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 252Cf prompt-fission-neutron spectrum has been measured by time-of-flight techniques over the energy range 0.5 to 13 MeV. Significant analytical and experimental improvements over earlier measurements were employed. The data were simultaneously analyzed with the angular pattern data of Bowman et al., using a model which includes anisotropy of emission in the neutron fragment coordinate system and a stationary source. Based on this analysis, the mean energy is found to be 2.105 ± 0.014 MeV. It is also concluded that the fragment emission spectra are highly anisotropic. The anisotropy is dictated by the data presented here, rather than by angular patterns. The existence of the stationary source is supported by both data types. A Maxwellian fit to the data provided a temperature parameter of 1.406 ± 0.015 MeV. While the spectrum clearly deviates from a Maxwellian, this simple representation was found to be adequate to ±5% from 0.7 to 8.0 MeV.
