I've downloaded:
Thermal Expansion
Thermal Foundation
CoFHCore
Big Reactors

I have no Reactor Casing, Reactor Controller, etc. I cannot build a reactor. Please help.

Anyone planning on helping?

Which versions are you using?

I figured it out. what I am having problems with is having the reactor produce RF... I am also having problems using the reactor to provide the turbine what it needs to run.
