podcast I listened to a podcast about "Robot Explores Fukushima Reactor". This robot entered a damaged reactor at Japan's Fukushima nuclear plant this week to take pictures of the reactor destroyed by an earthquake and tsunami in 2011. The robot, nicknamed 'The Little Sunfish,' is very small. It has lights, five propellers, and two cameras, among other data collection tools. In previous tests, two robots became stuck inside two of the plant's other reactors. Scientists need to know the melted fuel’s exact location and understand the damage in each of the three wrecked reactors. Kimoto said the Little Sunfish showed that the Unit 3 reactor chamber was “clearly more severely damaged” than Unit 2, which was explored by the scorpion probe. This information will help them to decide on the safest and most efficient ways to remove the fuel. Japanese officials say they want to decide on methods for removing the melted nuclear fuel this summer. They hope to start the removal work in 2021.
