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.
Meeting Spotlight
Conference on Nuclear Training and Education: A Biennial International Forum (CONTE 2025)

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.

Neutron-induced fission cross sections of 233U, 235U, 239Pu, and 241Pu have been measured up to 30 keV. These measurements were performed with samples cooled down to liquid nitrogen temperature and with a nominal resolution of 1 nsec/m, using the 60-MeV Saclay LINAC as a pulsed-neutron source. The agreement with previously published results is within 3% for 235 U in the energy range 60 eV to 10 keV, and 6% for 233U below 1220 eV. For 239Pu and for 241 Pu in the energy ranges 0.7 to 7 keV and 10 to 20 keV, the agreement is also within 6%. Total errors are a function of target material and incident neutron energies and hence are estimated to lie between 3 and 7%. The existence of an intermediate structure is demonstrated in the fission cross section of 239Pu.
