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
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

Senate committee advances NRC nominee Matthew Marzano
Marzano
The U.S. Senate Environment and Public Works Committee voted 10–9 last week to advance the nomination of Matthew Marzano to serve on the Nuclear Regulatory Commission. It was a party-line vote, with all Democrats supporting Marzano and all Republicans voting “no.”
Marzano was nominated by President Biden in July to fill the open NRC seat, and the EPW Committee held a hearing in September on his nomination. His nomination will now go to the Senate for a vote, but it is not certain whether that will happen before the end of the year, in which case his nomination process would start over in 2025.
The five-member commission has been without a tiebreaker vote since June 2023 when Jeff Baran’s term expired.

The tomography of fusion plasmas provides local information on plasma emissivity from line-integrated measurements (projections). However, the corresponding inversion task presents an ill-posed and often underdetermined problem. Compared to industrial and medical tomography systems, data in fusion research are spatially sparse due to the limited number of lines of sight, and they may vary rapidly in time. Therefore, dedicated inversion techniques have been developed that allow for lower spatial resolution and implementation of a priori information and constraints. In this contribution, the main inversion techniques used today are reviewed, with working results and challenges outlined. Special attention is given to techniques that allow for rapid tomography inversions, because of their future potential for real-time applications, and a new combined technique is proposed.
