Japan’s Fukushima nuclear plant further delays removal of melted fuel debris

Daily Mail, 26 Jan 24, TOKYO (AP) – The operator of the tsunami-hit nuclear plant in Fukushima announced Thursday a delay of several more months before launching a test to remove melted fuel debris from inside one of the reactors, citing problems clearing the way for a robotic arm.

The debris cleanup initially was supposed to be started by 2021, but it has been plagued with delays, underscoring the difficulty of recovering from the plant’s meltdown after a magnitude 9.0 quake and tsunami in March 2011……………………………………………

About 880 tons of highly radioactive melted nuclear fuel remain inside the three damaged reactors. Critics say the 30- to 40-year cleanup target set by the government and TEPCO for Fukushima Daiichi is overly optimistic. The damage in each reactor is different and plans need to be formed to accommodate their conditions.

TEPCO has previously tried sending robots inside each of the three reactors but got hindered by debris, high radiation and inability to navigate them through the rubble, though they were able to gather some data in recent years.

Getting more details about the melted fuel debris from inside the reactors is crucial for their decommissioning. TEPCO plans to deploy four mini drones and a snake-shaped remote-controlled robot into the No. 1 reactor’s primary containment vessel in February to capture images from the areas where robots have not reached previously……………….  https://www.dailymail.co.uk/wires/ap/article-13006423/Japans-Fukushima-nuclear-plant-delays-removal-melted-fuel-debris.html
