In order to make reactors even more efficient and advanced, I suggest an external cooling system.
A set of 2 machines and a pipe.
Heat absorber is placed inside 3x3x3 grid near the reactor. It can absorb up to triple amount heat compared to water. Though it must be connected to the cooler outside. Efficiency will vary depending on cooler surrounding (3x3x1 grid).
-0.125h/t per each lava block
0.125h/t per each solid block
0.250h/t per each air block
0.375h/t per each water block
Since cooler is a cool industrial equipment, it will consume 2eu/t while active.
Now, the recipes:
Heat absorber:
We all know reactor can easily reach 10000 heat or more. That's why we need a special plating to ensure heat absorber won't melt.
Even then, iridium plating will melt once reactor reaches 12100 heat.
