The complexity of neutron transport in terms of space, time, and neutron energy dependence is well recognized. Through the years, there have been many attempts to utilize various parameters to characterize a neutron system to help nuclear engineers to understand various applications. Parameters such as keff, neutron spectrum, average energy of neutrons causing fissions, and others are used to size up the types of the problems in a particular application. From a neutron physics viewpoint, not all the parameters used are of the same usefulness.
