Some Aspects of Zero Power Reactor Transfer Function

Abstract

Reactor transfer function measurements by various methods have been very active in recent years. Zero power reactor transfer functions are investigated in the present report from the viewpoint of space dependency and two energy group theory. In part [A], the space dependency of reactor transfer function is discussed, and compared with the ordinary space independent transfer function. In part it is pointed out that the transfer function derived from two energy group theory may be utilized to determine subcriticality, as well as fast and thermal neutron lifetimes.
