On September 19, Tokyo Electric Power Company (TEPCO) released footage taken inside the reactor containment structure of Unit 3 at the Fukushima Daiichi Nuclear Power Plant, revealing what appeared to be significant damage to the reactor pressure vessel. The footage suggests that the bottom of the pressure vessel may have melted, leading to structural elements inside falling down. Additionally, there were materials resembling icicles or clumps that could potentially be nuclear fuel debris. The investigation was conducted using a micro-drone over the period from September 5 to 19.

TEPCO representatives noted that the findings from the drone footage provide valuable information for further internal investigations and for considering methods for extracting the fuel debris. The observation of melted sections aligns with concerns about the integrity and safety of the reactor containment, as it highlights ongoing issues stemming from the 2011 disaster. TEPCO aims to utilize the data gathered to create 3D visuals of the interior and estimate radiation levels within the containment structure.

The implications of this footage are significant for both the future of the Fukushima site and the broader public perception of nuclear safety in Japan. As TEPCO continues to manage decommissioning efforts, transparency in sharing findings from such investigations will be crucial in addressing public concerns about nuclear energy and its implications for the environment and safety. This development underscores the challenges faced in managing the aftermath of the nuclear disaster, with ongoing efforts needed to clarify the conditions within the reactor structures to ensure the safety of surrounding communities.
