Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

A study has been made to evaluate two aspects of the spectral synthesis method as formulated by Lorenzini and Robinson: (1) evaluation of spectral synthesis, relative to group collapsing, in terms of computational time, and accuracy for typical liquid metal fast breeder reactor problems; and (2) the numerical procedures used in solving the equations in two-dimensional geometries. Three trial spectra were used in the spectral synthesis method; the few-group calculations were done with 3, 4, and 8 groups collapsed from a 24-group set. Results were obtained and compared for Keff, breeding ratios, fractional power in regions, and power distributions.
