Just to give this some perspective...
One ton of TNT exploding yields over 4000 megajoules of energy.
One megaton yields over 4000 terajoules: more energy than the whole Earth will use for hundreds of years, at least.
Seems to me, in order to survive a one megaton blast, one would have to counter 4000 terajoules with an equal amount of energy, at least.
Where in God's name do these "nuke survivors" get this much power from? Given the amount of energy which rains down from the sun, per square centimeter, even Superman doesn't have enough skin surface area to absorb this much power.

Why pick on Superman?
1. Ask 100 people which superhero can take a nuke, chances are, every one of them will answer "Superman."
2. Unlike those superheroes who rely on "magic" (which, as far as anyone knows, has absolutely no basis in reality), Big Blue's power depends on solar energy, which is very real and can be measured.
Thusly...
- On a sunny day, the amount of sunlight per square centimeter yields 0.1345 joules every ten seconds.
- An adult male has about 1.8 square meters of total skin surface area.
- If Superman were totally naked, he could perhaps absorb about 2500 joules in ten seconds. He needs 1.6 trillion times this amount to counter the energy of a 1 megaton bomb (4000 trillion divided by 2500).
- 1.6 trillion x 10 seconds is about 500,000 years. This is how long Kal El has to sunbathe to absorb enough power to survive 1 (one) "typical" nuclear explosion.
Thank you for your kind attention.
From here it would perhaps be better to assign the solar rad he absorbs a "secondary" position, something which triggers a far more powerful energy source, rather than being the primary energy source itself.
A character I had developed used subnanotech to draw power directly from the quantum foam, ie, by "popping quantum plumes." I imagine many of us are familiar with science's current theories on zero-point energy. Some say it's a pipe dream (which would violate laws of conservation); others say the quantum vacuum holds unimaginable degrees of power which can be utilized as long as an overall cosmic "balancing of the energy books" occurs.
Superman picked the wrong power source.
