Lusby, MD – Nuclear Regulatory Commission staff will discuss the 2018 safety performance of the Calvert Cliffs nuclear power plant, operated by Exelon, during an open house on April 30 in Prince Frederick.

The open house, to be held at the SpringHill Suites Hotel, 75 Sherry Lane, Prince Frederick, will run from 6-7 p.m. NRC employees responsible for plant inspections, including the resident inspectors based full-time at the site, will be available to discuss the plant’s performance.

Calvert Cliffs operated safely during 2018. At the end of the year, all inspection findings and performance indicators were no greater than green, or of very low safety significance. As a result, the plant remains 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 two NRC resident inspectors and inspection specialists from the agency’s Region I Office.

The annual assessment letter for Calvert Cliffs, as well as the notice for the open house, are available on the NRC website. Current performance information for Unit 1 and Unit 2 is also available.
