How does Tepco's debris retrieval fit into the long-term decommissioning of Fukushima?
The retrieval of radioactive debris is a crucial step in Tepco's long-term decommissioning plan for the Fukushima Daiichi Nuclear Power Plant. This process involves the careful removal of an estimated 880 tons of melted nuclear fuel and debris, which is expected to take over a century to complete. The current mission to collect debris from the No. 2 reactor is part of ongoing efforts to develop technology and methods for larger-scale cleanup operations.

What was the impact of the 2011 earthquake and tsunami on the Fukushima plant?
The Fukushima Daiichi Nuclear Power Plant suffered catastrophic meltdowns in March 2011 due to a powerful earthquake and tsunami. This disaster led to the release of radioactive materials and the need for extensive decommissioning efforts. The ongoing retrieval of debris is part of Tepco's response to the long-term consequences of this environmental crisis.
