Description: Plutonium-238 is an important heat producing isotope which is being used in increasing amounts as fuel in isotopic power generators for space, terrestrial, and oceanographic applications. Only within the past few years has the quantity of plutonium-238 become large enough to be considered as a potential nuclear criticality hazard. In order to insure nuclear criticality safety in the storage, processing and assembly of devices containing plutonium-238, a program has been established at Mound Laboratory to investigate the nuclear criticality properties of this isotope. This paper will summarize what is presently known about the criticality behavior of plutonium-238, what are some of the criticality controls used as Mound Laboratory for processing plutonium-238, and what measurements are needed in order to establish a Nuclear Safety Guide for Plutonium-238.
