The turbines in railcraft serve basically as a means to convert MJ power in EU, wheras in a real-life a nuclear reactor would heat up water to produce steam, which is then piped through to a turbine room, where the steam drives the turbine rotors in order to produce actual electricity. However, making IC reactors work like this would basically require one to install Buildcraft in order to use them, and therefore I would say it's quite unlikely, unless it was added as an "upgraded" reactor system.
In fact, I suppose one could see the conductive pipes in Buildcraft as like a "pressurised" pneumatic type system rather than electrictiy, which in the grand scheme of things would make far more sense.
