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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

The atmospheric dispersion model (Tritium-EESAD) was further modified so as to be able to predict tritium concentration in plant tissue free water (TFWT), organically-bound tritium (OBT) and groundwater. The modified model was validated by participating in the Pine Tree Scenario of the IAEA EMRAS program. Monitoring data were disclosed after submission of model predictions and compared with them. Overall time trends of the predicted tritium concentrations in almost all calculation endpoints agreed well with those of observations within a factor of two.
