On 7/24/2013, Tepco conducted the second thermography survey of the operation floor of reactor3, where the steam was observed.

The surveying time was 4:40 ~ 6:04 AM. They conducted the first thermography survey on 7/20/2013 but because the surveying time was from 12:39 to 14:40, sunshine distracted the details. (cf, Thermography shows 50℃ on operation floor of “steaming” reactor3 [URL 2])

This second thermography survey showed the steaming area is about 34.3℃, where the atmospheric temperature was 18.6℃.

It was surveyed at 5m above the floor.

Around where they detected over 1Sv/h, the temperature was 24.7℃, which was also higher than back ground. However, it was surveyed at 40m above the floor. Details are not clear. (cf, Reactor3 steaming again / Over 1 Sv/h at 6 of 25 locations on the operation floor [URL 3])
