I wouldn't call the nuke a kid-friendly joke as much as I would a mistake. It's pretty ridiculous, but not humorous in the conventional way.

I haven't seen the movie so forgive me for opening my mouth, but from looking at that scene I've always thought it was a kind of self-ironic, savvy wink - i.e. "how much more can our action hero survive without a scratch? oh that's right, let's just turn the rules of reality into a cartoony farce... he survives a NUCLEAR EXPLOSION!!" let's make it really, really silly... by making him fly off in a fridge! like their first design for the Back to the Future time machine design, right... lol, that would've been goofy if they'd done that!".

It's like someone did a 24 reboot on cinema, and they had Jack Bauer do all kinds of silly stuff like roundhouse kick people around the globe (or less extreme, maybe) as a form of popcultural in-joke.

But hey, just rambling.
