Driven by the difficulty of meeting clean energy goals and by surging electricity demands, a growing number of political leaders are taking a fresh look at nuclear power — both extending the life of existing reactors and building new ones.

Even past skeptics, largely Democrats, have come around to the idea — notably in California, where the state’s sole remaining nuclear plant, Diablo Canyon, is scheduled to close in 2025. The search for clean energy has given nuclear power a spark that has drawn bipartisan support that added billions in funding for existing and new projects…

In addition to the $6 billion fund, the administration is providing $2.5 billion for two projects meant to demonstrate new nuclear technology, in Washington State and Wyoming.

A separate bipartisan measure introduced last year is aimed at preserving and expanding nuclear energy in the United States. The bill, whose backers include Senators Shelley Moore Capito, Republican of West Virginia, and Cory Booker, Democrat of New Jersey, would provide financial assistance like tax credits, according to the Tax Foundation, a nonprofit tax policy organization.
