OSTI ID:4080799
The inhour equation of a fast reactor puised by periodical reactivity variations is derived by two techniques. The first method defines a mean multiplication factor which is the ratio number of neutrons produced during one period to number of neutrons absorbed during one period. The second method uses a multiplication factor for the mean power which is defined by the ratio number of delayed neutron emitters formed during one power pulse to the number of delayed emitters decaying during one power pulse. The inhour equation obtained by the second method shows the influence on the inhour equation of the time intervals during which the reactor is subcritical. For cases in which the influence of these time intervals is negligible, the equivalence of the two derivations is shown. (auth)
