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.

Transmission measurements on natural iron samples were carried out at the Nevis Synchrocyclotron to determine the minima in the total cross section occurring between 10 and 500 keV. We used the NVS 200-m time-of-flight system and obtained an effective fwhm resolution of ≈0.6 nsec/m for these measurements. Values of the total cross section at the minima points were determined by the transmission-of-the-difference method for four thick samples ranging in inverse thickness (1/n) = 1.53 to 0.38 b/atom. Our value of the cross section at the important minimum at 24.4 keV is (0.51 ± 0.02) b. This value is close to the one appearing in the KEDAK data file (0.557 b), but considerably higher than the values in ENDF/B-I (0.15 b) and ENDF/B-II (0.285 b) files. Our value is in agreement with recent integral spectral measurements at RPI which show a preference for a value close to the KEDAK evaluation.
