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.

The operation of fusion reactors requires the development of a 6Li enrichment process that does not have a negative impact on the environment. This study focuses on a new two-liquid-phase chemical exchange system, liquid-metal/chloride molten salt system. In this system, 6Li is distributed unevenly between immiscible liquid metal and chloride molten salt. After two-liquid contacting mixing, a quadrupole inductively coupled plasma spectrometry measurement was performed. The measured isotope ratio of 6Li to 7Li was corrected with mass bias compensation, and separation factor α was obtained. In both systems (Li/LiCl-KCl system, and Li-Pb/LiCl-KCl system), the α values were greater than 1 at 648 K almost at a 68% confidence interval, showing that more 6Li was likely distributed to liquid metal than to chloride molten salt. These results suggest that this system is applicable to enrich 6Li under optimal temperature conditions.
