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.

How to talk about nuclear
In your career as a professional in the nuclear community, chances are you will, at some point, be asked (or volunteer) to talk to at least one layperson about the technology you know and love. You might even be asked to present to a whole group of nonnuclear folks, perhaps as a pitch to some company tangential to your company’s business. So, without further ado, let me give you some pointers on the best way to approach this important and surprisingly complicated task.

Heat transfer by laminar forced convection to a Bingham plastic in the entrance region of a circular tube is investigated. Uniform velocity and temperature profiles are assumed at the inlet of the constant wall temperature tube. All Theological properties are taken to be constants in the analysis. The governing conservation equations are solved using a finite difference technique for a range of the parameters of the problem—dimensionless plug radius ā and Prandtl number Pr. The results show that the mean Nusselt numbers—beyond an initial entrance length—are higher for Bingham plastics than for Newtonian fluids. This increase in Num becomes more significant with increasing dimensionless plug radius, while the entrance length increases with decreasing Prandtl number.
