Japan Earthquake

Japan Earthquake | Page 2372

Just a small excerpt from venting at unit 3 (things were similarly scary at the other units) from NISA Sep. report to IAEA page II-104: "At 11:17 on March13, it was confirmed that the S/C vent valve (AO valve) large valve was closed again due to the pressure leak, a driving cylinder was replaced, and an opening operation was performed; at 12:30 on March 13, the S/C vent valve (AO valve) large valve was made open again.
When workers went to the spot (torus chamber) to maintain the S/C vent valve (AO valve) large valve in the open status for the purpose of preventing closure of the valve, it was so hot in the torus chamber, and also there was vibration due to the SRV operation that the valve was unable to maintain open.
At around 14:31 on March 13, the measurement results were reported of 300 mSv/h or higher on the north side of the reactor building double door (the inside was white and hazy), and 100 mSv/h on the south side. Also, at 15:28 on March 13, the dose in the Main Control Room of Unit 3 was 12 mSv/h, so that the people on duty evacuated to the side of the Main Control Room."

When the Tohoku earthquake and subsequent tsunami hit the Fukushima Daiichi Nuclear Power Station on March 11, 2011, the world witnessed the largest nuclear incident since the 1986 Chernobyl disaster. In a special Fukushima issue of the Bulletin of the Atomic Scientists, published by SAGE, experts examine the current and future impact of Fukushima, what might have been done to lessen the scale of the accident, and the steps we need to take both in Japan and worldwide to prevent another nuclear tragedy. www.sciencedaily.com

Fukushima crisis: Can Japan be at the forefront of an authentic paradigm shift? The catastrophe now referenced by a single word -- Fukushima -- is not merely a major natural disaster. The events of 3/11 sent shockwaves through the nuclear industry and governments around the world and constitute the end of a certain economic development model and the industrial risk calculation that underlies it. Giant, centralized electricity production sites that rain kilowatt-hours onto consumers who are constantly increasing their consumption -- while accepting risk that can potentially harm millions -- are now outdated. www.thebulletin.org

Pressure builds in Japan's nuclear divide. Following the disaster at the Fukushima Daiichi nuclear power plant six months ago, nine prominent Japanese intellectuals have launched a popular movement that seeks to abolish nuclear power and the closure of all nuclear power plants in Japan.

The group, which includes Nobel literature prize laureate Kenzaburo Oe and musician Ryuichi Sakamoto, plans to collect 10 million signatures in support of their proposal for a nuclear-free Japan. On Monday, the group organized a colorful demonstration followed by three vocal protest marches through Tokyo, attracting about 60,000 people. www.atimes.com

Japanese march against nuclear power . Chanting "sayonara nuclear power" and waving banners, tens of thousands of people have marched in central Tokyo demanding the Japanese government abandon atomic energy in the wake of the Fukushima nuclear accident.
The demonstration underscored how deeply a Japanese public long accustomed to nuclear power has been affected by the March 11 crisis, when a tsunami caused core meltdowns at three reactors at the Fukushima Dai-ichi complex.

@All hi! The video @Majj posted below tells the situation....Roke has increased strength to a typhoon and will cross the southern Japanese coastline in the next 24-30 hours bringing potentially devastating rains to the areas already hammered by Talas earlier this month. The system is expected to significantly weaken on crossing which should mean the strongest winds will only be along the southern coastline, TS strength(34-63kt) winds are still likely to be felt across much of Japan including at the Fukushima NPP, the system will begin extra tropical transtion after crossing pushing the higher wind boundary to the outer bands of the system albeit significantly weakended. The rain will be the problem again, recent microwave sat passes indicate significant potential for falls of 600mm+, precipitation this high should not be widespread and the eventual rainfall patern will depend greatly on the topography of the area of crossing-simply where the heaviest precipitation clouds are pushed into the high mountian ranges they will rain out the most. Kyushu will no doubt be hit hard again, models predict precipitation of 200mm+ for most of Japan(including the Fuku NPP) but only time will tell where the highest falls will occur. JMA have all manner of warnings out ahead of system as always and rain and wind can be monitored at the AMeDAS links(links can be found @ simplyinfo.org-weather resources ( houseoffoust.com )- cos Fukuifaq has disapeared if any one didn't notice? What happended there?) @Majj thanks for the video!:-)

TEPCO: groundwater may be flowing into plant

The Tokyo Electric Power Company, or TEPCO, says a large amount of groundwater may be entering the crippled Fukushima Daiichi nuclear power plant.

TEPCO says it has found that 200 to 500 tons of what is probably rainwater that seeped into soil may be entering daily through cracks in walls into the basements of buildings housing reactors and turbines.

The utility says it's worried that this will increase the amount of highly radioactive water in the basements.

Workers at the plant are injecting about 550 tons of water a day to cool 3 of its damaged reactors. About 80,000 tons of highly radioactive water has already accumulated in the buildings.

