Radioactive cesium levels 90% higher in Fukushima groundwater

Fukushima Groundwater Shows Record Radiation Levels HUFFINGTON POST, Reuters 07/09/2013 “……SITUATION WORSENS Tokyo Electric Power Co, the operator of the Fukushima station, hit by the March 2011 earthquake and tsunami, said that an observation well between the damaged reactor No. 2 and the sea showed levels of radioactive caesium-134 were 90 times higher on Monday than they had been the previous Friday.

Tokyo Electric, also known as Tepco, said it detected caesium-134 at 9,000 becquerels per litre, 150 times above Japan’s safety standard. A becquerel is a measure of the release of radioactive energy. The reading for caesium-137, with a half life of 30 years, was some 85 times higher than it had been three days earlier.

The latest findings, 25 metres from the sea, come a month after Tepco detected radioactive caesium in groundwater flowing into its wrecked plant far from the sea on elevated ground. The level of caesium found in June was much lower than the amount announced on Tuesday.

The spike, combined with recent discoveries of high levels of radioactive elements like tritium and strontium, suggest that contaminated water is spreading toward the sea side of the plant from the reactors sitting on higher ground…..

The operator has been flushing water over the three reactors to keep them cool for more than two years, but contaminated water has been building up at the rate of an an Olympic-size swimming pool per week. In April, Tepco warned it may run out of space to store the water and asked for approval to channel what it has described groundwater with low levels of radiation around the plant and to the sea through a “bypass”. Local fishermen oppose the proposal….. http://www.huffingtonpost.com/2013/07/09/fukushima-groundwater-radiation_n_3565767.html

Fukushima groundwater has radioactive contamination

Toxic radiation detected in groundwater at Fukushima nuclear plant Raw Story France-Presse July 7, 2013 Toxic radioactive substances have once again been detected in groundwater at the crippled Fukushima nuclear plant, its Japanese operator said on Sunday, the latest in a series of incidents at the tsunami-battered complex.

Tokyo Electric Power Co (TEPCO) said tests showed that tritium, a radioactive isotope of hydrogen used in glow-in-the-dark watches, was present at levels 10 times the permitted rate. “From test samples on July 5… we detected a record high 600,000 becquerels per litre” of tritium, 10 times higher than the government guideline of 60,000 becquerels per litre, TEPCO said in a statement….

The new readings came after TEPCO said in late June that it had detected the highly toxic strontium-90, a by-product of nuclear fission that can cause bone cancer if ingested, at levels 30 times the permitted rate. At the time it had detected tritium at around eight times the allowed level, or 500,000 becquerels per litre.

The substances, which were released by the meltdowns of reactors at the plant in the aftermath of the huge tsunami of March 2011, were not absorbed by soil and have made their way into underground water.

Subsoil water usually flows out to sea, meaning these two substances could normally make their way into the ocean, possibly affecting marine life and ultimately impacting humans who eat sea creatures…. http://www.rawstory.com/rs/2013/07/07/toxic-radiation-detected-in-groundwater-at-fukushima-nuclear-plant/

Tepco rushes effort to restart two nuclear reactors, ignores local councils

TEPCO gets harsh response from Niigata gov. over restarting reactors Global Post 5 July 13 Tokyo Electric Power Co. faced a harsh response on Friday from Niigata Gov. Hirohiko Izumida in its attempt to swiftly apply for a state safety assessment of two reactors there as a step toward resuming their operations.

After meeting with Izumida and the mayors of two municipalities that the Kashiwazaki-Kariwa plant straddles, TEPCO President Naomi Hirose admitted it is “difficult” to join other utilities’ moves to apply for safety assessment of reactors next Monday, when a set of new regulations for atomic power plants take effect.

Izumida said TEPCO did not offer any explanation to local people before announcing the company’s plan to file for the assessment of the plant’s Nos. 6 and 7 reactors.

“Why did you rush (to make a decision to file for application)?” the governor said in the meeting, while also refusing to accept a paper in which TEPCO sought approval on a plan to install a safety system which is essential to restart the two units under the new safety standards…… http://www.globalpost.com/dispatch/news/kyodo-news-international/130705/tepco-gets-harsh-response-niigata-gov-over-restarting-

Fukushima Prefecture voters stress the reality of the nuclear crisis

Fukushima voters urge politicians to face reality of nuclear crisis Global Post 5 July 13 Voters in Fukushima Prefecture, where about 150,000 people are still living as evacuees from their homes due to the nuclear disaster triggered by the 2011 earthquake and tsunami, urged politicians to face the reality of the crisis as official campaigning for the July 21 House of Councillors election got under way Thursday…….

Yasuo Yoshida, a 46-year-old fisherman in Iwaki, a coastal city in the prefecture, said politicians should visit the areas affected by the nuclear disaster more often and listen to the local people.

