in the vacuum of space? If there's no medium, like air, there's no shockwave, right? So what, exactly, would be propelling the ship forward?
