The reactor pressure vessel was removed in May 2007 and shipped to Chem-Nuclear's Barnwell, South Carolina low-level radioactive waste (LLRW) disposal facility.

In 2012, spent nuclear fuel from the reactor was sealed into a dry cask storage installation located immediately south of the Genoa Generating Station.

[4] Spent reactor fuel continues to be stored on site pending the creation of a national radioactive waste disposal facility such as Yucca Mountain.

[6] In February 2017, workers spilled about 400 gallons of radioactive wastewater into the Mississippi River after leaving a hose and sump pump in a tank overnight.

[7] The wastewater contained Caesium-137 at concentrations greater than allowed under federal regulation for discharge; however, the resulting radiation was below levels considered harmful to human health.
