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.

Reboot: Nuclear needs a success . . . anywhere
The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.
Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?
As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?

The sorption of americium(III) and neptunium(V) on some major minerals of igneous rocks (quartz, microcline, albite, bytownite, biotite, hornblende, augite, olivine, and kaolinite) and on two granites has been studied, the aqueous phase being on artificial groundwater and with pH varying from four to nine. The sorption was measured on crushed solids (0.044 to 0.063 mm) at ambient temperature by a batch technique, using 241 Am (2 × 10−9M) and 235Np (2 × 10−11 M). For both americium and neptunium, sorption isotherms were obtained that seem to be related to the formation of hydrolyzed species of the elements in the aqueous phase, giving an increased sorption with an increase of the degree of hydrolysis (starting at pH 5 for americium and at pH 8 for neptunium). The sorption on the individual minerals seems to be qualitatively related to their specific surfaces (and cation exchange capacities), but the differences between high-sorbing biotite and low-sorbing quartz were not more than one order of magnitude (in terms of distribution coefficients) in the studied pH range. Distribution coefficients for the granites were equal to the weighted average values of the distribution coefficients for the individual minerals within a factor of three.
