To be more precise, the temperature difference between the inside of the reaction vessel and the water cannot be greater than a certain value or the generation of heat will cease and the difference cannot be less than a certain value or the reactor temperature will then begin to rise autonomously until the vessel melts. These curcial temperature differences are calculated by subtracting the water temperature from the optimal operating temperature of the vessel's interior. Harry
