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.

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.
The operator of Japan's wrecked Fukushima nuclear power plant said Tuesday it is struggling to stop contaminated underground water from leaking into the sea. Tokyo Electric Power Co. said some of the water is seeping over or around an underground barrier it created by injecting chemicals into the soil that solidified into a wall.
Mitsubishi Heavy Industries Ltd. will fight Southern California Edison's allegations of gross negligence in the design and manufacture of steam tubes built for the San Onofre nuclear power plant, which has been permanently shut down due to excessive wear in the tubes.
The powerful earthquake that rocked Japan in 2011 set off tremors around a West Texas oil field, according to new research that suggests oil and gas drilling operations may make fault zones sensitive to shock waves from distant big quakes.
Officials from the Nuclear Regulation Authority said a leak is "strongly suspected" and urged plant operator Tokyo Electric Power Co. to determine where the water may be leaking from and assess the environmental and other risks, including the impact on the food chain.
Japan moved a step closer to restarting nuclear reactors Monday as four utility companies applied for safety inspections of 10 idled plants, the clearest sign of a return to atomic energy nearly two and a half years after the Fukushima disaster.
Japan's nuclear watchdog has formally approved new safety requirements for atomic plants, paving the way for the reopening of facilities shut down since the Fukushima disaster. The new requirements approved Wednesday by the Nuclear Regulation Authority will take effect on July 8, when operators will be able to apply for inspections.
Plant chief Takeshi Takahashi told journalists given a tour of the plant Wednesday that workers have cleaned up much of the debris in their work areas, but that the priorities are keeping the plant stable and working toward shutting it down — a process that operator Tokyo Electric Power Co. estimates will take 40 years.
Keeping the meltdown-stricken Fukushima nuclear plant in northeastern Japan in stable condition requires a cast of thousands. Increasingly the plant's operator is struggling to find enough workers, a trend that many expect to worsen and hamper progress in the decades-long effort to safely decommission it.
It was the first time Japanese regulators had officially recognized an active fault underneath an existing reactor, virtually acknowledging that the risk at Tsuruga had been overlooked for decades by both the operator and regulators despite warnings by some experts.
The Nuclear Regulation Authority's decision is the latest blow to the Monju fast-breeder reactor and Japan's nuclear fuel cycle program. The government of Prime Minister Shinzo Abe is hoping that Monju will be a key part of Japan's plans for disposing of atomic waste and reducing the nation's plutonium stockpile.
A Japanese court has rejected a demand that a city affected by the fallout of the country's 2011 nuclear disaster evacuate its children. The unusual lawsuit was filed on behalf of the children by their parents and anti-nuclear activists in June 2011. The Sendai High Court handed down its ruling Wednesday.
The government and plant operator Tokyo Electric Power Co. have predicted the cleanup would take up to 40 years. They still have to develop technology and equipment that can operate under fatally high radiation levels to locate and remove melted fuel. The reactors must be kept cool and the plant must stay safe and stable.
The U.N.'s nuclear watchdog agency Monday began reviewing the decommissioning process at Japan's crippled nuclear plant, where new problems are triggering growing safety concerns about a cleanup expected to take decades. The experts will assess and analyze melted reactors, radiation levels and waste management at the Fukushima Dai-ichi plant to make its decommissioning process safer and more stable.
The investigators told parliament on Monday that the recently formed Nuclear Regulation Authority is merely rubber-stamping TEPCO's work at the plant, which is still using makeshift equipment put together after the March 2011 disaster, caused by a massive earthquake and tsunami in northeastern Japan.
The plan is meant to encourage more innovation and modernization of the power grid as the country grapples with its energy policy following the shut-downs of almost all its nuclear power plants after the March 2011 tsunami disaster at the Fukushima Dai-Ichi plant.
