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.

This paper presents the final design and main manufacturing aspects of the RFX Magnetizing Winding, now being manufactured by ABB. The winding is designed to store 15 Wb flux and consists of 200 copper turns wound into 40 coils. These are impregnated in groups to form 17 blocks, to satisfy mechanical requirements. The largest coils, with diameters exceeding 8 m, are demountable into two halves, for ease of transport and assembly. The peak turn current is 50 kA and the peak voltage per turn is 700 V. A special connection between the coils allows the resulting voltage across the terminals of each sector to be kept below 35 kV and the voltage to earth below 17.5 kV. To limit diffusion phenomena inside the solid conductors, the innermost 24 coils are wound with two conductors connected in parallel at the coil terminals, transposed with each other at the half coil. Polymide and glass tapes impregnated with epoxy resin provide good insulation without excessive thickness.
