The PWR reactor at the Fort Calhoun nuclear power plant in Nebraska will shut down for good on October 24th, 2016. The reactor first went online in September, 1973 and was the smallest nuclear reactor in the United States in terms of power generation (476 MW). The Nuclear Regulatory Commission received a letter from Omaha Public Power District (OPPD) that notified them of the utilities decision to decommission the lone reactor at the power plant.
In June, the OPPD announced that it had reached a decision to shut down the plant, but an exact date had not been announced. The utility estimated that it would save $1 billion over the next 20 years if it decommissioned the power plant.
The plant was the focus of international concern after the Missouri River flooded and surrounded the facility with rising water. The reactor was forced to remain offline for nearly three years while OPPD responded to a wide range of deficiencies identified in inspections by the NRC after the flooding event.
