Performance Improvement Nuclear power plants in the United States have continued to improve their performance steadily over the past decade.  In 2007, according to industry data, these plants achived a record-low production cost of 1.68 cents per kilowatt hour and a record-high level of electricity production.  This is a result of many high-performing nuclear fleets that have evolved since deregulation in 1997.  What has helped maintain and improve industry results has been the performance improvement (PI) process.
