[Video] Tepco investigated the inside Reactor 3 vessel / 1 Sv/h, “sediment” accumulated

(Before It's News)

According to Tepco, they implemented the first investigation of Reactor 3 PCV (Primary Containment Vessel) on 10/20/2015.

They installed 2 types of cameras, dosimeter and thermometer from the penetration hole called X-53.

As a result, the atmospheric dose was 1 Sv/h above the retaining coolant water. They gave up investigating the bottom of PCV. Tepco comments the sediment was accumulated between the wall of PCV and the grating part to stop the camera moving toward the bottom.

The sediment is not identified.

Tepco reported the water level was 6m from the bottom, which was approximately what they simulated. The water temperature was 33~35℃. No significant damage was observed.
