A Nebraska environmental group is questioning the track record of the company hired to run the Fort Calhoun nuclear power plant because of concerns federal regulators have raised.
The Clean Nebraska group said Monday that questions the Nuclear Regulatory Commission has raised about some of the calculations Exelon made for its other nuclear plants were troubling.
The NRC said it was looking into whether Chicago-based Exelon intentionally understated the cost of decommissioning many of its nuclear plants.
Exelon spokesman David Tillman said the company denies intentionally providing incorrect data.
Tillman said that the calculations were complicated and Exelon looked forward to meeting with the NRC.
The Omaha Public Power District hired Exelon last year because of its experience and safe track record. Fort Calhoun has been idle since 2011.
