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.

NWTRB to hold public meeting on SNF disposal and corrosion
The Nuclear Waste Technical Review Board, an independent federal agency that evaluates the Department of Energy’s efforts to manage and dispose of spent nuclear fuel and high-level radioactive waste, will hold a two-day public meeting May 21–22 to review information on the DOE’s research and development activities related to the disposal of SNF and HLW in crystalline host rocks and on the corrosion of commercial SNF after disposal.

A new method for determining the angular and energy distributions of an anisotropic fast-neutron flux by using nuclear emulsions based on the proton-recoil method is proposed. The relation between the distributions of neutron flux and proton-recoil tracks is analyzed, and formulas for obtaining the angular distribution and energy spectrum of the neutron flux from the measurement of proton-recoil tracks are derived. Measurements were made to investigate the accuracy of this method with the emulsion plate, which was irradiated inside a natural uranium system. The experimental results show that the measurement of the anisotropic component, which hitherto could not be measured, is possible.
