Scientists Warn of Security Risks with New Uranium Fuel for US Nuclear Reactors

High-assay low-enriched uranium could be directly used in nuclear weapons, raising proliferation concerns

HALEU is enriched up to 20%, compared to the 5% used in most current reactors.
The Biden administration supports HALEU for its potential to reduce emissions and combat climate change.
Experts argue that without strict regulations, HALEU could blur the line between civilian and military nuclear programs.
The US plans to produce over 40 metric tonnes of HALEU by the end of the decade.
Companies like TerraPower are developing reactors that will use HALEU, despite delays due to supply shortages.
