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.

Growing and sustaining a nuclear team
How do you grow a nuclear team? At Duke Energy, we do it by being reliable, innovative, and forward looking. Since 1967, we’ve been growing our nuclear generation to produce life-essential, carbon-free electricity for millions of customers in our communities. Safe, reliable, cost-effective nuclear generation.
Nuclear generation is an essential component of Duke Energy’s overall climate strategy, with the goal of net-zero carbon emissions from electric generation by midcentury. Net zero is achieved when greenhouse gas emissions are counterbalanced and removed from the atmosphere, achieving “climate neutrality.” Duke’s nuclear fleet produces more than 50 percent of the electricity consumed by our Carolinas customers and more than 80 percent of the carbon-free electricity generated company-wide. In 2021, our nuclear fleet matched its record capacity factor of 95.7 percent and avoided the release of 50 million tons of carbon dioxide.

As part of the ongoing international DECOVALEX project, four research teams used five different models to simulate coupled thermal, hydrological, and mechanical (THM) processes near waste emplacement drifts of geological nuclear waste repositories. The simulations were conducted for two generic repository types, one with open and the other with back-filled repository drifts, under higher and lower postclosure temperatures, respectively. In the completed first model inception phase of the project, a good agreement was achieved between the research teams in calculating THM responses for both repository types, although some disagreement in hydrological responses is currently being resolved. In particular, good agreement in the basic thermal-mechanical responses was achieved for both repository types, even though some teams used relatively simplified thermal-elastic heat-conduction models that neglected complex near-field thermal-hydrological processes. The good agreement between the complex and simplified process models indicates that the basic thermal-mechanical responses can be predicted with a relatively high confidence level.
