Nuclear Power is a major new feature introduced to Factorio in version 0.15. It requires higher level technology compared to either Solar Power or Steam Boiler Power, but it offers very high power output in exchange. It's a great solution for middle- to end-game power generation and it works well in combination with other power generation techniques.
This guide is written for people who want to know exactly how nuclear power works, but don't necessarily want all the solutions. It focuses on what you should do and what you should know to get Nuclear up and running, but doesn't tell you what to do or exactly how to solve the problems.
Technology Required: Nuclear Power
> You can mine uranium ore sooner, but you'll need the Nuclear Power technology to do anything useful with it.
