Another unplanned outage at Mississippi’s Grand Gulf nuclear power plant is adding to regulators’ concerns over reliability problems at the largest single-unit nuclear power plant in the United States. The move is also heightening scrutiny over whether problems at Entergy Corp.’s plant may be affecting power markets.
Operators took the southwest Mississippi plant offline last week, citing problems with a turbine bypass valve. Last Wednesday’s outage came to light Tuesday when the federal Nuclear Regulatory Commission announced a special inspection.
“The reactor was safely shut down but some equipment issues occurred that the agency wants to better understand,” the agency said in a statement.
It’s at least the sixth unplanned decrease in output at the plant in the last 15 months, according to NRC documents. The plant has been running at reduced or zero power output for much of the time since 2016, according to an analysis published earlier this month by E&E News .
