The heat generated by any section of the wire that does not come into contact with the reactor core to transfer heat to the reactor must be subtracted from the total power consumed by the heater. This includes any inter reactor wire runs between the null and active reactor cores, The power consumed by each section of wire must be determined and the power adjusted accordingly.
