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 2020 AO report, NUREG-0090, Volume 43, ``Report to 
Congress on Abnormal Occurrences: Fiscal Year 2020'' (ADAMS Accession 
No. ML21152A287), describes those events that the NRC identified as AOs 
during FY 2020.
    This report describes seven events in Agreement States and two 
events involving NRC licensees that were identified as AOs during 
FY2020. Eight AOs were medical events as defined in part 35 of title 10 
of the Code of Federal Regulations, ``Medical Use of Byproduct 
Material.'' There was one AO that was a human exposure event. The NRC 
did not identify any events at commercial nuclear power plants as AOs.
    The NRC identified four events during FY 2020 that met the 
guidelines for inclusion in Appendix B, ``Other Events of Interest.'' 
The first of these events was a human exposure event with possible 
internal contamination. The second event involved a gauge failure that 
resulted in unintended exposure to seven individuals, three of whom 
were classified as radiation workers who received occupational 
radiation exposure below regulatory limits. The third event was a stuck 
source event that resulted in an exposure above the regulatory annual 
limit to an individual involved in recovering the source. The fourth 
event concerned an extended loss of offsite power event at a commercial 
nuclear power plant. No events met the guidelines for inclusion in 
Appendix C, ``Updates of Previously Reported Abnormal Occurrences.''
    Agreement States are the 39 U.S. States that currently 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-licensed material at facilities located within their 
borders.
    The Federal Reports Elimination and Sunset Act of 1995 (Pub. L. 
104-68) requires that AOs be reported to Congress annually. The full 
report, NUREG-0090, Volume 43, ``Report to Congress on Abnormal 
Occurrences: Fiscal Year 2020,'' is also available electronically at 
the NRC's website at https://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/.

Secretary of the Commission.
