-            logic is that each tick, the heating rate worth of coolant steps between:
-                reactor tank
-                reactor heated coolant outflow tube
-                boiler/turbine tank
-                reactor cooled coolant return tube
-            so if there is a tick where coolant is no longer present in the reactor, then bad things happen.
-            such as when a burn rate consumes half the coolant in the tank, meaning that:
-                50% at some point will be in the boiler, and 50% in a tube, so that leaves 0% in the reactor
