Hopefully the few computers needed do not use generalist OSes and aren't connected to the Internet either ?

IIRC, some nuclear readout panels were accessible over the public internet using badly secured VNC, so I think that's not the case.

Should we be concerned then about nuclear weapons to be hacked too ?

Not to the point of detonating them - they have a lot of physical safeguards.
