The Nuclear Regulatory Commission staff will hold a virtual public meeting June 1 to discuss the
2022 safety performance of the Byron and Braidwood nuclear power plants. Both two-unit plants are based
in Illinois and are operated by Constellation Energy Generation.
The online meeting will be held from 5-6 p.m. Central time and can be accessed via Microsoft
Teams or by phone. The telephone conference number is 301-576-2978, passcode 924411735#. The NRC
staff responsible for plant inspection and oversight, including the resident inspectors based full-time at the
sites, will make a presentation and answer questions from the public at the meeting.
The NRC determined that Byron and Braidwood plants operated safely during 2022. All inspection
findings and performance indicators for both plants were green, or of very low safety significance. As a
result, Byron and Braidwood remain under NRC’s normal level of oversight, which entails thousands of
hours of inspection each year.
The NRC Reactor Oversight Process uses color-coded inspection findings and indicators to assess
plant performance. The colors start at green and increase to white, yellow or red, commensurate with the
safety significance of the issues involved. If an inspection finding or performance indicator has more than
very low safety significance, the NRC increases its oversight.
Inspections are performed by two NRC resident inspectors assigned to each plant and specialist
inspectors from the Region III Office in Lisle, Illinois.
The annual assessment letters for Byron and Braidwood are available on the NRC website. Current
performance information for the plants is also available and updated on a quarterly basis.
