Nonseparable Space-Time Transients Resulting from Changes in Inlet Coolant Temperature

An approximation scheme for calculating the detailed kinetic response of a reactor during a transient in which the time and space behaviors of the neutron flux are not separable has been applied to two reactor models more realistic than the one used previously to test the validity of the method. Results of applying the approximation method to a one-dimensional two-group reactor model and a two-dimensional two-group model are presented.
