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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.

Both PF1A upper coils and lower coils experienced difficult situations during the National Spherical Torus Experiment–Upgrade (NSTX-U) machine operations in 2016. There are huge up-down electromagnetic forces on PF1A terminals, coil leads, and bus bars. Therefore, further analysis and additional reinforcement supports are needed to reduce the stress on the coil terminals and leads. Structural, thermal, and electromagnetic analyses of the three-dimensional PF1A lower bus bar and coil lead model have been performed using imported electromagnetic loads with the worst cases of 96 scenarios through the global Biot-Savart stick model. The reinforcement blocks for the PF1A lower coil leads and flags and two clamps were analyzed and installed for field testing. The coil leads and bus bars used in the field testing were qualified for the normal NSTX-U operating loads allowing similar reinforcement details to be used in the real NSTX-U machine.
