There is some difficulty in analyzing the axial spatial kinetics of a reactor by means of modal transfer function technique because of the existence of the temperature integral effect resuiting from coolant flow. The modal transfer function technique has such merit, however, that it gives qualitative views in the kinetic character of the reactor. The modal transfer function technique is developed to analyze the axial spatial kinetics of the Calder Hall type reactor. Interesting results from the viewpoint of control theory are obtained. It is found that: modal interaction acts as negative feedback, and therefore that the interaction can be neglected in the case of the stability criterion: and that the control system can act as positive feedback at some insertion depth of the control rod, and there is some possibility that negative feedback might not be attainable at any insertion depth of the control rod, depending upon the heat transfer character and temperature coefficient of the re actor.
