Fukushima: ‘Warrior’ Robot Vacuums Reactor 3 Floor, Radiation Still Very High

#Fukushima I Nuke Plant: “Warrior” Robot Vacuumed Reactor 3 Floor, Radiation Still Very High (Ex-SKF, July 2, 2011):

Yomiuri Shinbun reports that the “Warrior” robot from iRobot went inside the reactor building for the Reactor 3 to vacuum the highly radioactive (or so TEPCO thought) sands accumulated on the floor right off the truck entrance.

It completed the task, braving the high radiation (more than 100 millisieverts/hour in some spots) on July 1. It took the robot 5 hours to collect dust and sand in 3 200-liter containers.

Unfortunately, the radiation level in the area only went down by 10 to 20 millisieverts/hour, and TEPCO is considering laying down the steel plates on the floor to see if they block the radiation.

See “Warrior” in action, as videoed by the fellow iRobot “Packbot”, which was then screen-captured by TEPCO on a notebook PC screen:
