The NRC’s Office of Investigations recently published its Annual Report for Fiscal Year (FY) 2025, summarizing its activities from October 1, 2024 through September 30, 2025. In FY 2025, OI opened 90 cases, a 9% increase from FY 2024. But OI also increased the number of case closures, closing 98 cases in FY 2025––a 20% increase from FY 2024. While investigations into alleged discrimination (i.e., alleged retaliation against nuclear whistleblowers) increased, the number of such investigations remained well below prepandemic levels. Further, an overall trend of increasing investigations of materials licensees continued into 2025.
