TOKYO: A difficult operation to remove a small piece of radioactive debris from Japan’s stricken Fukushima nuclear plant using a robotic device was completed successfully, the plant operator said Thursday, after technical issues halted earlier attempts.
Extracting the estimated 880 tonnes of highly radioactive fuel and debris from Fukushima remains the most challenging part of the decades-long decommissioning process.
But radioactivity levels inside the former power station, which went into meltdown in 2011 after being hit by a catastrophic tsunami, are too high for humans to enter.
So engineers used a specially developed extendible robotic device to remove a sample with a diameter of five millimeters (0.2 inches), aiming to study it for clues about conditions inside the stricken reactors.
The trial debris removal began in September, after an initial attempt in August was suspended at an early stage over a problem with the equipment’s installation.
Another technical snag related to cameras on the apparatus caused a pause of over a month before the procedure resumed in late October.
On Thursday, plant operator TEPCO said it had “completed the trial removal of fuel debris,” declaring the operation a success after several complex steps.
Over the weekend, the robot managed to remove a piece of debris from a containment vessel surrounding a damaged reactor for the first time.
Technicians then tested the radiation level of the sample on Tuesday and put it in a special container.
It will be sent to research institutes in Ibaraki north of Tokyo for analysis, a TEPCO spokeswoman said, adding that the company is still studying when it will be able to start the full-fledged removal of the radioactive debris.
Three of Fukushima’s six reactors were operating when the tsunami hit on March 11, 2011, triggering the worst nuclear disaster since Chernobyl.
Japan last year began releasing into the Pacific Ocean some of the 540 Olympic swimming pools’ worth of treated reactor cooling water amassed since the disaster.
The step sparked a diplomatic row with China and Russia, both of which banned seafood imports, although Japan insists the discharge is safe, a view backed by the UN atomic agency.
Beijing, however, said in September it would “gradually resume” importing seafood from Japan after imposing the blanket ban.

French publisher recalls dictionary over ‘Jewish settler’ reference
- The entry in French reads: “In October 2023, following the death of more than 1,200 Jewish settlers in a series of Hamas attacks”
- The four books are subject to a recall procedure and will be destroyed, Hachette said
PARSI: French publisher Hachette on Friday said it had recalled a dictionary that described the Israeli victims of the October 7, 2023 attacks as “Jewish settlers” and promised to review all its textbooks and educational materials.
The Larousse dictionary for 11- to 15-year-old students contained the same phrase as that discovered by an anti-racism body in three revision books, the company told AFP.
The entry in French reads: “In October 2023, following the death of more than 1,200 Jewish settlers in a series of Hamas attacks, Israel decided to tighten its economic blockade and invade a large part of the Gaza Strip, triggering a major humanitarian crisis in the region.”
The worst attack in Israeli history saw militants from the Palestinian Islamist group kill around 1,200 people in settlements close to the Gaza Strip and at a music festival.
“Jewish settlers” is a term used to describe Israelis living on illegally occupied Palestinian land.
The four books, which were immediately withdrawn from sale, are subject to a recall procedure and will be destroyed, Hachette said, promising a “thorough review of its textbooks, educational materials and dictionaries.”
France’s leading publishing group, which came under the control of the ultra-conservative Vincent Bollore at the end of 2023, has begun an internal inquiry “to determine how such an error was made.”
It promised to put in place “a new, strengthened verification process for all its future publications” in these series.
President Emmanuel Macron on Wednesday said that it was “intolerable” that the revision books for the French school leavers’ exam, the baccalaureat, “falsify the facts” about the “terrorist and antisemitic attacks by Hamas.”
“Revisionism has no place in the Republic,” he wrote on X.
Hamas’s October 7, 2023 attack on Israel resulted in the deaths of 1,221 people, with 251 people taken hostage, according to an AFP tally based on official Israeli figures.
Authorities in Gaza estimate that more than 70,000 people have been killed by Israeli forces during their bombardment of the territory since, while nearly 80 percent of buildings have been destroyed or damaged, according to UN data.
Israeli forces have killed at least 447 Palestinians in Gaza since a ceasefire took effect in October, according to the Hamas-run health ministry.
