Why can't we see the whole universe? Does the term "universe" refer to space, or to the matter in it, or to both?

I'm trying to research a particular nuclear reactor (there are sevearl types). Features should include how it works (in detail) & other info on when it was created and opened for use. The detail that I'm looking for has t be very extensive and precise (e.g how the nuclear power is generated in the reactor by the means of fission reaction of Uranium-238)
Can anyone provide me with a good source where there's everything I need to know including diagrams & stuff?
Furthermore, the nuclear reactor must have ALL info on it & when I mean all I mean ALL, so that it tells me everything about that reactor.
Thanks...
