Big Reactors are highly reliant on the placing of the rods and the "coolants" inside. In this one, I have cryotheum in between the rods and resonant ender everywhere else. It can produce 17k Rf/t. It can produce more if I turned it into a Active cooled reactor, but I don't have the resources for that just yet.
