Yeah the System is gonna work with Fuel Efficiency based on Neutron Count. The part in the Changelog stating “360 000 000 000 HU per Unit of U-235 at Max Efficiency” is gonna be exactly that.
The Reason for this kinda neutron economy is also that it makes it possible to just have it running as an RTG by itself without any Redstone Controls, though ofcourse that is very inefficient but still easy.
Now with the Neutron Economy you will have situations where you get exponential growth until your Reactor cant handle the Heat anymore no matter how much Coolant you dump in and then BOOM.
So excuse me now, I gotta write code instead of this post XD
