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.

The spatial and temporal evolution of the 3H levels in the water of the River Tagus in its passage through various regions of Spain and Portugal was analysed. Using mathematical time-series techniques, analytical expressions were obtained for the temporal trend and the periodicity present in the data.These expressions were used to determine the transit times between the sampling sites. The results indicated that the mean speed of 3H displacement was 12 km/month. The residence times of tritium in the water were also obtained. They were found to depend on the sampling points, with values ranging between 31 and 77 months. The concentrations of 3H varied cyclically at the six sampling points, with periods of around 24 months upstream of the Almaraz Nuclear Power Plant and about 12 months downstream.
