Extremely high radiation breaks down Fukushima clean-up robot at damaged nuclear reactor

A clean-up mission using a remotely operated robot at Japan’s crippled Fukushima nuclear plant has had to be aborted, as officials feared they could completely lose control of the probe affected by unexpectedly high levels of radiation.

The robot equipped with a high-pressure water pump and a camera designed to withstand up to 1,000 Sieverts of cumulative exposure had been pulled off the inactive Reactor 2 at the Fukushima Daiichi nuclear complex earlier this week, The Japan Times reported Friday, citing the plant operator, Tokyo Electric Power Company (TEPCO). The device reportedly broke down just two hour into the probe.

The failure led experts to rethink estimated levels of radiation inside the damaged reactor.
