Robot retrieves radioactive fuel sample from Fukushima nuclear reactor site
Plant’s owners hope analysis of tiny sample will help to establish how to safely decommission facilityA piece of the radioactive fuel left from the meltdown of Japan’s tsunami-hit Fukushima Daiichi nuclear power plant has been retrieved from the site using a remote-controlled robot.Investigators used the robot’s fishing-rod-like arm to clip and collect a tiny piece of radioactive material from one of the plant’s three damaged reactors – the first time such a feat has been achieved. Should it prove suitable for testing, scientists hope the sample will yield information that will help determine how to decommission the plant. Continue reading...
