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 Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

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.

Several types of diagnostic system for soft X-ray radiation (SXR) have been developed and installed on the Large Helical Device (LHD). Magnetohydrodynamic (MHD) activities are studied by the fluctuation component of SXR, and the electron temperature is measured from the spectrum of the SXR. PIN photodiode arrays are installed at three poloidal cross sections to study the equilibrium and fluctuations. The spatial resolution of an array is a few centimeters, and its frequency response is up to [approximately]300 kHz. Absolute extreme ultraviolet diode arrays are also used for lower-energy radiation, and edge MHD instabilities are thereby studied. There are tangentially viewing two-dimensional soft X-ray camera systems by which more detailed spatial structure can be studied. Radial profile of X-ray spectrum is measured by X-ray pulse height analyzer systems.
