How did Godzilla become nuclear?

How did Godzilla become nuclear? Godzilla’s nuclear pulse in King of the Monsters (and how he chose to use it) is reminiscent of the final act of Godzilla 2000. When Orga was trying to absorb Godzilla’s energy, Godzilla allowed him to continue, and fired up a nuclear pulse to destroy him.