“Now we face a moment of truth in trying to rebuild Fukushima’s fishing industry and I want politicians to ensure that the central government will take responsibility” for the revival of fishing, he said. Continue reading →

Highest radiation levels for 12 months found at Fukushima

Fukushima records highest radiation level in a year http://www.straight.com/blogra/398066/fukushima-records-highest-radiation-level-year by CHARLIE SMITH on JUL 4, 2013 You might think that radiation levels would be falling more than two years after Japan’s most serious nuclear disaster since the bombing of Nagasaki in the Second World War.

But on a rooftop in Fukushima, radioactive cesium levels were at the highest levels observed in the past year, according to the Asahi Shumbun newspaper. The publication reported that University of Tokyo associate professor Ryoji Enomoto found moss with 1.7 million becquerels just over 50 kilometres from a crippled nuclear-power plant.

This was confirmed by a nonprofit group, the newspaper noted. According to an article by David Chandler of the Massachusetts Institute of Technology, a dose of 500 millisieverts can cause symptoms of radiation poisoning. It’s not easy converting becquerels, which measures radiation emitted, to millisieverts, which measure biological damage.

But you would likely want to move if levels of 1.7 million becquerels were ever detected in your neighbourhood.

Japan’s nuclear industry has poor safety culture

Japan: Building Nuclear Safety Culture Will Take ‘Long Time’ VOA, Reuters July 04, 2013 TOKYO — Japan’s nuclear regulator said on Thursday that elevating safety culture to international standards will “take a long time.” That assessment came days before new rules take effect that aim to avoid a repeat of the Fukushima nuclear disaster that occurred in March 2011………..

“The new regulations include extremely stringent requirements that the operators would not be able to endure if they don’t change their culture,” authority chairman Shunichi Tanaka told reporters. “We will need a long time to change this culture, but day-to-day efforts to meet those tough standards will in the end lead to the improvement in the safety culture.”
Trying to restart
Tokyo Electric Power Co., operator of the Fukushima plant that had three meltdowns, Kansai Electric Power Co., and three other listed nuclear operators have said they will apply for restarts after the rules go into effect.

Tanaka declined to comment on whether he considered Tokyo Electric – still struggling to contain leaks and power cuts at its ravaged plant – fit to operate nuclear facilities. He added that whether the company will be given a green light would depend on the contents of its application…….

Upgrades required by the Nuclear Regulation Authority in its quest to impose the world’s toughest earthquake and tsunami standards will cost the industry an estimated $12 billion, according to Tom O’Sullivan, an independent energy analyst based in Tokyo.

Tanaka stressed that the new regulator had what it took to impose the new regulations. “We have large authority and powers. If the operator does not comply with our regulations, they won’t be able to operate, let alone restart their reactors,” he said.http://www.voanews.com/content/japan-says-building-nuclear-safety-culture-will-take-long-time/1695038.html

Shutdown in September for Japan’s only two operating nuclear power units

Japan’s only two operating nuclear units to shut in September: regulator Tokyo (Platts)–4 Jul 2013 Kansai Electric Power Co can continue operating Ohi-3 and -4, the only nuclear units running in Japan, until they will have to be shut for maintenance in September, Nuclear Regulation Authority commissioners agreed unanimously Wednesday.

Ohi-3 and -4 can run until September 2 and 15, respectively. Japanese law allows reactors 13 months of continuous operation before they must shut for maintenance.
The units, each with gross capacity of 1,180 MW, are sometimes referred to as Ooi and are the largest of Kansai EPC’s 11 power reactors.

Ohi-3 and -4 were assessed against NRA’s safety requirements, which will come into force Monday. The assessment of the units, including an inspection of the site June 15, found they “will not cause serious safety problems immediately,” a 46-page NRA staff document said.

Japan’s other 48 operational nuclear units have remained down after completing maintenance and refueling outages following the March 11, 2011 earthquake and tsunami that resulted in permanent shutdowns of units 1 through 4 at Tokyo Electric Power Co.’s Fukushima I……….http://www.platts.com/latest-news/electric-power/Tokyo/Japans-only-two-operating-nuclear-units-to-shut-26076364

Date: June 25, 2013

A Japanese prime ministerial envoy secretly promised to the United States that Japan would resume its controversial “pluthermal” program, using light-water reactors to burn plutonium, according to documents obtained by the Mainichi.

The secret promise was made by Hiroshi Ogushi, then parliamentary secretary of the Cabinet Office, to Daniel Poneman, deputy secretary of the U.S. Department of Energy, during Ogushi’s visit to the United States on behalf of then Prime Minister Yoshihiko Noda in September last year.

