The Nuclear Regulatory Commission(NRC) said it will increase oversight at the single-unit, 900 MW Harris nuclear power plant in North Carolina due to violations linked to the ventilation systems for emergency facilities at the plant. The plant is owned by Progress Energy Carolinas, a subsidiary of Duke Energy (NYSE: DUK).
The NRC said one violation involves the company’s failure to maintain the Emergency Operations Facility (EOF) ventilation system, which was out of service for extended periods over two years.
The company was also cited for not notifying the NRC during the times that the ventilation system was degraded or out of service.
The NRC determined that the violation involving the EOF ventilation system has low to moderate safety significance.
