Bug Yellorium Rods not working?

[LeFoxxy]

So I don't know if I am doing something wrong but when I place down Yellorium blocks there is nothing inside!

So can anyone kind of help me figure this out?

Blocks?

If you want to fill the fuel rods put some ingots in the Access Port.

First off, what sgbros1 said, you need to put it in the fuel access port. It will convert the yellorium into a liquid format which will fill the fuel rod.
Second each rod column needs a control rod block on top.
Third, you need to complete the reactor multiblock.
