The surface has only been scratched in exploiting the possibilities for extracting useful information from dynamics tests. They contain all of the information in static tests (steady state is only one point in a transient) in addition to other information not available from static tests. Also, it is easier to obtain certain types of information from dynamics tests than from static tests. This is because it is possible to separate effects due to processes with different time constants in a dynamics test, but not in a static test.

The development of power-reactor testing methods that are easy and inexpensive to implement along with the development of system identifica­tion techniques (primarily from work in nonnuclear industries) should result in common use of these techniques.
