I fail to understand how these nuclear bomb simulations require so much compute power.

Are they trying to model every single atom?

Is this a case where the physicists in charge get away with programming the most inefficient models possible and then the administration simply replies "oh I guess we'll need a bigger supercomputer"

These usually get split into nodes and scientists can access some nodes at a time. The whole thing isn't working on a single problem.
