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.

Densification occurs during the aging of austenitic stainless steels. This study was conducted to determine the extent of densification during thermal aging of AISI Type 316 stainless steel. This objective was accomplished through both length change measurements and bulk density measurements on Type 316 stainless-steel tubing before and after aging treatments at 1200°F for aging times up to 1000 h. Various cold work levels, from 0 to 20%, were investigated. In all cases the tubes were found to shrink, the shrinkage increasing with cold-work level and aging time with a maximum change of −0.06% ΔL/L. A comparison of the bulk density and length change measurements indicates that within the experimental accuracy the densification phenomena are isotropic. Irradiation-induced creep and swelling in austenitic stainless steels have been a source of major concern in the development of LMFBRs. The densification or shrinkage phenomena influence measurements particularly for low values of strain and/or swelling. It is therefore important to take the densification phenomena into account when extrapolating low fluence data on swelling and creep.
