The corporate media silence on Fukushima has been deafening . . .

Ever more radioactive water continues to pour into the Pacific. . .

Hundreds more tons are backed up on site, with Tepco apologists advocating they be dumped directly into the ocean without decontamination.

TOKYO — The government of Prime Minister Shinzo Abe made its biggest push yet to revive Japan’s nuclear energy program on Tuesday, announcing details of a draft plan that designates atomic power as an important long-term electricity source.

The new Basic Energy Plan, which states that Japan will push to restart reactors that were closed after the disaster in 2011 at the Fukushima Daiichi nuclear power plant, overturns a promise made by a previous government to phase out the country’s nuclear reactors. The plan also leaves open the possibility of building new plants as well as restarting existing ones.

The International Atomic Energy Agency (IAEA) handed Japan the final report from an expert mission that reviewed remediation efforts in areas affected by the Fukushima Daiichi accident.

The IAEA report, which is available online, describes the findings of the Follow-up IAEA International Mission on Remediation of Large Contaminated Areas Off-Site the Fukushima Daiichi Nuclear Power Plant, held on 14 to 21 October 2013. The report highlights important progress in all areas to date, and offers advice on several points where the team feels it is still possible to further improve current practices.

TOKYO — It was the part of the Fukushima Daiichi nuclear power plant that spooked American officials the most, as the complex spiraled out of control two and a half years ago: the spent fuel pool at Reactor No. 4, with more than 1,500 radioactive fuel assemblies left exposed when a hydrogen explosion blew the roof off the building.

In the next 10 days, the plant’s operator, the Tokyo Electric Power Company, is set to start the delicate and risky task of using a crane to remove the fuel assemblies from the pool, a critical step in a long decommissioning process that has already had serious setbacks.

Just 36 men will carry out the tense operation to move the fuel to safer storage; they will work in groups of six in two-hour shifts throughout the day for months.

The tsunami that wrecked the Fukushima Daiichi power plant has led to the toughest nuclear cleanup ever. Radioactive water is still poisoning the sea – and it could take 40 years to fix the mess. Is Japan up to the challenge?

theguardian.com - by Ian Sample - December 3, 2013

Carefully, gently, one-by-one. The removal of nuclear fuel rod assemblies from a badly damaged building at the Fukushima Daiichi power plant is finally under way. Months in the planning, the job is risky, complex, and crucial. Here begins the first major step in the toughest decommissioning project ever attempted.

Prime Minister Shinzo Abe said Sunday that Japan is open to receiving overseas help to contain widening disaster at the crippled nuclear plant in Fukushima, where radioactive water leaks and other mishaps are now reported almost daily.

"We are wide open to receive the most advanced knowledge from overseas to contain the problem," Abe said in his English speech to open the conference on energy and environment at an international science forum in Kyoto in western Japan.

"My country needs your knowledge and expertise," he said.

Double whammy feared; Izu braces for the worst

Less than a week after being hit by the largest typhoon in a decade, Tokyo is bracing for another strong storm that will likely reach the area Saturday, and it may get merged with an even stronger approaching tempest.

Though less powerful than Typhoon Wipha, incoming tropical cyclone Francisco is rated as “strong,” the Meteorological Agency said. But on a possible collision course is Typhoon Lekima, considered “more fierce.”

Weather Channel, Oct. 18, 2013 at 9:45p ET: Super Typhoon Francisco Brushes Guam, Could Threaten Japan Next Week [...] A tropical cyclone is dubbed a “super typhoon” when maximum sustained winds reach at least 150 mph – the equivalent of a Category 4 hurricane on the Saffir-Simpson scale. [...] Conditions appear favorable for development [... allowing] the typhoon to strengthen in intensity, possibly to 160 mph (Category 5 status) over the next few hours. After that, Francisco will move into a region of cooler ocean temperatures, which cause the typhoon to weaken. Francisco may threaten southern Japan early next week, however the current forecast from the Joint Typhoon Warning Center indicates that the typhoon will be much weaker by that point. That said, intensity forecasts at five days out in time can be highly uncertain [...]

The first removal of nuclear fuel rods next month from the stricken Fukushima atomic station should be successful based on findings that the rods -- each about twice the average weight of a sumo wrestler -- appear undamaged from an explosion at the site almost three years ago.

That’s the view of Lake Barrett, a former U.S. Nuclear Regulatory Commission official appointed last month as an adviser to Tokyo Electric Power Co. (9501), the operator of the wrecked Fukushima Dai-Ichi nuclear plant.

21 October 2013 | Tokyo -- The International Atomic Energy Agency (IAEA)'s international expert mission to review remediation efforts in areas affected by the Fukushima Daiichi accident concluded today with the presentation of a Preliminary Summary Report to Japan's Senior Vice-Minister of the Environment, Shinji Inoue.

The Follow-up IAEA International Mission on Remediation of Large Contaminated Areas Off-site the Fukushima Daiichi NPS recognised the huge effort and enormous resources that Japan is devoting to its remediation strategies and activities, with the aim of improving living conditions for people affected by the nuclear accident and enabling evacuees to return home.

The Mission Team highlighted important progress since the first IAEA remediation mission in October 2011, noted that Japan had made good use of advice from that earlier Mission, and offered fresh advice in a number of areas where it is still possible to further improve current practices, taking into account both international standards and the experience of remediation programmes in other countries.

The latest leakage at the crippled Fukushima Daiichi nuclear plant comes from a different, more contaminated water source and raises new questions about TEPCO's ability to manage the crisis.

nationalgeographic.com - by Patrick J. Kiger - August 21, 2013

In the latest crisis to strike the Fukushima-Daiichi nuclear power plant in Japan, operator Tokyo Electric Power (TEPCO) has discovered that 300 tons (nearly 72,000 gallons) of highly radioactive water has leaked from a holding tank into the ground over the past month.

(Reuters) - Highly radioactive water seeping into the ocean from Japan's crippled Fukushima nuclear plant is creating an "emergency" that the operator is struggling to contain, an official from the country's nuclear watchdog said on Monday.

This contaminated groundwater has breached an underground barrier, is rising toward the surface and is exceeding legal limits of radioactive discharge, Shinji Kinjo, head of a Nuclear Regulatory Authority (NRA) task force, told Reuters.

Countermeasures planned by Tokyo Electric Power Co are only a temporary solution, he said.

Tepco's "sense of crisis is weak," Kinjo said. "This is why you can't just leave it up to Tepco alone" to grapple with the ongoing disaster.

"Right now, we have an emergency," he said.

A new material for protecting nuclear fuel could cut down on the risk of explosions like the one at the Fukushima Daiichi nuclear power plant.

Traditionally, a zirconium alloy cladding is used to encase the uranium fuel rods; however, this alloy, when heated past design specifications, splits water molecules to produce hydrogen gas.

M.I.T. researchers have come up with a new cladding made out of silicon carbide which would hopefully drastically reduce the risk of hydrogen explosions at nuclear power plants.

TOKYO -- Japan's nuclear watchdog says the crippled Fukushima plant is likely leaking contaminated water into sea, a problem long suspected by experts.

Watchdog commissioners instructed operator Tokyo Electric Power Co. on Wednesday to find where the water may be leaking from.

The plant was ravaged by the March 2011 earthquake and tsunami and has since struggled with leaks of water used to cool the reactors, hampering decommissioning efforts.
