The U.S. Coast Guard is seeking public comments on a proposal that would allow barges to transport shale gas wastewater. The wastewater is a byproduct of the drilling process, and it can include both man-made chemicals and naturally occurring heavy metals and radiation.
The European Commission's energy chief says the bloc's executive arm will present a proposal on mandatory disaster insurance for nuclear power plants in coming weeks.
A reactor that was shut down for refueling Sept. 30 at the Beaver Valley Nuclear Power Station in western Pennsylvania has been restarted and is expected to reach full capacity in the next week.
"Just as the tragic event had global consequences, the success of the cleanup also has global significance. So we all have a direct interest in seeing that the next steps are taken well and efficiently and safely," said U.S. Energy Secretary Ernest Moniz at a lecture in Tokyo.
Japanese regulators have given final approval for the removal of fuel rods from an uncontained cooling pool at a damaged reactor building, which is considered the highest risk at the crippled Fukushima nuclear plant. Removing the fuel rods from the Unit 4 cooling pool is the first major step in a decommissioning process that is expected to last decades.
Human mistakes are mostly to blame for the recent mishaps, as workers deal with a string of crises. A top Japanese regulator feels these "silly mistakes" are a sign of declining morale. TEPCO acknowledged a systemic problem in a recent report, saying workers under tight deadlines tend to cut corners, and others don't fully understand their assignments or procedures.
The Three Mile Island nuclear power plant is shut down while more than 1,700 technical workers perform inspections, upgrade equipment and do maintenance that cannot be done while the plant is operating. One-third of the plant's radioactive fuel will be replaced, new digital equipment will be installed and the turbines that produce electricity will be overhauled.
Greenland's parliament has agreed to remove a 25-year-old ban on uranium mining, paving the way for an industrial boom that the Arctic island hopes will help it gain independence from former colonial master Denmark.
A nuclear power plant in Oconee County, South Carolina had to shut down one of its three reactors after a problem was detected in the water system that helps generate electricity to run the turbines.
Ten mishaps in just eight months at the crippled Fukushima nuclear power plant are raising doubts about the operator's ability to tackle the crisis and prompting concern that another disaster could be in the making. Even more troubling, a typhoon is forcasted to hit the area this weekend.
A panel that advises Vermont state policymakers on activities at the Vermont Yankee nuclear power plant on Wednesday passed a resolution urging prompt dismantlement after the reactor closes next year. Entergy, the owning company, has not said how long the process should take, but federal Nuclear Regulatory Commission rules indicate it can take up to 60 years.
Dressed in white hazmat coveralls and carrying a dosimeter, documentary film director Robert Stone ventured into the damaged Fukushima nuclear plant's exclusion zone a year after a massive earthquake and tsunami triggered meltdowns in three reactors. As he encountered abandoned homes, shops and toppled cars in the scene in his new film "Pandora's Promise," Stone asked a traveling companion, "So, are you still pro-nuclear?"
A conference in Pittsburgh focuses on putting a stop to coal mining, fracking for oil and gas and nuclear power, but organizers also want workers to join the battle against climate change. Union leaders say that workers need new jobs to make a transition to clean energy, noting that shutting down industries such as coal can turn entire communities into a ghost town.
Rainwater has overflowed concrete barriers surrounding 12 clusters of tanks storing radiation-contaminated water at the crippled Fukushima Daiichi nuclear power plant. TEPCO said it cannot rule out the possibility that contaminated water has reached the Pacific Ocean as a result. Additionally, due to stalled clean-up efforts, some residents of nearby towns will have to wait years before returning.
Florida utility regulators approved a multi-billion-dollar settlement with the state's second largest utility that will require customers to keep paying for shuttered and abandoned nuclear power plants. While some had called the deal with Duke Energy a "rip-off," those who voted in favor of the settlement called it a way to bring an end to a lengthy and complex process.
The Florida Power Service Commission could approve a settlement which calls for Duke Energy Florida utility customers to keep paying for shuttered nuclear plants for the next several years. The decision follows nearly a day's worth of testimony from Duke Energy officials as well as some members of the public and lawyers representing utility customers. Duke has nearly two million customers in the Sunshine State.
The number of safety violations vary, according to a congressional study awaiting release. Lower-level violations pose very low risk, such as improper upkeep of a transformer, while higher-level violations range in significance, such as an electrical system that caused a fire.
Three years after the U.S. government promised $8.3 billion in lending for a nuclear plant in Georgia, Southern Company and its partners have not sealed a deal. President Barack Obama's administration recently agreed to a fourth extension of the deadline for finalizing lending agreements.
The head of the U.N. nuclear agency urged Japan to work harder to address international concerns about leaks of contaminated water at its crippled Fukushima nuclear plant, and said his agency will jointly monitor radiation levels in the nearby ocean. International Atomic Energy Agency chief Yukiya Amano told Japan's top nuclear regulator that it is crucial that the country share data with the international community.
Six workers at Japan's crippled nuclear power plant have been accidentally doused with highly radioactive water, the plant operator said, adding to a growing list of mishaps that are shaking confidence in the utility's ability to handle the crisis. The workers reportedly removed the wrong pipe from equipment.
The Nuclear Regulatory Commission is being asked to restrict storage of highly radioactive nuclear waste in spent fuel pools like the one at the Entergy Corp.'s Vermont Yankee nuclear plant. The commission heard recently from two authors of a 2003 report saying densely packed fuel pools create a heightened danger of fire and a catastrophic release of radioactivity.
Design changes at a new radioactive waste disposal plant at the country's most contaminated nuclear site in south-central Washington were not properly verified to ensure safety, the U.S. Department of Energy's Inspector General concluded. The audit was highly critical of the design change process at the Hanford Nuclear Reservation's $12.2 billion vitrification plant.
The operator of the meltdown-plagued Fukushima Dai-ichi nuclear plant says at least 110 gallons spilled when workers overfilled a storage tank without a gauge that could have warned them of the danger. The error is one of many the operator has committed as it struggles to manage a seemingly endless, tainted flow of contaminated water.
It wasn't a tsunami, but it had the same effect: A huge cluster of jellyfish forced one of the world's largest nuclear reactors to shut down — a phenomenon that marine biologists say could become more common. Operators of the Oskarshamn nuclear plant in southeastern Sweden had to scramble after tons of jellyfish clogged pipes that bring cool water into the plant's turbines.
Industry minister Toshimitsu Motegi on Monday suggested he supports local calls to scrap the Fukushima Daini nuclear power plant, located near the accident-stricken Fukushima Daiichi complex. The Daini complex is located 12 kilometers south of the Daiichi plant and achieved a stable state of cold shutdown shortly after the natural disasters in 2011.
