Building my first nuclear reactor I realized that there is no indication of what I should put inside it. It just says "fuel" when hovering over the input cell.
Same for all smelters though they are explained in scenarios at least.
I think that missing specs that make player googling is a bug.

Thanks for the report. The tooltip will now show what fuel a given entity accepts.
If you want to get ahold of me I'm almost always on Discord.
