"Unanswered Questions: New Images Inside Melted Fukushima Reactor"

Images taken by miniature drones from inside the damaged Fukushima reactor show displaced control equipment and misshapen materials, leaving many questions unanswered about the location and condition of the highly radioactive melted nuclear fuel. The drones' high-definition color images revealed brown objects of various shapes and sizes dangling from the pedestal, but officials were unable to determine whether they were melted fuel or equipment without additional data. The daunting task of decommissioning the plant, which has been delayed for years by technical hurdles and lack of data, remains a significant challenge.

"Unanswered Questions: Inside the Melted Fukushima Reactor"

Images taken by miniature drones inside the damaged Fukushima reactor show displaced control equipment and misshapen materials, leaving many questions unanswered about the location and condition of the highly radioactive melted nuclear fuel. The 12 photos released by the plant’s operator, TEPCO, reveal brown objects of various shapes and sizes dangling from the pedestal, but it remains unclear whether they are melted fuel or equipment. The lack of information highlights the difficulty of the decommissioning process, which has already been delayed for years by technical hurdles and the lack of data.

"Unveiling the Damage: Deep Inside the Melted Fukushima Reactor"

Miniature drones captured the first images from inside the main structural support of the Fukushima No. 1 reactor, revealing displaced control equipment and misshapen materials. The photos, released by the plant's operator, highlight the challenges of decommissioning the plant and the difficulty in assessing the condition of the melted nuclear fuel. The 880 tons of highly radioactive melted nuclear fuel inside the damaged reactors present a daunting task for Tokyo Electric Power Company Holdings (TEPCO), which is attempting to gather more information to facilitate its removal. However, the lack of data and the unknown interior of the reactors suggest that the cleanup process may be overly optimistic and face significant delays.

Dam collapse leaves Ukrainian nuclear plant workers without water.

Workers at the Zaporizhzhia Nuclear Power Plant in Ukraine are struggling to secure water after a nearby dam collapsed, depleting its water supply. The plant has shut down all six reactors, but will still require water to cool spent fuel and other equipment. The International Atomic Energy Agency believes the water in the plant's cooling pond and other parts should be enough to cool the plant for the next few months. The collapse of the dam was preceded by an explosion, and evidence suggests that it was blown up by a Russian "sabotage group."
