Nuclear survival powers/abilities

[TheAngryOrange]

Hello. So I'm curious what sort of powers/abilities can you get from someone surviving a nuclear fireball. Sparing you the details, the energy of the nuke is irrelevant. At least in terms of what I'm asking. But Little Boy, the nuke dropped on Hiroshima, had fireball temperatures several times hotter than the core of the sun. Temperatures so hot that atoms are torn apart and stripped of their electron clouds.

As mentioned, yield is irrelevant. But if you had characters who've survived this fireball, or even ones who died but still manage to stay in one piece, what kind of powers/abilities can they be granted?

Heat resistance? Matter manipulation resistance? Quantum manipulation resistance?

Would simple be resistance to heat manipulation, the matter stuff is part of the high temperature, unless the character explicitly suffered and survive the atom stuff, resisting the temperature means they wouldn't be affected like that

Heat Manipulation, Radiation Manipulation, Matter Manipulation (ONLY If the atom stuff is mentioned.)

Oh yeah radiation too, figured it was ignored since we were focusing on the temperature
