NRC asks for comments on FY 2026 fees proposal
The Nuclear Regulatory Commission is looking for feedback on its proposed rule for fees for fiscal year 2026, which begins October 1. The proposal was published in the March 12 Federal Register.
Based on the FY 2026 budget request because a full-year appropriation has not yet been enacted for the fiscal year, the proposed request is $971.5 million, an increase of $27.4 million from FY 2025.
