Tepco’s Toughest Robot Fails Inside Fukushima Reactor

‘Tokyo Electric Power Company (Tepco), the owner and operator of the now-defunct Fukushima-1 nuclear plant in Japan, had to pull its toughest radiation-resistant robot out of its Unit 2 reactor prematurely. The robot, built to withstand up to 1000 Sv/hr, failed to last the projected two hours inside the reactor, before starting to glitch.
As Sputnik reported earlier, Fukushima-1 Unit 2 reactor radiation readings had been estimated at “unimaginable” levels of 530 Sv/hr. This level of radiation is beyond extreme, even in comparison to the inside of the Chernobyl reactor, where radiation levels are ‘only’ 34 Sv/hr. The Chernobyl radiation levels are high enough to cause death in humans in about 20 minutes, and Fukushima’s earlier estimation, of 530 Sv/hr, is likely to kill a man in moments. Alarmingly, it is also more than powerful enough to kill purpose-built radiation-protected robots.’