TEPCO says it plans to keep levels of radioactive water lower than those of groundwater to stop further inflows.

The government's Nuclear Safety Agency says groundwater inflow must be considered in drawing up a long-term decontamination plan.

Nuclear experts rethink their future

Japan's nuclear energy experts are discussing how complacency contributed to the accident at the country's Fukushima Daiichi power plant. They started a 4-day conference on Monday. It is their first major gathering since an earthquake and tsunami triggered a nuclear crisis.

The Atomic Energy Society of Japan meeting is happening in the southwestern city of Kitakyushu. The event was postponed after the March 11th disaster.

Participants include university professors, researchers and workers from the nuclear energy industry.

Professor Hisashi Ninokata of the Tokyo Institute of Technology is leading the Atomic Energy Society panel that's investigating the Fukushima accident.

He told a morning session that experts placed too much confidence in Japan's nuclear power generation and created a nuclear safety myth.

He said the Atomic Energy Society should face the accident head-on and work hard to contain it.

In the afternoon, experts discussed the future of the nuclear energy community. Audience members asked questions.

One participant said the Fukushima disaster occurred because experts did not address the safety risks they knew existed. Another said nuclear officials should cultivate a culture that is more open to public dialogue.

Atomic Energy Society President Satoru Tanaka said experts did not question nuclear safety, even though they had numerous opportunities to do so. The University of Tokyo Professor argued the Society shares responsibility for failing to correct the rigid views of the government and nuclear industry. He promised to continue improving the way experts interact with the public.

Hosono: Cooling down to be achieved this year

Japan's minister in charge of the nuclear disaster says reactors at the troubled Fukushima Daiichi plant will be cooled to below 100 degrees Celsius within this year.

Goshi Hosono spoke at the International Atomic Energy Agency's annual ministerial meeting on Monday.

He thanked the international community for assisting Japan in dealing with the accident at Fukushima.

Hosono said that decontaminated water has been successfully used to cool down the troubled nuclear reactors, bringing the temperature close to 100 degrees Celsius. He also said spent nuclear fuel pools have been cooled in a stable manner.

Hosono also said the spent nuclear fuel has been steadily cooled and will fall below 100 degrees by the end of this year, instead of early next year as initially predicted.

When the reactors and spent fuel have been cooled below 100 degrees, radiation emissions can be kept very low.

The minister also said Japan will work with the IAEA to remove radioactive materials from areas near Fukushima Daiichi.

He explained the plan to separate the Nuclear and Industrial Safety Agency from the Economy, Trade and Industry Ministry, saying it will be merged with the Cabinet Office's Nuclear Safety Commission to create a nuclear safety agency under the Environment Ministry by next April.

Fukushima evacuation warnings to be lifted

The government's evacuation advisories in areas 20 to 30 kilometers from the Fukushima Daiichi nuclear power plant may be lifted by the end of the month.

Residents of 5 municipalities that are mostly in the zone are required to be prepared to evacuate quickly in case of emergency.

Chief Cabinet Secretary Osamu Fujimura announced on Tuesday that the 5 municipalities have all submitted their own recovery plans, and he thinks conditions to lift the advisories have been met.

He said the government will hear views from the Nuclear Safety Commission and then is likely to decide to lift the advisories by the end of September.

Hosono seeks US, French help to scrap reactors

Japan's cabinet minister in charge of the nuclear disaster has asked the United States and France for help in scrapping the reactors at the Fukushima Daiichi power plant.

Goshi Hosono on Monday held separate meetings with US Nuclear Regulatory Commission Chairman Gregory Jaczko, US Energy Secretary Steven Chu and French Industry Minister Eric Besson in Vienna. They are in the Austrian capital for the general assembly of the International Atomic Energy Agency.

Hosono told the officials that the Japanese government is aiming for a cold shutdown of the Fukushima plant before the end of the year.

The government's plan to stabilize the plant originally called for achieving a cold shutdown early next year.

Hosono asked the US and French officials to help with essential work after the cold shutdown, including scrapping the reactors, decontaminating soil and disposing of radioactive waste.

The officials responded positively.

IAEA to send experts to Japan

The International Atomic Energy Agency says it will send experts to Japan to cooperate in the removal of radioactive materials in Fukushima Prefecture.

IAEA chief Yukiya Amano made the remarks on Monday in Vienna. He was responding to a request from Japan's nuclear crisis minister, Goshi Hosono.

Hosono said Japan needs international experience and expertise in order to make progress in the removal of radioactive materials in areas near the Fukushima Daiichi nuclear plant.

He also asked the IAEA for advice regarding stress tests for nuclear reactors in preparation for their restart after checkups. Amano said the agency will help.
After the meeting, Hosono said Japan is removing radioactive materials on a scale that no country has ever experienced.

He went on to say his country will seek advice from the IAEA on how to win public support for the restart of its safety-checked nuclear plants until its new nuclear safety agency is established.
