The domestic nuclear fleet’s average estimated capacity factor in October 2016 was 80.9%, compared to 82.5% in October 2015, according to information from the Nuclear Energy Institute (NEI).
Estimated U.S. nuclear generation in October 2016 was 60.3 billion kWh, compared to 60.6 billion kWh in October 2015, according to NEI’s monthly nuclear performance report.
Twenty-one reactors were shut down for refueling for some or all of October.
Industry highlights during October included the start of commercial operations at the Tennessee Valley Authority (TVA) Watts Bar 2 facility. Watts Bar 2 is a 1,100-MW Westinghouse four-loop pressurized water reactor (PWR).
Also during October, the Omaha Public Power District (OPPD) Fort Calhoun nuclear plant shut down, NEI noted. The smallest commercial nuclear plant in the nation 478-MW, Fort Calhoun ceased operations on Oct. 24. Its fuel was removed during the period between Oct. 29 and Nov. 7, according to NEI.
Year-to-date the domestic nuclear power industry has recorded a capacity factor of 91.1%. That’s below the 2015 YTD figure of 92.7% but slightly better than the 91% recorded during the same period in 2014, NEI report.
Generation estimates are based on Nuclear Regulatory Commission (NRC) monthly operating reports obtained through the Institute of Nuclear Power Operations (INPO) and Energy Information Administration (EIA) 923 Form, according to NEI.
Capacity figures come from the EIA and are the net summer capacities reported in the 860 Form; other capacity figures are from media or company reports, NEI said.
