Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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.

Spectral synthesis methods, in which the space-energy flux is synthesized from known flux spectra, are applied to one-dimensional, fast reactor static problems. The methods include few-group synthesis models that employ either the same trial spectra in all regions of the reactor model or different trial spectra in different spatial regions. Numerical results demonstrate that the space-energy flux can be adequately represented by these few-group synthesis models; moreover, the spatially dependent spectra agree very well with similar, “exact” flux spectra calculated by direct multigroup methods. Region-integrated reaction rates calculated with the synthesized flux spectra are in good agreement with those calculated with the flux spectra derived from direct methods.
