Feedback reactivities determine the time dependence of a reactor during and after a transient initiating event. Recent analysis of control-rod drops in the Experimental Breeder Reactor II (EBR-II) has indicated that some relatively fast feedback may exist that cannot be accounted for by the linear feedback mechanisms. The magnitude of the positive insertion appears dependent on the amount of inserted reactivity and the run configuration. This phenomenon may be caused by a small, but rapid, change in core dimensions.
