Survey runner robot stopped on the radiation measurement of torus room in reactor3.

From 11:00 to 15:00 of 7/11/2012, Tepco was taking radiation, visual and “sound” data in torus room of reactor3 by using a robot. The atmospheric dose was 360 mSv/h.

Human worker opened the door of the torus room to let the robot enter, it went around clockwise, but the communication was interrupted at the manhole located at the South-East of torus room.

The robot is cabled, Tepco hasn’t verify the cause yet. They only assume the cable might have been damaged on the way. Tepco can’t take the robot back either because the radiation level is too high.
The robot sent radiation and visual data until it stopped but because the sound data is recorded in it, it can’t be obtained until they get the robot back. They were planning to detect the water leaking point by recording the sound data.
They recorded the sound data when they conducted robot survey in torus room of reactor2 as well, but because the alarm of survey meter was too noisy, they couldn’t hear the sound of water flow.

Obtained data will be published tomorrow.
