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.

U.S. nuclear capacity factors: Ideal for data centers?
Baseload nuclear generation doesn’t get the respect it deserves, if you ask nuclear operators. But the hyperscale data centers that process our digital lives—like the one right next to the Susquehanna plant in northeastern Pennsylvania—are pushing electricity demand up. Clean, reliable capacity now looks a lot more valuable.

Measurements of high-energy neutrons through shield penetration and maze streaming were performed at the Conseil Européen pour la Recherche Nucléaire (CERN) High-energy Accelerator Mixed-Field (CHARM) facility. The protons of 24 GeV/c were injected onto a 50-cm-thick copper target and the released neutrons were transmitted through shields and a maze in the facility. The transmitted neutrons in the shield and maze were measured using activation detectors placed behind various materials and thicknesses of the shields and at several locations in the maze. From the radionuclide production rates in the activation detectors, the attenuation profiles though the shield thickness and along the maze were obtained for the reactions of 209Bi(n,xn)210-xBi(x = 4–9), 27Al(n,α)24Na, 115In(n,n’)115mIn, and 12C(n,2n)11C. Monte Carlo simulations were performed with three codes, PHITS, FLUKA, and GEANT, which had good agreement with the measurements within a factor of 2 for the production rates.
