A U.S. science advisory report says a key lesson from Japan's Fukushima nuclear accident is that the nation's nuclear industry needs to focus more on the highly unlikely but super-serious worst case scenarios.

Researchers are trying to develop tougher types of fuel that might reduce the damage during extreme events like the one at the Fukushima Dai-ichi nuclear plant.
The operator of the crippled Fukushima Daiichi nuclear power plant began construction of a huge underground ice wall around four reactor buildings, a key measure to tackle the toxic water buildup at the complex.
A former worker is seeking 11 million yen ($110,000) in compensation from the operator of Japan's Fukushima nuclear plant for exposing him to high levels of radiation after the 2011 tsunami.
Experts on Friday expressed skepticism about a plan to build a costly underground frozen wall at Japan's crippled nuclear plant, a development that could delay the start of construction on the project.
Around 1.1 tons of radioactive water overflowed Wednesday from a container during cleansing of a water treatment system at the crippled Fukushima Daiichi nuclear power complex, plant operator Tokyo Electric Power Co. said.
Tatsuta said "1F" is not about taking sides on the debate over nuclear power, but simply a story of what it's like to work there.
Three years later, nearly 270,000 people remain displaced from their homes, including many from Fukushima prefecture who may never be able to return home due to radioactive contamination.
Eyeing dozens of aging reactors at home and hundreds of others worldwide, Japanese industry sees a profitable market for decommissioning expertise.
The draft presented Tuesday to the Cabinet for approval expected in March, said Japan's nuclear energy dependency will be reduced as much as possible, but that reactors meeting new safety standards set after the 2011 nuclear crisis should be restarted.
Highly radioactive water has overflowed from a storage tank at Japan's crippled nuclear power plant, but the operator says it did not reach the Pacific Ocean. The operator, Tokyo Electric Power Co., said Thursday that the leak involved partially treated water from early in the crisis, meaning it was more toxic than previous leaks.
The plaintiffs said that manufacturers — Toshiba, GE and Hitachi — failed to make needed safety improvements to the 4-decade-old reactors at the Fukushima plant. They are seeking compensation of $1 each, saying the idea is to raise awareness of the problem.
Officials on the Industry Ministry's contaminated water panel also said that the Fukushima Dai-ichi plant could run out of storage for contaminated water within two years if current plans are not fully workable. A draft report, made available to reporters after the panel's experts and officials met, proposed covering the ground with asphalt to reduce rain inflow, building giant tanks and other steps.
Nobody knows exactly how much fuel melted after the March 2011 earthquake and tsunami knocked out cooling systems. Or where exactly the fuel went — how deep and in what form it is, somewhere at the bottom of reactor Units 1, 2 and 3.
The wind farm near the Fukushima Dai-Ichi nuclear power plant is to eventually have a generation capacity of 1 gigawatt from 143 turbines, though its significance is not limited to the energy it will produce.
When tons of radioactive water leaked from a storage tank at Fukushima's crippled nuclear power plant and other containers hurriedly put up by the operator encountered problems, Yoshitatsu Uechi was not surprised. He wonders if one of the tanks he built will be next.
U.S. Energy Secretary Ernest Moniz said he expects deepening cooperation with Japan over the high-stakes cleaning up and decommissioning of the crippled Fukushima nuclear plant.The Fukushima plant has had a series of mishaps in recent months, including radioactive water leaks from storage tanks.
The head of the U.N. nuclear agency says Japan should work harder to address international concerns about leaks of contaminated water at its crippled Fukushima nuclear plant and that his agency will jointly monitor radiation levels in the nearby ocean.
Tokyo Electric Power Co. said that a pump to inject water into one of the severely damaged reactors at the Fukushima Daiichi nuclear power plant halted Monday, possibly due to a problem at a power switchboard. The halt occurred at around 9:47 a.m. But cooling of the No. 1 reactor immediately resumed through a backup pump, the utility known as TEPCO said.
Another day, another radioactive-water spill. The operator of the meltdown-plagued Fukushima Dai-ichi nuclear plant says at least 430 liters (110 gallons) spilled when workers overfilled a storage tank without a gauge that could have warned them of the danger.
Many in this city, where the world's first atomic-bomb attack killed tens of thousands, are distressed by efforts to connect their suffering to the tsunami-triggered meltdowns at the Fukushima Dai-ichi nuclear plant.
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 Japanese news agency Kyodo News reported that the plant's operator, Tokyo Electric Power Co., observed no abnormality in radiation or equipment after the quake.
Japanese Prime Minister Shinzo Abe ordered the operator of the country's crippled nuclear power plant Thursday to scrap all six reactors at the site instead of just four already slated for decommissioning and to concentrate on tackling pressing issues like radioactive water leaks.
Nuclear Regulation Authority Chairman Shunichi Tanaka said Thursday that Tokyo Electric Power Co.'s use of data regarding contamination levels of storage tank leaks at its Fukushima plant were inaccurate and exaggerated risks. He suggested dispatching advisers to train workers how to properly handle equipment and data.
The Japanese government announced Tuesday that it will spend $470 million on a subterranean ice wall and other steps in a desperate bid to stop leaks of radioactive water from the crippled Fukushima nuclear station after repeated failures by the plant's operator.
The operator of Japan's tsunami-crippled nuclear power plant said Tuesday that about 300 tons (300,000 liters, 80,000 gallons) of highly radioactive water have leaked from one of the hundreds of storage tanks there — its worst leak yet from such a vessel.
