What other mods do you have (especially base and core mods)? Can you try it on clean MC instance without any other mods, just Forge+IC2+Nuclear Control?
I was testing with CodeChickenCore and NEI(core-mods nothing else) but also clear instal with just IC2+NC.
[EDIT] Did another clear test today with latest IC2 and forge - R.Click still dont work. Version proof:
