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.

Information is provided on the self-ignition temperature (SIT) of blown bitumen asphalt mixed with sodium nitrate and some chemicals that are added in the bituminization process to adjust pH and to immobilize the radioactive isotopes of Cs, Sr, and I. In each ignition temperature test, the prepared bitumen sample was heated at a constant rate of temperature increase, and the ignition point was measured. Among the tested chemicals added to the bitumen, Ni(NO3)2 shows a relatively large SIT decrease, and furthermore, the mixture of Ni(NO3)2 and AgNO3 has been shown to greatly lower the SIT of blown bitumen. It is suggested that, in general, segregation of these nitrates should be avoided in bituminization, and care should be taken in handling Ag in a Purex reprocessing plant from the viewpoint of waste treatment. Furthermore, the oxidation effects of Fe(NO3)3 were tested by measuring torque of the bitumen sample. It was confirmed that the addition of Fe(NO3)3 to bitumen rapidly oxidizes the bitumen and increases the viscosity of the bitumen mixture.
