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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.
18th International Probabilistic Safety Assessment and Analysis (PSA 2023)

Alexander J. Huning
The risk from accidents and hazards at a nuclear facility can be quantified by using established probabilistic safety assessment (PSA) techniques. This panel aims to discuss 1) If, how, and why these techniques or analogues are, can be, or should be used in risk informed security analysis, 2) Benefits of incorporating the analysis in the design of a facility or reactor, and 3) How probabilistic safety and security analysis are, can be, or should be working together to inform design. Included in this discussion, panelists will address the new and evolving security analysis techniques for the existing fleet to reduce costs and provide improved protection, and how advanced and small modular reactors will integrate security analysis at an earlier stage to build and operate the next generation of nuclear power plants more efficiently. This panel will bring together panelists from a broad spectrum to discuss security by design, safety analysis vs. security analysis, and the 2S (safety and security) by design framework. The panel session will comprise of panelist statements (brief), roundtable discussions, and audience Q&A (time permitting). The focus will be on dynamic interactions instead of presentations.
