ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

A working group was created in 2002 by the Generation IV International Forum for the purpose of developing an internationally accepted methodology for assessing the proliferation resistance of a nuclear energy system (NES) and its individual elements. A case study was performed by the working group using this methodology to assess the proliferation resistance of a hypothetical NES called the Example Sodium Fast Reactor (ESFR). This work demonstrates how the proliferation resistance assessment methodology can be used to provide important information at various levels of details to NES designers, safeguard administrators, and decision makers. The study analyzed the response of the complete ESFR NES to different proliferation and theft strategies. The challenges considered include concealed diversion, concealed misuse, and "break-out" strategies. This paper describes the work done in performing a qualitative assessment of concealed diversion scenarios from the ESFR.
