The water comes from the Fukushima Daiichi nuclear power plant. Although most scientists agree it does not pose an immediate environmental threat, some are worried about the long-term consequences.

Local fishermen and the government of neighboring China are among the critics of Japan's decision to release water from the crippled Fukushima nuclear plant into the Pacific Ocean.

The Nuclear Ship Savannah offers a snapshot of a nuclear future that never quite came to pass.

The Zaporizhzhia Nuclear Power Plant used a large reservoir for cooling water. Now that reservoir is rapidly draining.

Public pressure, stoked by disasters at Three Mile Island, Chernobyl and Fukushima, put pressure on successive German governments to end their use. Germany began winding down the plants Saturday.

The 400,000 gallon leak of water containing tritium occurred in November 2022, but the general public was not notified until last week. Officials said the leak is contained and poses no public danger.

The Zaporizhzhia Nuclear Power Station was among the Ukrainian structures damaged by a barrage of Russian missiles on Wednesday. Though power has been restored, the threat of nuclear meltdown remains.

Japan adopted a plan to extend the lifespan of nuclear reactors, replace the old and even build new ones, a major shift in a country scarred by the Fukushima disaster.

A giant laser facility in Livermore, Calif., says it has created net energy from nuclear fusion. It's an important breakthrough, but fusion power remains a distant dream.

Citing climate change and the need to cut carbon emissions, California is extending the life of the Diablo Canyon nuclear power plant.

The international atomic watchdog has been to some of the world's toughest locations, but nothing quite like Europe's largest nuclear power plant in an active war zone.

Environmentalists advocating for nuclear power have led a push to extend the operating life of Diablo Canyon, California's last nuclear power plant. Japan and Germany consider similar extensions.

Satellite images and social media analyzed by NPR show attacks have hit structures around the plant, coming dangerously close to causing a nuclear disaster.

Federal regulators say a nuclear power plant being built in Georgia can begin loading radioactive fuel into one of its two new reactors. It's a key step toward generating electricity at the first new nuclear reactor built in decades in the United States.

Investment from the government and private sector are changing the trajectory of the aging U.S. nuclear fleet and spurring development of new nuclear technology.
