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.

Candidates for leadership provide statements: ANS Board of Directors
With the annual ANS election right around the corner, American Nuclear Society members will be going to the polls to vote for a vice president/president-elect, treasurer, and members-at-large for the Board of Directors. In January, Nuclear News published statements from candidates for vice president/president-elect and treasurer. This month, we are featuring statements from each nominee for the Board of Directors.

This paper examines the neutron-energy spectra of sodium-cooled fast reactors, with primary attention given to the neutron-energy range from 30 keV to 10 MeV, the major source of irradiation damage in a fast reactor. The status of relevant fast neutron cross-section knowledge is examined, and the influence of cross-section uncertainties is included in the comparison of theoretical predictions with experiment. Also examined, are differences among various theoretical methods and problems in determining the spectrum in real systems with interfaces and heterogeneities. The current status of studies of the EBR-II flux and spectrum is summarized, including determination of absolute flux magnitude and two-dimensional estimates of the considerable influence of neighboring subassemblies and experimental heterogeneity on the very high energy spectrum. Finally, the relationship between flux monitor data, knowledge of spectra, and radiation damage is discussed.
