I was thinking of Nuclear Reactor which is controlled by Computer/Terminal or "Crane tool". The idea is to move control rods and increase/decrease cooling water flow. But this would be just reactor for users which can handle such a risky thing. But with these risk's it would generate more energy without using tons of Uranium or copper to do Condensators. Water will be pumped with pump. If possible, Steam Turbines would be awesome too, connected with steam pipe or waterproof pipes to steam turbine. Old Nuclear Reactor will be saved for newbies or lazy people.
The upper Control Rod level is, the higher they are, and more the Uranium Fuel Consumption is. Nuclear Reactor Vessel should be about 2x2 or 3x3 block-size . And while the Control Rod level is increased, Control Rod's will come trough the "Reactor"
Reactor is not planned for newbies or inexperienced. The idea is to make game more challenging and fun, also make players be "real" Nuclear Physicist.
Here is picture i made to "show" a little what i am looking for. I know it's not clear.
Picture of Control-Rod How it would raise after raising level.
