iaea.org - January 24, 2014

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.

Removing Fuel Rods Poses New Risks at Crippled Nuclear Plant in Japan

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.

Fukushima Two Years On: a Dirty Job With No End in Sight

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.

Typhoon Francisco on Course for Japan — May Follow Typhoon Wipha’s Path … Developed in a Similar Area (VIDEO)

enenews.com - Energy News - October 19, 2013

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 [...]

Three Mile Island Veteran Optimistic on Fukushima Fuel Removal

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.

IAEA Expert Remediation Mission to Japan Issues Preliminary Report

                                          

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.

Latest Radioactive Leak at Fukushima: How Is It Different?

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.

Fukushima Reactor Water Level Shallower Than Thought

yomiuri.co.jp - March 28, 2012

The water level in the containment vessel of the No. 2 reactor at the Fukushima No. 1 nuclear power plant is only about 60 centimeters deep, far shallower than previously assumed levels of about four meters, according to Tokyo Electric Power Co.

The lower-than-expected water level was discovered for the first time when the power utility used an industrial endoscope to check the crippled reactor's interior on Monday, TEPCO said.

According to some experts, it is possible that nuclear fuel that melted through the reactor's pressure vessel and accumulated on the bottom of the containment vessel in the aftermath of the March 11 earthquake and tsunami may not be completely covered in the water.

TEPCO said the water temperature in the vessel remained relatively low within a range of 48.5 C to 50 C. The discovery of the unexpectedly shallow water level will not affect TEPCO's judgment that the reactor is in a state of "cold shutdown."

Japan Questions Earthquake Forecasts

submitted by Samuel Bendett

Homeland Security News Wire - March 2, 2012

Following the massive 11 March earthquake and tsunami that rocked Japan, residents and experts there have grown increasingly skeptical of quake forecasts.

Last month two University of Tokyo seismologists released a study that predicted a major earthquake would hit Japan’s capital city within the next four years. Their study was sharply criticized by those who said their claims were likely incorrect.

Bowing to pressure, the university’s Earthquake Research Institute posted a notice on its site that stated the latest earthquake forecast was the opinion of two researchers and noted the study’s “large margin of error.”

“Many seismologists think this kind of study is too simple,” said Naoyuki Kato, a seismologist at the institute, in an interview with the Washington Post.

Japan, which has been frequently rocked by powerful earthquakes in the past, invests more money than any other nation in the world on earthquake prediction, yet despite spending more than $100 million annually, the art of predicting earthquakes remains elusive.
