3 reactor building of the Fukushima No. TEPCO will use the drone to examine the location of scattered debris and the level of radiation inside the reactor building, among other things. The drone will check areas including the building’s third floor, which has not been sufficiently monitored because radiation levels are too high. According to TEPCO, key equipment such as that used to cool spent nuclear fuel pools are located on the third floor. Combining these images with measurements of radiation levels allows for the production of maps outlining contamination levels inside the reactor buildings.
