SUPPLEMENTARY INFORMATION: Section 208 of the Energy Reorganization
Act of 1974, as amended (Pub. L. 93-438), defines an ``abnormal
occurrence'' as an unscheduled incident or event that the NRC
determines to be significant from the standpoint of public health or
safety. The FY 2025 AO Report, NUREG-0090, Volume 48, ``Report to
Congress on Abnormal Occurrences: Fiscal Year 2025,'' describes those
events that the NRC identified as AOs during FY 2025.
This report describes seven events involving Agreement State
licensees and two events involving NRC licensees. Four AOs were medical
events, as
[[Page 36160]]
defined in part 35 of title 10 of the Code of Federal Regulations,
``Medical Use of Byproduct Material.'' The remaining five AOs consisted
of one loss of an industrial radiography source, two events involving
overexposure of declared pregnant radiation workers, one significant
breakdown in radiological controls, and one unintended fetal/embryo
exposure during a medical procedure. No events at commercial nuclear
power plants met the AO criteria.
The NRC identified no events at NRC-licensed facilities during FY
2025 that met the guidelines for inclusion in Appendix B, ``Other
Events of Interest.''
One event met the guidelines for inclusion in Appendix C, ``Updates
on Previously Reported Abnormal Occurrences.''
Agreement States are those States that have entered into formal
agreements with the NRC pursuant to section 274 of the Atomic Energy
Act of 1954, as amended (AEA), to regulate certain quantities of AEA
material at facilities located within their borders.
The Federal Reports Elimination and Sunset Act of 1995 (Pub. L.
104-66) requires that AOs be reported to Congress annually. The full
report, NUREG-0090, Volume 48, ``Report to Congress on Abnormal
Occurrences: Fiscal Year 2025,'' is also available electronically at
the NRC's public website at <a href="https://www.nrc.gov/reading-rm/doc-collections/nuregs/staff">https://www.nrc.gov/reading-rm/doc-collections/nuregs/staff</a>.
Authority: 42 U.S.C. 2011 et seq.

Secretary of the Commission.
