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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

The Doppler effect in 238U and 232Th metal has been measured by the activation technique in a 1/E spectrum. The samples consisted of foils (or packets of foils) irradiated under cadmium near the center of the Stanford University Pool Reactor. All the measurements were performed at a heated sample temperature of 500 °K. The values of the surface-to-mass ratio (S/M) of the uranium samples ranged from 1 to 20 cm2/g; two values of S/M in the same range were used for thorium. Experimental values of the Doppler ratio, R, defined as the ratio of heated sample activity to unheated sample activity, are shown to be in good agreement with ratios of resonance integrals calculated by ZUT-TUZ and/or GAROL.
