Robot spots suspected debris of melted fuel for first time since 2011 earthquake and tsunami destroyed the plant

theguardian.com - Associated Press - July 22, 2017

Images captured by an underwater robot on Saturday showed massive deposits believed to be melted nuclear fuel covering the floor of a damaged reactor at Japan’s destroyed Fukushima nuclear plant.

The robot found large amounts of solidified lava-like rocks and lumps in layers as thick as 1m on the bottom inside a main structure called the pedestal that sits underneath the core inside the primary containment vessel of Fukushima’s Unit 3 reactor, said the plant’s operator, Tokyo Electric Power Co.

On Friday, the robot spotted suspected debris of melted fuel for the first time since the 2011 earthquake and tsunami caused multiple meltdowns and destroyed the plant.

TEPCO Chair: Nuclear Plant Must Release Contaminated Water

           

Tokyo Electric Power Co.'s new Chairman Takashi Kawamura speaks during an interview at the TEPCO headquarters in Tokyo on Thursday, July 13, 2017. Kawamura said the utility needs to stop dragging its feet on plans to dump massive amounts of treated but contaminated water into the sea and make more money if it’s ever going to succeed in cleaning up the mess left by meltdowns more than six years ago at the tsunami-hit Fukushima nuclear power plant.

. . . Takashi Kawamura, an engineer-turned-business leader who previously headed Hitachi's transformation into a global conglomerate, is in charge of reviving TEPCO and leading the cleanup at the Fukushima Dai-Ichi plant. In an interview Thursday with selected media including The Associated Press, Kawamura said despite the massive costs of the cleanup and meeting tighter safety requirements, nuclear power is still vital for Japan's national security.

Below are highlights from the interview, where Kawamura spoke in Japanese:

Dying Robots and Failing Hope: Fukushima Clean-Up Falters Six Years After Tsunami

Exploration work inside the nuclear plant’s failed reactors has barely begun, with the scale of the task described as ‘almost beyond comprehension’

theguardian.com - by Justin McCurry - March 8, 2017

 . . . As the 60cm-long Toshiba robot, equipped with a pair of cameras and sensors to gauge radiation levels was left to its fate last month, the plant’s operator, Tokyo Electric Power (Tepco), attempted to play down the failure of yet another reconnaissance mission to determine the exact location and condition of the melted fuel . . .

 . . . The Scorpion mishap, two hours into an exploration that was supposed to last 10 hours, underlined the scale and difficulty of decommissioning Fukushima Daiichi – an unprecedented undertaking one expert has described as “almost beyond comprehension”.

Cleaning up the plant, scene of the world’s worst nuclear disaster since Chernobyl after it was struck by a magnitude-9 earthquake and tsunami on the afternoon of 11 March 2011, is expected to take 30 to 40 years, at a cost Japan’s trade and industry ministry recently estimated at 21.5tr yen ($189bn).

Highest Radiation Reading Since 3/11 Detected at Fukushima No. 1 Reactor

           

Based on image analysis, a two-meter hole has been found in the metal grate under a pressure vessel in reactor No. 2's containment vessels at the Fukushima No. 1 nuclear power plant. | TOKYO ELECTRIC POWER COMPANY HOLDINGS INC. / VIA KYODO

japantimes.co.jp - KYODO, STAFF REPORT

The radiation level in the containment vessel of reactor 2 at the crippled Fukushima No. 1 power plant has reached a maximum of 530 sieverts per hour, the highest since the triple core meltdown in March 2011, Tokyo Electric Power Co. Holdings Inc. said.

Tepco said on Thursday that the blazing radiation reading was taken near the entrance to the space just below the pressure vessel, which contains the reactor core.

The high figure indicates that some of the melted fuel that escaped the pressure vessel is nearby.

At 530 sieverts, a person could die from even brief exposure, highlighting the difficulties ahead as the government and Tepco grope their way toward dismantling all three reactors crippled by the March 2011 disaster.

About 71 years after the United States dropped a nuclear bomb on Hiroshima, Japan, President Obama visited the site and placed a wreath before the cenotaph at the Hiroshima Peace Memorial Park. It is the first visit by a “sitting U.S. President.” Both Japanese Prime Minister Shinzo Abe and President Obama delivered speeches, and Obama spoke out against nuclear weapons.

Japan: Fukushima Clean-Up May Take Up To 40 years, Plant's Operator Says

Cleaning up Japan's Fukushima Daiichi nuclear plant, which suffered catastrophic meltdowns after an earthquake and tsunami hit in 2011, may take up to 40 years.

The crippled nuclear reactor is now stable but the decommissioning process is making slow progress, says the plant's operator Tokyo Electric Power Co, better known as TEPCO. . . .

. . . The biggest obstacle to closing down the plant permanently is removing all the melted nuclear fuel debris from three reactors, Ono told reporters after a press tour of the plant this week.

But TEPCO says it is in the dark about the current state of the debris.

Japanese Ebola test gives results in 11 minutes: researcher

AFP     April  9, 2015

Tokyo  A Japanese research team said on Thursday it had developed a field test for Ebola that gives results in just over 11 minutes -- down from the 90-minute test used now.

The breakthrough by Nagasaki University's Institute of Tropical Medicine will allow medics to move much more quickly in treating people with the haemorrhagic fever, Professor Jiro Yasuda told AFP.

"The result time was unexpectedly short," said Yasuda of the trial conducted in Guinea last month on 100 samples, of which 47 proved positive.

The Guinean government has now asked the institute and its collaboration partner Toshiba to supply equipment to roll out the test, he added.

New tests show almost all of the fuel inside one of the Fukushima plant's reactors has melted, its operator said Thursday, the latest step in the clean up after Japan's worst ever nuclear crisis.

Tokyo Electric Power Co. said the technology, which uses elementary particles called "muon" to create x-ray style images, gave the most concrete evidence yet the fuel had dropped to the bottom of the first reactor.

After four months, North Korea’s Ebola quarantine comes to an end

WASHINGTON POST  BY 

TOKYO — North Korea has lifted its four-month-long Ebola quarantine, bringing an end to a period of isolation that was notable even by the Hermit Kingdom’s standards.

Embassies and international aid agencies in Pyongyang received a "note verbale" from North Korea's State Emergency Anti-Epidemic Committee informing them that the quarantine was now over for all visitors except for those arriving from a handful of west African countries. Tour operators have also been informed by their North Korean partners and the state airline that the borders are being re-opened.

With no cases of the virus east of Africa, the strictly-enforced 21 day quarantine for everyone entering North Korea — locals and foreigners alike — was puzzling and inevitably sparked theories about what the ban could really be about.

Ebola: World Bank and Liberia to Work with Japan to Launch a Psychological Support Project

Some 18,000 Beneficiaries to Receive Mental Health and Psychosocial Support to Alleviate Consequences of Epidemic

worldbank.org

MONROVIA, February 25, 2015 – The Liberian Government and the World Bank Group in partnership with the Government of Japan, today launched a new $3 million project to address the psychological effects of Liberia’s Ebola crisis and to promote psychosocial health in the country. The ceremony was held at the World Bank Liberia Office.

The project, Supporting Psychosocial Health and Resilience in Liberia, is funded by Japan through the Japanese Social Development Fund (JSDF), a trust fund administered by the World Bank. The Carter Center will implement this three-year project, which is expected to reach approximately 18,000 beneficiaries in Montserrado (hosting Monrovia) and Margibi counties.
