In the last few months, nuclear startups have raised huge amounts of money – well done $1 billion until now.

Data centers and their thirst for electricity have become a driving force. But recent changes in federal nuclear safety policies could be another acceleration that could help clear the way for rapid reactor development at a potential cost to human health and the environment.

The Trump administration is quietly changing how the Department of Energy oversees the safety and security of nuclear power plants built on its properties, according to a report from NPR. About a third of the rulebook was deleted, and several sections were significantly revised. Previous requirements, including those aimed at limiting groundwater and environmental contamination, are now proposals, and workers may be exposed to higher doses of radiation. Plant security protocols are now in place at the company.

The new rules were made without public comment or notice, according to NPR. This applies only to reactors built on DOE property; those established elsewhere are still under the supervision of the Nuclear Regulatory Commission. Several startups are developing demonstration reactors on DOE property in hopes of meeting the Trump administration’s July 4, 2026 deadline.
