Gavin Newsom, second from right, during discussion about a renewing the plant's license on June 28, 2016, in Sacramento, Calif. California's last operating nuclear power plant could get a second lease on life. Owner Pacific Gas & Electric decided six years ago to close the twin-domed power plant by 2025. But Democratic Gov. Newsom, who was involved in the agreement to close the reactors, has prompted PG&E to consider seeking a longer lifespan for the plant. (AP Photo/Rich Pedroncelli, File)
