Heightened oversight follows safety concerns at Limerick Generating Station

    The Nuclear Regulatory Commission will increase oversight and inspections at the Limerick Generating Station following concerns over “inadequate procedures related to the operation of two main feedwater system valves.”

    A failure of two safety systems in the spring led to the month-long shut-down of Unit 2’s Reactor Core Isolation Cooling. The issue could have increased the safety risks at the plant should an accident have occurred during that time.

    As the Mercury reports, Exelon declined to provide and appeal response to NRC’s findings, and has already informed the commission of the corrective measures taken. Additional inspections will be scheduled.
