Nuclear plant operator, Tokyo Electric Power, (TEPCO) released a two and a half minute video taken from the robot that was sent inside the melted reactor on Friday to collect radiation readings and inspect melted fuel.
The robot however, stalled and stopped moving just three hours into a planned 10-hour walk-through. In that time, the snake like robot did manage to collect temperature and radiation readings along with images.
TEPCO announced that spending an hour in the epicenter would kill you. The robot readings showed a deadly 9.7 sieverts per hour from inside the contaminated area of the No. 1 reactor.
The remote-controlled, single use robot revealed 7.0 to 9.7 sieverts per hour readings on site. The temperature level showed cool readings ranging from 17.8 to 20.2 degrees Celsius.
Such radiation levels are way too high for humans to reenter the area even wearing protective suits, according to TEPCO spokesman Teruaki Kobayashi.
The data sent back also revealed that the robot can handle radiation well. The levels were also significantly lower than anticipated, the spokesman announced.
The released video footage showed the robot maneuvering around debris. Kobayashi said that a second robot mission which had been scheduled for Monday had to be postponed as scientist examined the cause of the stalling on Friday. It is feared that treads of the robot were damaged as it moved.
TEPCO plans to send in more robots, including wireless ones, as it tries to acquire data necessary for the site cleanup. The latest footage showed no major obstacles around an opening leading to the underground part of the facility, so more missions are planned to take place.
