Nationwide production climbed 0.6 percent to 82,867 megawatts, or 81 percent of capacity, the most since March 14, according to U.S. Nuclear Regulatory Commission data compiled by Bloomberg. Output was 6.2 percent higher than a year ago with 18 of 104 reactors offline.
TVA’s 1,104-megawatt Browns Ferry 2 reactor, about 84 miles (135 kilometers) north of Birmingham, Alabama, advanced to 47 percent of capacity from 16 percent yesterday. The unit shut March 14 for refueling and maintenance.
Browns Ferry led output higher by 0.7 percent to 26,938 megawatts in the Southeast, while Prairie Island raised Midwestern generation by 0.6 percent to 16,662 megawatts.
Reactor maintenance shutdowns, usually undertaken in the U.S. spring or fall when energy use is lowest, may increase consumption of natural gas and coal to generate electricity. The average refueling down time was 46 days in 2012, according to the Nuclear Energy Institute.
