The U.S. Nuclear Regulatory Commission (NRC) receives reports from its licensees under Part 21 of Title 10 of the Code of Federal Regulations. This regulation specifies the conditions under which information must be submitted when a licensed facility, activity, or basic component fails to comply with the Atomic Energy Act of 1954, as amended, or other NRC regulations.
As of November 27, 2018, a web page listing 50.73 Licensee Event Reports that may report Defects and Noncompliance (in lieu of Part 21) is being provided for information purposes only. It is important to note that the information contained in these Licensee Event Reports is provided by the licensee, and has not been verified by the NRC to actually constitute a defect as described in 10 CFR Part 21. The NRC initially introduced the practice of linking Licensee Event Reports that may report Defects and Noncompliance to the Part 21 Reports page of the NRC public website in Information Notice 2011-19 "Licensee Event Reports Containing Information Pertaining to Defects to Basic Components."
