Fukushima Workers Flee Site After Tsunami Scare
Japan is one of the most earthquake-prone areas in the world, and the regular quakes raise traumatic memories of the March 11, 2011, record-breaker that left 19,000 dead and smashed the six-reactor Fukushima-Daiichi site. A magnitude 5.5 quake struck just off Japan’s southeast Tokara coast on July 3; a mag. 4.2 quake hit east of Iwaki, in Fukushima Prefecture July 12; and a mag. 4.1 quake shook the same area July 25.
In late July, a mighty 8.8-magnitude quake struck Avacha Bay in Russia’s Far East, triggering tsunami warnings and evacuations across the entire Pacific Rim. The U.S. Geological Survey said the earthquake was one of the strongest ever recorded.
The owner/operator of the wrecked reactor complex, Tokyo Electric Power Co., evacuated its entire staff of 4,000 in response to warnings of a possible nine-foot tsunami, after first halting its pumping of radioactive wastewater into the Pacific.
Elsewhere in Japan, over 1.9 million people were urged to evacuate the eastern seaboard, and a 4-foot tsunami wave did strike north of Fukushima at Iwate Prefecture, some 1,090 miles from Avacha Bay, site of the major Russian earthquake.
China partially lifts ban on Japanese seafood imports
China “conditionally resumed” the importation of Japanese seafood products June 30 ⸺ except the 10 prefectures closest to the Fukushima disaster site ⸺ after conducting water sample inspections off the coast of the site. Beijing had banned all such imports from Japan as a protest and precaution, following the 2023 start of deliberately discharging large volumes of radioactively contaminated cooling water into the Pacific Ocean. The 2023 ban was imposed to “comprehensively prevent the food safety risks of radioactive contamination caused by the discharge of nuclear wastewater from Fukushima into the sea,” China’s General Administration of Customs said then. Shocked by Japan’s action, Beijing’s Foreign Ministry added that the discharge was an “extremely selfish and irresponsible act,” which would “push the risks onto the whole world (and) pass on the pain to future generations of human beings,” the Agence France-Presse reported.
Chinese customs officials said June 30 the seafood import ban would continue for ten prefectures, namely Fukushima and its nine closest neighboring states. Products from other regions will need health certificates, radioactive substance detection qualification certificates, and production area certificates issued by the Japanese government for Chinese customs declarations, the government said.
Relatedly, Hong Kong announced that it will maintain its ban on Japanese seafood, sea salt, and seaweed imports from the same ten prefectures still targeted by mainland China ⎯ Fukushima, Gunma, Tochigi, Ibaraki, Miyagi, Niigata, Nagano, Saitama, Tokyo, and Chiba ⎯ citing ongoing concerns about the risks associated with the discharge of radioactive wastewater.
Tepco Lost $6 Billion as Meltdown Recovery Falters
Tokyo Electric Power Co. Holdings corporation (Tepco) lost $5.8 billion (903 billion yen) between April and June this year as the owner and operator of the triple reactor meltdown at Fukushima, overrun with the costs of inventing, designing, building, and testing robotic machines with which to remotely extract the ferociously radioactive melted reactor fuel from deep inside the earth-quake and tsunami-wrecked reactors. There are a total of over 880 metric tonnes of “corium” or melted and rubblized uranium and plutonium fuel in three reactors that Tepco claims it will extract. Nikkei-Asia reported August 1st that Tepco says it has $4.7 billion “earmarked for future demolition work” (700 billion yen), which doesn’t even cover this spring’s one-quarter loss. Tepco has said that its preparations for the extraction are “expected to take 12 to 15 years.”
The quarterly financial loss makes a mockery of announced plans by the government and TEPCO to fully complete decommissioning of the rubbished reactors by 2051.
Two out of 14-to-20-million tonnes of radioactive soil buried on PM’s office grounds, in “safety” parody
In a surreal display of political slapstick on July 19th, the office of Japan’s Prime Minister Shigeru Ishiba buried on his office’s garden grounds two cubic meters of radioactive soil scraped up during Fukushima clean-up operations (in which some 14-to-20 million cubic meters of topsoil and debris were collected) ⎯ “to show it is safe to reuse.”
Nippon Television reported that “The radioactive cesium concentration in the soil being buried is 6,400 Becquerels per kilogram” (Bq/kg). “Becquerels” are a standard measuring unit of radioactivity. The 6,400 is below the legally permitted limit of 8,000 Bq/Kg.
