1.You can create a small animation of the construction of the reactor.
2.What is that liquid that cools the reactor.

First of all thank you for the translation! But it has already been added through #2.

However I’m not entirely sure what you mean with the animation.

And what materials and fluids can be used inside the reactor is planned to be added soon.

I meant a little animation of building a reactor, as is in the book about Tinkers Construct (Furnace).

I think that's a little out of the scope of this project. I might do it later, but for now I'll close it.
