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 the Mining and Chemical Combine situated on the bank of the Yenisei River has resulted in intensive radioactive pollution of all components of the ecosystem by pollutants including tritium. Although tritium is considered to be little accumulated in bottom sediments and soils, it has been found that depending on the geochemical properties of soils tritium can be accumulated in some rocks due to binding with organic substances of the soil or penetrating into the layers of clay minerals and retaining in the interlayer space. Depending on the way of tritium inflow (water way or bottom sediments) it is distributed in plant parts non-uniformly. Here, in all the cases lamina dominates as the part of the plants most actively participating in photosynthesis. At constant tritium inflow to the Canada water weed biomass the intervention level for tritium was 2900 Bq/l.
