China goes all-in on home grown tech in push for nuclear dominance

China, the world's biggest energy consumer, was once seen as a "shop window" for big nuclear developers to show off new technologies, with Beijing embarking on a program to build plants based on designs from France, the United States, Russia and Canada. China signed a technology transfer deal with the United States in 2006 that put the AP1000 at the "core" of its atomic energy program. It also pledged to use advanced third-generation technology in its safety review after the 2011 Fukushima nuc...

Fukushima operator begins milestone task of removing nuclear fuel rods from damaged reactor

Operators of Japan’s nuclear power plant in Fukushima have started the milestone task of removing fuel from the first of three reactors that melted down during the 2011 disaster. The process is a critical step in the decades-long decommissioning process to ensure the plant is not vulnerable to further nuclear accidents if hit by another major quake and tsunami. It is the first time operators Tokyo Electric Power Co. have removed fuel from any of the three reactors that went into meltdown at Fuku...

Saudi Arabia close to building first nuclear reactor despite not signing up to international safeguards

Saudi Arabia plans to issue a multi-billion-dollar tender in 2020 to construct its first two nuclear power reactors and is discussing the project with US and other potential suppliers, three sources familiar with the plans have said. The world's top oil exporter wants to diversify its energy mix, adding nuclear power so it can free up more crude for export. But the plans are facing Washington's scrutiny because of potential military uses for the technology. Saudi Arabia, which aims to mi...

Fukushima contaminants found as far north as Alaska's Bering Strait

Radioactive contamination from Japan's Fukushima Daiichi nuclear power plant hit by a tsunami in 2011 has drifted as far north as waters off a remote Alaska island in the Bering Strait, scientists said on Wednesday. Analysis of seawater collected last year near St. Lawrence Island revealed a slight elevation in levels of radioactive cesium-137 attributable to the Fukushima disaster, the University of Alaska Fairbanks Sea Grant program said. "This is the northern edge of the plume," said Gay Sh...

The Three Mile Island nuclear accident 40 years ago

The 1979 accident at the Three Mile Island power plant, the worst in US history, claimed no lives but provoked an outcry over the country's nuclear electricity program. Caused by mechanical, design and human errors, the partial meltdown registered a five on the International Nuclear Event Scale that peaks at seven, the rate given to the Chernobyl (1989) and Fukushima (2011) disasters. Here is a rundown of what happened on March 28, 1979 at one of the two reactors at the Three Mile Island Gener...

UK, Japan scientists study radioactive Fukushima particles

Eight years after the Fukushima nuclear meltdown in Japan, radioactive particles collected from the site are undergoing new forensic investigation in Britain in an effort to understand the exact sequence of events. A 9.0 magnitude earthquake struck on March 11, 2011, off the Japanese coast, triggering a tsunami that killed some 18,000 people and the world's worst nuclear disaster since Chernobyl in 1986. Meltdowns at three of the Fukushima Daiichi plant's six reactors spewed radiation into the...

Eight years on, water woes threaten Fukushima cleanup

Last year, Tokyo Electric Power Co said a system meant to purify contaminated water had failed to remove dangerous radioactive contaminants. Workers could be seen atop the No. 3 building getting equipment ready to lift spent fuel rods out of a storage pool, a process that could start next month.

Fukushima evacuees resist return as 'Reconstruction Olympics' near

With Japan keen to flaunt Tokyo 2020 as the "Reconstruction Olympics", people who fled the Fukushima nuclear disaster are being urged to return home but not everyone is eager to go. Tokyo and the International Olympic Committee (IOC) plan to use the global spotlight from the Games to showcase the recovery of the region devastated by the 2011 nuclear disaster and the tsunami that triggered it, killing 18,000 people. Japan ordered more than 140,000 people to evacuate when the Fukushima Daiichi r...

Japan govt, Fukushima operator told to pay over nuclear disaster

A Japanese court Wednesday awarded nearly $4 million in fresh damages to scores of residents forced to flee their homes after the 2011 Fukushima nuclear meltdown. The Yokohama district court ordered the government and Tokyo Electric Power Co (TEPCO) to pay 419.6 million yen ($3.8 million) to 152 local residents, a court spokeswoman told AFP. The verdict was the fifth time the government has been ruled liable for the disaster in eastern Japan, the world's most serious nuclear accident since Che...

Results of mass screening of children, teens for thyroid cancer following Fukushima nuclear accident

The accident at Japan's Fukushima Daiichi nuclear power station in 2011 raised grave concerns about radioactive material released into the environment, including concerns over radiation-induced thyroid cancer. Ultrasound screenings for thyroid cancer were subsequently conducted in the Fukushima Health Management Survey. This observational study group includes about 324,000 people 18 or younger at the time of the accident and it reports on two rounds of ultrasound screening during the first five ...

Sweden calls for nuclear reactors to be shielded from hot weather

A number of Swedish reactors had to shut down or reduce output as the summer heatwave sent temperatures to record highs in July, with the sea water that is used to cool them becoming much warmer than normal, exceeding safety levels. The last time that SSM, the Swedish radiation safety authority, asked operators to produce plans to modify their reactors was after Japan's Fukushima disaster in 2011. The cost of post-Fukushima modifications to Swedish nuclear plants reached as much as 100 million...

Artificial intelligence accurately predicts distribution of radioactive fallout

Researchers at the University of Tokyo Institute of Industrial Science created a machine-learning-based tool that can predict where radioactive emissions from nuclear power plants will disperse. After training using extensive data on previous weather patterns, the tool consistently achieved over 85 percent predictive accuracy, and up to 95 percent in winter when large and predictable weather systems dominate. This tool can aid immediate evacuation in the aftermath of disasters like those at Fuku...

What was the fallout from Fukushima?

When a tsunami hit the nuclear plant, thousands fled. Many never returned – but has the radiation risk been exaggerated?Shunichi Yamashita knows a lot of about the health effects of radiation. But he is a pariah in his home country of Japan, because he insists on telling those evacuated after the 2011 Fukushima nuclear accident that the hazards are much less than they suppose. Could he be right?Yamashita was born in Nagasaki in 1952, seven years after the world’s second atomic weapon obliterated...

Court orders Japan government to pay new Fukushima damages

A Japanese court on Thursday ordered the government to pay one million dollars in new damages over the 2011 Fukushima nuclear disaster, ruling it should have predicted and avoided the meltdown. The Kyoto district court ordered the government and power plant operator Tokyo Electric Power Co (TEPCO) to pay 110 million yen in damages to 110 local residents who had to leave the Fukushima region, a court official and local media said. Thursday's verdict was the third time the government has been ru...

Fukushima operator aims to double visitors by Tokyo Olympics

Fukushima's nuclear power operator is hoping to double the number of visitors to its tsunami-ravaged facilities by 2020, seeking to use the Olympic spotlight to clean up the region's image. A massive undersea earthquake on March 11, 2011 sent a tsunami barrelling into Japan's northeast coast, leaving more than 18,000 people dead or missing and sparking the Fukushima crisis, the worst nuclear accident since Chernobyl in 1986. Initially, visitors to Fukushima Daiichi Nuclear Power plant were str...
