Nuclear Regulatory Commission staff will discuss the 2023 safety performance of the
Millstone nuclear power plant during a meeting with the Connecticut Nuclear Energy Advisory
Council May 16. The two-unit plant, operated by Dominion Nuclear, is in Waterford, Connecticut.
The meeting will be held at the Waterford Town Hall, 15 Rope Ferry Road, beginning at
7 p.m. NRC staff responsible for plant inspections, including the resident inspectors based full-time
at the site, will deliver a short presentation on the NRC’s assessment of the plant’s performance,
followed by a question-and-answer session.
Millstone Units 2 and 3 operated safely during 2023. At the end of the year, all inspection
findings and performance indicators were green, or of very low safety significance. As a result, both
units remain under the 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
measure plant performance. The colors start at green and increase to white, yellow or red,
commensurate with the safety significance of the issues involved. Inspection findings or
performance indicators with more than very low safety significance trigger increased NRC
oversight.
Inspections are performed by three NRC resident inspectors and special inspectors from the
Region I office in King of Prussia, Pennsylvania.
The annual assessment letter for Millstone and the meeting notice are available on the NRC
website. Current performance information for Unit 2 and Unit 3 is also available and is updated
quarterly.
