ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

National awards to be presented at ANS Winter Conference
One of the few constants at American Nuclear Society national meetings is the recognition of exceptional individuals in the nuclear community. ANS President Lisa Marshall has named this season’s award recipients, who will receive recognition at the upcoming Winter Conference and Expo in Orlando, Fla.
ANS also announces the winners of awards presented by the Society’s professional divisions. These awards will be mailed to the recipients, and the divisions will recognize honorees at various division functions and meetings this fall. The 19 professional divisions of ANS are constituent units and represent a vast array of nuclear science and technology disciplines.

This presentation describes some experiments to investigate the removal, regrowth and evolution of tritium from stainless steel planchets that had been exposed to elemental tritium. The total tritium sorbed onto and into a planchet was measured by heating the planchet and collecting the evolved tritium. The removable surface activity was determined from swipe measurements. The evolution of tritium from the planchets was determined by leaving some of the planchets exposed to air for almost one year and then measuring the tritium remaining. The swipe experiments indicate that a removal efficiency of 10% is representative but usually conservative for an undisturbed surface. In general, the fraction of activity that is removable is dependent on the surface history. If a cleaned surface is left undisturbed for a few days removable surface activity may regrow. If the surface is left undisturbed for a long period of time (months) some of the tritium in the planchet will be lost to the atmosphere.
