NEW YORK, April 29 (Reuters) - U.S. electric utility Entergy ETR.N is looking to expand its nuclear power output by upgrading its existing plants, while it considers advanced nuclear technologies in its territory across the U.S. South, company executives said on Tuesday.

U.S. nuclear power, which is virtually carbon free, has been in high demand in recent years, particularly from growing electricity use from Big Tech with climate-drive energy pledges.
