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.

Release curve of bred tritium from various ceramic breeder materials such as Li2ZrO3, Li2TiO3, and Li4SiO4 were obtained using the out-pile temperature programmed desorption method in the Kyoto University Research Reactor. A 0.4g sample of breeder particles contained in a quartz tube was irradiated for 120s at the thermal neutron flux of about 2.8x1017n/m2s in N2 atmosphere under the temperature of 360K. Tritium release behavior was measured using an ionization chamber connected to the release tritium measurement apparatus. The sample was purged by dry N2, N2 with hydrogen of various partial pressure, or humidified N2 gas. The temperature of the sample bed was changed linearly from room temperature to 1073K with the rising rate of 5K/min.Characteristics of tritium release behavior obtained for various ceramic breeder materials under various purge gas conditions are compared in this paper.
