The charges are referred to as "nuclear demolition charges" but that is an old Soviet term/distinction. In this case the purity of the yield was the key. It's exponential so the last four decimals and last few nanoseconds are what hype up the yield to insane levels for such a small device. Then the magnetic lensing reflects the X-rays produced towards the core's steel super structure, flash-melting a good portion of it all at once. It's literally as if someone at the press of a button could turn large sections of the core to the consistency of oatmeal. Hence, the free-fall speeds. And all the molten steel is camouflaged in the dust. Many of the conventional charges were only there to create the dust to hide the real reactions going on at the core.

Makes sense if indeed these things exist.
