Nuclear weapons aren't that tough on a nation-scale to produce. It's generally thought that places like Saudi Arabia, Japan, Australia, etc. could make a nuclear weapon in a few months if they really wanted.
Can you elaborate on that? Are the processes for making fuel for energy so different from the processes for bomb material that one doesn't help the other at all?
-Many more people become atomic experts, and they may be hired by weapons programs in the future.
-We will learn how to deal with nuclear materials more efficiently - good for energy, but maybe also good for building weapons.
-With more nuclear material being manufactured for energy, will it be easier to hide weapons manufacturing in the mix?
I'd like to acknowledge that I'm speaking from ignorance here. I don't know much about nuclear technology.
