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.
Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

An understanding of thermal hydraulics, its basic phenomena, and its application to nuclear power plants is vital to safe as well as efficient design and operation. Thermal hydraulics for two-phase flow and heat transfer with nuclear applications has been studied for roughly 50 years, and the current body of knowledge is extensive. Yet, there remain safety issues, and the licensing of new light water reactor designs or new analysis methodologies is rarely simple. This is due to the state of the art in reactor thermal hydraulics as well as the perspective that the regulator, in this case the U.S. Nuclear Regulatory Commission (NRC), has toward that field of study.
This paper discusses the state of the art in nuclear thermal hydraulics, the regulator’s unique role and perspective, and a view of current challenges. The discussion is meant to point out how the regulator’s perspective has been shaped and hopefully provide some guidance on fulfilling research needs for future applications that may need NRC review.
