Last week, Korean Electric Power (KEPCO) connected its second advanced pressure reactor (APR) 1400 nuclear reactor to the grid. This is significant because these power plants, with a generation capacity of 1,400 megawatts (MW), would be able to generate about as much electricity as the combined output of all the wind facilities in Minnesota, for a fraction of the cost.
Nuclear power plants are incredibly efficient, with capacity factors of 90 percent or higher. This means nuclear plants will generate about 90 percent of their theoretical output during the course of a year. As a result, building just one APR1400 reactor...
