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 review of workforce trends in the nuclear community
The nuclear community is undergoing a moment of unprecedented interest and growth not seen in decades. The passage of the bipartisan Infrastructure Investment and Jobs Act and the Inflation Reduction Act are providing a multitude of new funding opportunities for the nuclear community, and not just the current fleet. A mix of technologies and reactor types are being evaluated and deployed, with Vogtle Units 3 and 4 coming on line later this year, the Advanced Reactor Demonstration Projects of X-energy and TerraPower, and NuScale’s work with Utah Associated Municipal Power Systems to build a first-of-a-kind small modular reactor, making this is an exciting time to join the nuclear workforce.

The University of Wisconsin–Madison inertial electrostatic confinement fusion device HOMER was used to perform current scans at low and moderate pressures, 0.3 and 1.0 mTorr of deuterium, in which the cathode voltage, current, and pressure were carefully controlled. The data was taken in short intervals to avoid the degrading effect of chamber heating on the fusion rate. Low pressure operation should harden the deuterium energy spectrum, but the low pressure also reduces target density. The results showed the fusion rates for 0.3 mTorr are about half that at 1 mTorr. Also, the 6 low pressure current scans had confirmed the approximately linear neutron production rates with respect to current. All 6 of the 1 mTorr current scans showed trends of slightly above linear neutron rates. Also, a new IEC steady state D-D neutron production record of 2.5 × 108 n/s was set at 150 kV, 100 mA, and 1.0 mTorr.
