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.

Uncertainty contributes to lowest uranium spot prices in 18 months
A combination of plentiful supply and uncertain demand resulted in spot pricing for uranium closing out March below $64 per pound, with dips down to about $63.50 during mid-March—the lowest futures prices in 18 months, according to tracking by analysis firm Trading Economics. Spot prices have also fallen steadily since the beginning of 2024. Meanwhile, long-term prices have held steady at about $80 per pound at the end of March, according to Canadian front-end uranium mining, milling, and conversion company Cameco.

The diagnosis of plasma-facing components in a fusion environment is challenging due to the limited number of measurement techniques that have been developed for in situ surface analysis. In this work, we assess the feasibility of using neutron reflectometry (NR) for the in situ diagnosis of deuterium accumulation in tungsten and dispersion-strengthened tungsten alloys. TRIM is used to simulate deuterium implantation at different energies to approximate the deuterium depth profiles in these materials in order to calculate the expected measurements from NR for various fluences. Our results suggest that NR should be an effective technique for testing hypotheses about the surface composition of materials under fusion-relevant fluences of deuterium irradiation.
