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.

The busyness of the nuclear fuel supply chain
Ken Petersenpresident@ans.org
With all that is happening in the industry these days, the nuclear fuel supply chain is still a hot topic. The Russian assault in Ukraine continues to upend the “where” and “how” of attaining nuclear fuel—and it has also motivated U.S. legislators to act.
Two years into the Russian war with Ukraine, things are different. The Inflation Reduction Act was passed in 2022, authorizing $700 million in funding to support production of high-assay low-enriched uranium in the United States. Meanwhile, the Department of Energy this January issued a $500 million request for proposals to stimulate new HALEU production. The Emergency National Security Supplemental Appropriations Act of 2024 includes $2.7 billion in funding for new uranium enrichment production. This funding was diverted from the Civil Nuclear Credits program and will only be released if there is a ban on importing Russian uranium into the United States—which could happen by the time this column is published, as legislation that bans Russian uranium has passed the House as of this writing and is headed for the Senate. Also being considered is legislation that would sanction Russian uranium. Alternatively, the Biden-Harris administration may choose to ban Russian uranium without legislation in order to obtain access to the $2.7 billion in funding.

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.
