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.
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.

A day in the life of the nuclear community
The November issue of Nuclear News is focused on the individuals who make up our nuclear community.
We invited a small group of those individuals to tell us about their day-to-day work in some of the many occupations and applications of nuclear science and technology, and they responded generously. They were ready to tell us about the part they play, together with colleagues and team members, in supplying clean energy, advancing technology, protecting safety and health, and exploring fundamental science.
In these pages, we see a community that can celebrate both those workdays that record progress moving at a steady pace and the exceptional days when a goal is reached, a briefing is delivered, a contract goes through, a discovery is made, or an unforeseen challenge is overcome.
The Nuclear News staff hopes that you enjoy meeting these members of our community—or maybe get reacquainted with friends—through their words and photos.

The U-Pu-Zr metallic fuels contain multiple phases whose properties and distributions evolve due to factors such as fission, nuclear transmutation, and elemental redistribution under the influence of chemical and thermal gradients. An understanding of experimental data about phases, phase relationships, and phase properties in the U-Pu-Zr system is needed to enable mechanistic modeling of these phenomena and guide future research.
Although U-Pu-Zr alloys have been investigated for more than 60 years, relatively little reliable experimental information is available. Information about the technologically important alloy U-20Pu-10Zr (weight percent) is even more limited. The U-Pu-Zr alloys are difficult materials to study experimentally, and it is therefore important to understand what results have already been obtained, how reliable they are, and where they were reported.
This critical review provides a thorough compilation and critical assessment of the available experimental data involving properties of U-Pu-Zr phases, phase transitions, and phase diagrams, with particular attention to alloys with compositions close to U-20Pu-10Zr (weight percent). It is intended as a resource for fuel designers and modelers and a guide for prioritizing future experimental work.
