Environmentalists trying to defeat what could be Utah's first nuclear power plant went to court Monday to challenge a water-rights transfer for the project. A judge opened the weeklong trial that focuses on a decision by state Engineer Kent Jones to let a company take 53,000 acre-feet of water a year from the Green River to cool nuclear reactors.
A former U.S. nuclear regulatory chief, Gregory Jaczko, said Tuesday that leaks of contaminated water at the crippled Fukushima plant had been known since early in the crisis and have worsened because Japan acted too slowly. Jaczko said he was surprised how long it took Japan to start tackling the problem.
Federal regulators announced Monday they are considering slapping a California utility with two violations for problems that eventually led to the permanent closure of the San Onofre nuclear power plant. The Nuclear Regulatory Commission said in a report that Southern California Edison failed to identify a flawed design for four replacement steam generators.
A planned outage at a South Carolina nuclear plant will cost about $60 million, according to officials. The scheduled outage this week at Duke Energy's H.B. Robinson nuclear power plant includes refueling the reactor and other maintenance tasks.
A 5.3-magnitude earthquake has hit the Japanese prefecture that is home to the nuclear power plant crippled in the March 2011 earthquake and tsunami. The U.S. Geological Survey says the quake struck early Friday at a depth of about 13 miles under Fukushima and about 110 miles northeast of Tokyo.
Japanese Prime Minister Shinzo Abe ordered the operator of the country's crippled nuclear power plant to scrap all six reactors at the site instead of just the four already slated for decommissioning. He also told TEPCO officials to concentrate on tackling pressing issues like radioactive water leaks.
A senior official from Tokyo Electric Power Company, which runs Japan's troubled nuclear power plant in Fukushima, recently told reporters that the safety situation at the facility was "not under control," though the company quickly released a statement saying otherwise.
Susquehanna nuclear power plant operators said Sunday that they found a water leak in one of its units. The plant, located in Luzerne County near Berwick, Pa., is owned jointly by PPL Susquehanna LLC and Allegheny Electric Cooperative Inc.
Japan is once again without atomic energy as its only operating nuclear reactor went offline Sunday for refueling and maintenance, and other plants remain closed for intensified safety checks following the 2011 meltdowns at the tsunami-stricken plant in Fukushima.
Lake Barrett, a former U.S. nuclear regulator, says cleaning up Tokyo Electric Power Co.'s wrecked Fukushima plant is a bigger challenge than the work he led at Three Mile Island and that ongoing radioactive water leaks are a minor part of that task.
Virtually every major project under the National Nuclear Security Administration's oversight is behind schedule and over budget — the result, watchdogs and government auditors say, of years of lax accountability and nearly automatic annual budget increases for the agency responsible for maintaining the nation's nuclear stockpile.
Japan lodged a protest Thursday against a French newspaper cartoon depicting sumo wrestlers with extra limbs fighting in front of the country's crippled nuclear power plant and linking it to Tokyo's successful bid to host the 2020 Olympics.
The power utility that co-owns San Onofre, the recently shuttered nuclear plant, is asking the California Public Utilities Commission to let it recover its investments by collecting more than $800 million from customers. Regulators are evaluating the request.
Federal regulators say the Cooper nuclear power plant continues to operate safely and doesn't need additional oversight. The Nuclear Regulatory Commission issued a mid-year performance update for Cooper and all the nation's nuclear power plants on Thursday.
South Korea announced Friday that it was banning all fish imports from along Japan's northeastern coast because of what officials called growing public worry over radioactive water leaking into the Pacific Ocean near the crippled Fukushima Dai-ichi nuclear power plant.
New revelations of contaminated water leaking from storage tanks at the tsunami-ravaged Fukushima Dai-ichi nuclear power plant have raised alarm, coming just weeks after Japanese officials acknowledged that radioactive water has been seeping into the Pacific from the plant for more than two years,
Japan's nuclear regulator said Thursday that it is largely unknown what impact radioactive water leaking from the country's wrecked nuclear plant is having on the Pacific Ocean and the situation must be monitored more closely.
The idle Fort Calhoun nuclear power plant is loaded with fuel for the first time in more than two years, and utility officials say it will operate safely if regulators allow it to restart. But the Nuclear Regulatory Commission says they haven't decided whether to allow the plant to restart.
For the last 2 ½ years, fishermen from the port of Yotsukura near the stricken Fukushima Dai-Ichi nuclear plant have been mostly stuck on land with little to do but catch fish for radiation testing. There is no commercial fishing along most of the Fukushima coast.
Japan's nuclear regulator on Wednesday upgraded the rating of a leak of radiation-contaminated water from a tank at its tsunami-wrecked nuclear plant to a "serious incident" on an international scale, and it castigated the plant operator for failing to catch the problem earlier.
The announcement that the Vermont Yankee nuclear plant is closing is bringing cheers from nuclear critics and anguish from the plant's defenders, while already a new fight is brewing over how long its owners should be given to dismantle the reactor.
The Mississippi Energy Institute is pushing for more exploration of storing and reprocessing used nuclear fuel in the state at the same time that one of the its congressmen is coming out against it. Leaders of the institute, which promotes energy development, pitched ideas Monday to the state Senate Economic Development Committee.
A nuclear reactor in southern New Jersey resumed operations Saturday after crews repaired a leak in the containment building that was discovered two days earlier. Regulators say the spill was confined to the containment building, and there was never a threat to the public or workers.
Japan's industry minister pledged urgent government action Monday to curb leaks of radioactive water from the crippled Fukushima Dai-Ichi nuclear plant. He said lax maintenance by the plant's operator was largely to blame for the series of leaks from storage tanks at the plant.
Deep beneath Fukushima's crippled nuclear power station a massive underground reservoir of contaminated water that began spilling from the plant's reactors after the 2011 earthquake and tsunami has been creeping slowly toward the sea.
