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.

The reality of radiation
Rep. Brandon Williams
Rep. Byron Donalds
For many Americans, the word “radiation” is often associated with fear of the unknown, yet the medical and scientific reality is that radiation is ever present in nature and is beneficial to human life. The truth behind radiation historically has been distorted and stigmatized—even the U.S. Nuclear Regulatory Commission recognizes that “radiation is naturally present in our environment, as it has been since before the birth of this planet.”
To embrace a responsible, low-carbon energy future, the American public should be aware of the beneficial applications of radiation instead of fearing it due to unsubstantiated hysteria generated by opponents of responsible nuclear energy.

Experiments and analysis in the 2 years since the 2015 Target Fabrication Meeting have resulted in further evolution of the requirements for high-performance layered implosions. This paper is a status update on the experimental program and supporting modeling, with emphasis on the implications for fabrication requirements. Previous work on the capsule support has continued, with various other support options being explored in experiments and modeling. Work also continues on ablator composition nonuniformities, with important new results from CH experiments on Omega, and the first three-dimensional X-ray transmission measurements of Be capsules on the National Ignition Facility. Work on hohlraums continues to include near-vacuum hohlraums and U hohlraums without a gold lining. Overall, the understanding that has been achieved, along with the progress in fabrication technology, represents good continuing progress toward the goal of fusion in the laboratory.
