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.

To reduce the defective coating fraction of TRISO-coated UO2 particles, failure mechanisms of fuel particle coating during the coating processes have been studied. Examinations of the coated fuel particles at every coating stage revealed two kinds of silicon carbide (SiC)-defective particles. The SiC-defective particles with partly carbonized kernels were formed by chemical reactions during SiC deposition when the coating layer of inner dense pyrolytic carbon was defective. The SiC-defective particles with nonreacted kernels were formed by mechanical shocks during unloading of SiC-coated particles from the coater. The coating processes were improved by controlling particle fluidization modes in the coater and by adopting a coating process without unloading and loading of the particles at intermediate coating stages.