[…] The fact that a Japanese official promised to the U.S. to implement such a controversial project without a prior explanation to the Japanese public is expected to stir up controversy. […]

“It is abnormal for sure,” said one official with the Agency for Natural Resources and Energy. […]

Water in all leaky trenches at No. 1 routed to other storage, Tepco says

Tokyo Electric Power Co. has finished pumping out radioactive water from all seven of its huge covered trenches at the crippled Fukushima No. 1 nuclear plant […]

[…] It was found that the highly radioactive water that had been pumped into the trenches, which are triple-lined, was seeping into the ground. […]

The less-contaminated water was pumped into the basement of the reactor 6 turbine building and will eventually be transferred to above-ground containers, Tepco said late Monday. […]

Japan’s wind energy systems to increase, with off shore turbines

What is not well known is that Japan has considerable wind power, and that its string of wind turbines continued to function throughout the 2011 tsunami disaster.

Work starts on Fukushima floating project Wind Power Monthly 25 June 2013 by Martin Foster, JAPAN: Installation of wind turbines in the testing phase of the biggest offshore floating project to date will finally get under way this week, 20 kilometres off the coast of Fukushima. Two 2MW downwind floating turbines are scheduled to be towed from shipyards belonging to Mitsui Engineering and Shipbuilding in Chiba prefecture to Onahama port on 28 June, according to a new schedule released by Takeshi Ishihara a civil engineering professor at the University of Tokyo and technical adviser to the project…….

The cable is scheduled to be loaded on ship, laid and sunk in the seabed from the end of July until the end of August. It is planned to connect the cable some time in the month of August, with the project due to start generating power in mid-September.

The massive floating wind farm project, which is being developed by an 11-entity consortium lead by Marubeni Corporation, may eventually see 132 floating turbines come on line. It has been named Fukushima Mirai, literally the future of Fukushima, and has been planned as part of post-nuclear disaster recovery efforts in the area.

The project fulfils a ten-year dream for Ishihara.

“I feel that we have taken the first real step towards finally realising the dream I have embraced for the past ten years. I am really pleased,” he told Windpower Monthly. http://www.windpowermonthly.com/article/1187536/work-starts-fukushima-floating-project

Japan’s nuclear industry hope to restart, but delay safety upgrades

I couldn’t help being reminded of Saint Augustine’s famous prayer – “God make me pure – but not yet!”

The cost of upgrading all of the nuclear power plants is expected to exceed ¥1 trillion.

Nuclear safety rules put onus on utilities Japan Times, BY KAZUAKI NAGATA , 1 July 13, The Nuclear Regulation Authority on July 8 will begin enforcing new safety standards at atomic power stations, more than two years after Tokyo Electric Power Co.’s Fukushima No. 1 plant experienced three reactor core meltdowns…………

Utilities are meanwhile hoping that the regulators will be lenient with reactor restarts as long as they agree
to upgrade their plants to the new safety regime over time……

A major difference is that it will now be mandatory for utilities to install defenses that can prevent meltdowns from being caused by natural disasters — such as earthquakes, tsunami and tornadoes — as well as defenses against terrorist attacks…… Continue reading →

A bad idea, burning radioactive trash in Fukushima

Nuclear Information and Resource Service Now here’s a bad idea: Tepco building incinerator for Fukushima radwaste. Will spread radiation through the air. http://bit.ly/11YFs9M Fukushima waste incinerator takes shape Construction of an incinerator is underway at the Fukushima Daiichi plant to burn the low-level waste (LLW) being generated from the clean-up and decommissioning of the site. (Diagram of planned incinerator below)

Update:

Small fire reported at Fukushima nuclear plant

National Jul. 02, 2013 – 04:00PM JST ( 11 )

TOKYO —

A fire broke out in a rubbish pile at the crippled Fukushima Daiichi nuclear complex on Tuesday, the operator said, the latest in a series of incidents at the crippled plant.

Workers discovered flames licking at piles of cardboard boxes placed near an incineration facility shortly before 1 p.m., Tokyo Electric Power Co said.

The fire damaged an area of about four meters by two meters, but was put out in a hour, it said.

The fire did not affect radiation levels in the plant, and no one was injured, it said.

TEPCO has struggled with a growing number of incidents at the plant including several leaks of radioactive water, more than two years after the worst nuclear disaster in a generation.

Improvised fixes put in place since the disaster leave it vulnerable to problems and at the mercy of nature, with no immediate end in sight, critics say.

Tepco’s nuclear decommissioning plan rubbished by regulators

There is apparently no “Plan B” if the fuel debris cannot be removed. The Agency for Natural Resources and Energy said in the meeting that the reason why the concrete steps toward removing the fuel debris ahead of schedule was not mentioned in the roadmap was because they couldn’t figure out those steps yet.

NRA has been consulted, never mind that the commissioners and experts blasted their plan. For TEPCO and the government, particularly the government, a mere gesture of consulting with NRA is more than enough for procedural purposes.

Looking at TEPCO’s plan for fuel debris removal, as posted at NRA’s site, it is painfully clear that TEPCO was told by the Agency what to write (garbage).
