The U.S. Senate overwhelmingly passed a major bipartisan bill aimed at revitalizing the country’s nuclear energy sector, with an 88-2 vote. Only Senators Ed Markey and Bernie Sanders opposed it.

The legislation, paired with a reauthorization of firefighter grant programs, now heads to the president’s desk.

It seeks to accelerate the approval of new nuclear plants, reduce licensing fees, and streamline environmental reviews. Supporters say it’s vital for energy security and emissions reduction, while critics warn it could weaken nuclear safety oversight.

The U.S. currently operates 93 nuclear reactors, generating about 20% of the nation’s electricity. Advocates say nuclear energy plays a key role in combating climate change, but concerns about waste storage and regulatory rollbacks remain part of the ongoing debate.
