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.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

Temperature dependence of oxide layer formation on hydrogen isotope retention in stainless steel type 316 was studied by TDS and XPS. The shape of TDS spectrum was clearly changed by the oxide formation temperature. The chemical states of iron, chromium and oxygen were also evaluated by XPS. The surface oxide layer was composed of iron and oxygen and the contribution of chromium was quite low. The ratio of oxide layer on stainless steel increased as increasing the annealing temperature. The deuterium retention trapped by the oxide layer, which corresponded to the desorption temperature of 600-800 K, was governed by the ratio of oxide layer, especially iron hydroxide. All of the iron was not oxidized and the saturation ratio of iron oxide to pure iron existed in the stainless steel. It was concluded that the saturation of deuterium retention trapped by the oxide layer was controlled by the amount of iron oxide in the oxide layer.
