Nuclear Safety at Risk: What’s Changing Under Donald Trump

Key Takeaways

• DOE cut 750 pages of nuclear safety rules, weakening protections.
• New SMR pilot allows reactors without NEPA review or full NRC oversight.
• Worker radiation exposure limits doubled, delaying investigations of incidents.
• Data‑center AI demand drives rush to approve risky nuclear projects.
• Past cost overruns like Vogtle show deregulation can raise, not lower, expenses.

Pulse Analysis

The Trump administration’s aggressive deregulatory agenda has reached the nuclear sector with a sweeping revision of Department of Energy safety directives. In January, more than 750 pages of rules were removed, eliminating explicit requirements to protect groundwater, wildlife and surrounding ecosystems from radioactive releases. The new language merely urges agencies to “consider” such impacts, while the threshold for triggering worker‑radiation investigations was doubled. By erasing detailed barrier specifications and lowering environmental safeguards, the overhaul creates regulatory gaps that could expose communities to higher radiological risk.

The changes are tied to a pilot program for small modular reactors (SMRs), which the DOE hopes to have three units operating by July 4. Unlike traditional plants, these reactors—about the size of a city block and under 300 MW—are exempt from the National Environmental Policy Act, meaning no public comment or environmental review is required. The push is fueled by the exploding electricity demand of AI data centers, which now consume over 4 % of U.S. power and could reach 17 % by 2030. Industry giants and tech billionaires are lobbying for faster approvals, raising concerns that safety shortcuts are being taken to satisfy energy‑hungry algorithms.

History shows that lax oversight rarely translates into cost savings. Georgia’s Vogtle reactors, completed after seven‑year delays, ran $23 billion over the original $14 billion estimate, underscoring how construction errors and regulatory shortcuts can inflate expenses. Moreover, the reduced safety margins of SMRs may generate more radioactive waste per megawatt than larger plants, complicating long‑term disposal. While nuclear power can contribute to decarbonization, the current deregulation risks undermining public trust and could backfire economically, suggesting that a measured, transparent regulatory framework remains essential for sustainable energy development.
