I'm developing a new Mod: a building that works similar to Nucler Reactor... but

I need to change the Reactor Prototype to generate power directly, and not heat.
I know how to get rid of pipes graphics, but the prototype oblige me to keep the connections, and the main stuff: I don't know how to produce power from this prototype base, like steam-engines, but consuming a fuel like Nuclear cell instead steam.
Someone can help me to find how to do this, please?
Thank you so much.
