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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.

A major challenge in nuclear fusion research is the coherent combination of measurements from heterogeneous diagnostics. Different measurement techniques for measuring the same subset of physical parameters provide complementary and redundant data for, e.g., improving the reliability of physical parameters, increasing the spatial and temporal resolution of profiles, and resolving data inconsistencies.The concept of integrated data analysis within the framework of Bayesian probability theory was applied to the combined analysis of lithium beam emission spectroscopy (LIB), deuterium cyanide laser interferometry, electron cyclotron emission (ECE), and Thomson scattering spectroscopy. The four heterogeneous diagnostics enable the simultaneous estimation of electron density and temperature profiles with high spatial and temporal resolution. The coherent analysis of the profile diagnostics allows one to consider diagnostic interdependencies correlating density and temperature profiles, e.g., ECE shine-through, and diagnostics alignment. The benefits of a combined analysis of diagnostics will be shown in a modular way by successively increasing the set of diagnostics starting with the LIB diagnostics.
