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.

Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

Bench scale methane cracking tests have been completed using a stack of ten SAES® St909 pellets. Baseline test conditions were five percent methane in helium at ten seem, 101 kPa (760 torr), and 700°C. Changes from baseline conditions varied temperature, pressure, flow rate, and carrier gas composition to include hydrogen and nitrogen. Methane cracking efficiency (ɛM) decreased with decreasing temperature and pressure. Faster gas feed rates decreased ɛM, but cracked more methane. Introducing hydrogen, nitrogen, or ammonia into the feed gas reduced ɛM, but ammonia was still cracked at high efficiencies. ɛM was further decreased when both nitrogen and hydrogen were in the carrier gas compared to using a carrier of only nitrogen or hydrogen.
