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.
Division Spotlight
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.

Remembering Charles E. Till
Charles E. Till
Charles E. Till, an ANS member since 1963 and Fellow since 1987, passed away on March 22 at the age of 89. He earned bachelor’s and master’s degrees from the University of Saskatchewan and a Ph.D. in nuclear engineering from Imperial College, University of London. Till initially worked for the Civilian Atomic Power Department of the Canadian General Electric Company, where he was the physicist in charge of the startup of the first prototype CANDU reactor in Canada.
Till joined Argonne National Laboratory in 1963 in the Applied Physics Division, where he worked as an experimentalist in the Fast Critical Experiments program. He then moved to additional positions of increasing responsibility, becoming division director in 1973. Under his leadership, the Applied Physics Division established itself as one of the elite reactor physics organizations in the world. Both the experimental (critical experiments and nuclear data measurements) and nuclear analysis methods work were internationally recognized. Till led Argonne’s participation in the International Nuclear Fuel Cycle Evaluation (INFCE), and he was the lead U.S. delegate to INFCE Working Group 5, Fast Breeders.

A molten salt FLiBe is proposed to be one of candidate materials for coolant and breeder in a fusion blanket. However, it is high Pr-number fluid with large viscosity. Therefore, applying it as the coolant for high surface heat flux conditions, we have to develop a new methods to enhance heat transfer of molten FLiBe flowing in a channel by an adequate active promoters. Through the present study of numerical analysis, it is clarified that an averaged Nusselt number of molten FLiBe laminar flow in a channel filled with the porous medium is higher than that in a normal smooth pipe. The larger enhancemnet can be increased with increasing flow velocity, however, the averaged Nu number shows a maximum value because the heat transfer in the radial direction perpendicular to the flow axis becomes relatively reduced with the increase of the flow velocity.