The radiation emitted by the soil originates from cesium-137, which was released in large amounts by Fukushima’s melting and exploding reactors and subsequently fell to the ground as fallout. Cesium fallout continues to contaminate vast areas of forest and farmland in the region.
The millions of tons of collected soil now in storage are being tested and sorted to identify material with cesium at 8,000 Bq/Kg or less. Several million tons of it may then be used as fill in construction projects, road-building, and railway embankments all around Japan. Asphalt, farm soil, “or layers of other materials should be used to seal in the radioactivity,” Akira Asakawa, an Environment Ministry official with the soil project, told the Agence France-Presse.
The PM’s demonstration plot is the first “reuse” of the poisoned waste, while experiments elsewhere have been halted due to public protest. The PM’s contaminated dirt was covered up with about eight inches of normal soil to provide some radiation shielding.
Any radiation exposure is unsafe, but adverse effects like radiation sickness, immune disorders, or cancers caused by contact with the radioactive soil would take years or decades to appear, owing to the latency period between radiation exposure and the onset of induced health problems. The joke seems to be that since Prime Minister Ishiba hasn’t dropped dead after walking by, low-dose exposure must be harmless.
Readers may remember a very similar high-level comedy sketch performed by former President Barack Obama, who traveled to Flint, Michigan in May 2016. Drinking water supplies there had been contaminated with lead and to calm the public uproar, Obama sat before the cameras and theatrically downed a glass of water. The straight-faced routine was proof positive and rock-solid confirmation beyond a doubt that Flint’s tap water was safe to drink. Bottom’s up!
Fukushima Disaster Response to Last Eons
Countless dilemmas and setbacks have plagued the now 14-year-long emergency response to the triple reactor meltdown and widespread radiation releases that began on March 11, 2011, at Fukushima on Japan’s northeast coast.
Perhaps the most significant stumbling block, acknowledged by Tepco on July 29, is the “unprecedented” technical complexity of locating, contacting, removing, and containerizing 880 tonnes of highly radioactive melted reactor fuel still smoldering at the bottom of the three devastated reactors.
Unprecedented is the key word here, since the industry has never before had to contain such a large mass of wasted and unapproachable radioactivity. All the work of dealing with the wasted fuel must be done robotically and remotely, since the waste’s fierce radioactivity kills living things that come near. Just planning and preparing to remove the “corium” material will take at least another 12 years.
Toyoshi Fuketa, head of a regulatory body overseeing the site, said at a press conference earlier that “The difficulty of retrieving the first handful of debris has become apparent,” the Kyodo News agency reported.
In 14 years’ time, engineers managed to design, build, test, and rebuild a one-of-a-kind robot that removed less than one-gram of the waste fuel from reactor No. 2 last year. That November “breakthrough” was three years behind schedule, “and some experts estimate that the decommissioning work could take more than a century,” CBS News and Mainichi Japan reported.
The torturously slow process has made Tepco’s early prediction of complete cleanup by 2051 (40 years’ time) appear to have been made up for PR reasons.
Tepco said July 29 that it would need another 12 to 15 years’ worth of preparation ⎯ until 2040 ⎯ “before starting the full-scale removal of melted fuel” at the No. 3 reactor. Tepco earlier claimed that “full-scale” extraction would begin four years ago, in 2021 according to the daily Asahi Shimbun August 1.
Of an estimated 880 tons of debris, only 0.9 grams have been recovered to date. With one million grams in a tonne, Tepco has only 879 million-plus grams to go, and “A simple calculation based on the time since the accident suggests the removal process could take another 13.6 billion years to complete,” the Asahi Shimbun smirked.
China’s reactor report card omits embarrassing emission info’
China issues annual reports on its extensive nuclear power operations known as “China Nuclear Energy.” The 2024 edition, its latest, made headlines by omitting for the first time information on the routine radioactive gases and liquids released from its operating reactors.
Kyodo News reported that the omission may be a way to avoid accusations of hypocrisy, as China has strenuously condemned Japan’s discharge of radioactively contaminated wastewater into the Pacific. At the same time China’s domestic reactors in 2022 reportedly “released wastewater containing tritium at levels up to nine times higher than the annual discharge limit” set by Japan’s discharge authorities. ###
