Two high-tech machines intended to help workers at Japan’s tsunami-hit nuclear plant malfunctioned Friday, including a long-awaited Japanese robot making its first attempt to take important measurements in areas too dangerous for humans.
The other machine that failed was a drone helicopter that made an emergency landing on a reactor roof at the Fukushima Dai-ichi nuclear power plant.
Operator Tokyo Electric Power Co. is trying to cool down three molten reactor cores and stop radiation leaks to end a crisis set off when the March 11 earthquake and tsunami crippled the plant. The job is expected to take several more months, and is complicated by massive amounts of radioactive water that could soon leak into the sea.
