13 Years After Tsunami, Nuclear Debris Removed From Fukushima Reactor

A difficult operation to remove a small amount of radioactive debris from Japan's stricken Fukushima nuclear plant began Tuesday, after technical issues suspended an earlier attempt. Tokyo Electric Power Company (TEPCO) said in a statement that its "pilot extraction operation" had started. It will take about two weeks, according to the company.

The tiny sample will be studied for clues about conditions inside the reactors -- a crucial step towards decommissioning the Fukushima Daiichi plant.

Around 880 tons of extremely hazardous material remain 13 years after a tsunami caused by a 9.0-magnitude earthquake triggered one of the world's worst nuclear accidents.

Removing the debris from the reactors is regarded as the most daunting challenge in the decades-long decommissioning project.

TEPCO originally planned to start its first trial removal on August 22, aiming to collect just three grams (0.1 ounces) for analysis -- if the extraction process is successful.

But the company had to stop the work at a preliminary stage after detecting a problem involving the installation of the necessary equipment.

Three of the Fukushima plant's six reactors were operating when the tsunami hit on March 11, 2011, sending them into meltdown.

The debris within has radiation levels so high that TEPCO had to develop specialised robots able to function inside.

TEPCO deployed two mini-drones and a "snake-shaped robot" into one of the three nuclear reactors in February, as part of the preparations for the removal task.

Separately, last year Japan began releasing treated wastewater from the Fukushima plant into the Pacific Ocean, sparking a diplomatic row with China and Russia.

Both countries have banned Japanese seafood imports, although Tokyo insists the discharge is safe, a view backed by the UN atomic agency.

And in a TEPCO initiative to promote food from the Fukushima area, swanky London department store Harrods on Saturday began selling peaches that were grown in the region.

Fukushima peaches are renowned for their juicy, sweet taste -- but they aren't cheap, with one box of three reportedly going for 80 pounds ($100).
