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.

Platinum and silicon have been found deposited on the palladium cathode during the electrolysis of a 0.1 M LiOD solution with a platinum anode in a glass cell. Various techniques including surface analysis, cyclic voltammetry, and electrochemical permeation were used to study the surface deposits, electrochemical deuterium-sorption behavior, and permeation rate of deuterium into palladium, respectively. It was shown that palladium cathodes were contaminated by platinum and silicon deposits after a certain period of electrolysis. These deposits could affect the electrochemical processes during electrolysis. The contamination may be a cause of the sporadic results reported in “cold fusion” research.
