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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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 pile oscillator technique was used to measure the Doppler effect with heated small samples in neutron spectra typical of steam cooled fast reactors. Samples of UO2 in various enrichments, especially depleted UO2, were measured up to 1000°K, and also samples of PuO2 diluted with Al2O3. The results were analyzed by a method which properly accounts for the resonance interaction between the hot sample and the cold environment. The results with the UO2 samples where 238U gives the major contribution to the Doppler effect were in agreement with calculations within about 10%, though changes of the effect between different assemblies, in some cases, were not well reproduced. The experiments with PuO2 samples were designed to give integral information on alpha of 239Pu in the range 0.1 to 5 keV. It is shown that experiment and calculation agree within about 25% if high alpha values similar to those of Gwin are used.
