[4] They employ a combined number of 950 personnel at ANO[5] and generate enough power to meet approximately 56% of the total energy demand of Entergy Arkansas’ 700,000 customers.

[14] Its nuclear reactor and turbine generator were supplied by Combustion Engineering and General Electric, respectively.

[16] The Nuclear Regulatory Commission (NRC) defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 miles (16 km), concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 miles (80 km), concerned primarily with ingestion of food and liquid contaminated by radioactivity.

[17] The 2010 U.S. population within 10 miles (16 km) of Arkansas Nuclear One was 44,139, an increase of 17.2 percent in a decade, according to an analysis of U.S. Census data for msnbc.com.

Entergy also acknowledged that Unit One would be offline for an extended time while the company surveyed the damage and established a timeline for repairs.

[27] During the recovery from the incident a specialist engineering company named Lowther-Rolton [28] assisted with the recovery of the existing Stator and performed a "Technical Audit" (also called a "third-party review") of the engineering for lifting and installation of the new Stator to ensure safety of operations.

[30] In December 2016, it was disclosed that a certificate of conformity for Unit 2's steel reactor vessel closure head (RVCH), supplied by Creusot Forge, had been forged by the manufacturer, violating safety standards and potentially undermining the vessel head's mechanical ability to withstand sudden breakdown in certain conditions if excess carbon is present inside the steel.

[31] Per report ML18017A441 (February 22, 2018), the NRC Staff has determined issues related to the RVCH is negligible and warrants no immediate action.
