The operator of the tsunami-stricken Fukushima No. 1 nuclear plant will resume an operation to remove a sample of highly radioactive debris this week, The Japan Times reports, after having suspended the effort over a technical snag.
Extracting the estimated 880 tons of highly radioactive fuel and debris inside the former power station remains the most challenging part of decommissioning the facility, which was hit by a catastrophic tsunami in 2011.
Radioactivity levels inside are far too high for humans to enter, and last month engineers began inserting an extendable device to try and remove a small sample.
However, operator Tokyo Electric Power Company Holdings had to halt the procedure after noticing that remote cameras on the apparatus were not beaming back images to the control centre.
Tepco on Friday said it would resume the removal on Monday after replacing the cameras with new ones, the Asahi Shimbun daily and other local media reported.
Tepco officials could not immediately be reached to confirm the reports.
Three of Fukushima’s six reactors went into meltdown after a tsunami triggered by the nation’s biggest earthquake on record swamped the facility in one of the world’s worst nuclear accidents.
Japan last year began releasing into the Pacific Ocean some of the 540 Olympic swimming pools’ worth of reactor cooling water amassed since the catastrophe.
China and Russia banned Japanese seafood imports as a result, although Tokyo insists the discharge is safe, a view backed by the UN atomic agency.
Beijing last month said it would “gradually resume” importing seafood from Japan after imposing the blanket ban.
