Tepco releases first images of Fukushima reactor 3’s containment vessel: Fox News Latino; The Asahi Shimbun

Fox News Latino:

” The operator of Japan’s troubled Fukushima nuclear power plant has released the first pictures of the interior of reactor 3, thanks to two cameras that revealed a substance that could be melted nuclear fuel.

Tokyo Electric Power, or TEPCO, technicians introduced the cameras through a pipe, along with a thermometer and a measuring device, into the reactor’s containment vessel to assess the state of the nuclear fuel.

Radiation levels were recorded at about 1 sievert per hour – more than 1 million times the maximum recommended level – inside the vessel, while the temperature was between 26 C and 27 C above the ambient temperature, TEPCO said.

The radioactive water at the bottom of the vessel is 6.5 meters (21 feet) high, in line with technical estimates, and has a temperature of about 33-35 C.

The video and photographs taken by the remote-control operated cameras did not confirm damage to the containment vessel caused by molten nuclear fuel.

One of the cameras showed sediment similar to mud, which could be melted fuel.

TEPCO is expected to take water samples this week to analyze the concentration of radioactive substances.

An earthquake and tsunami in northeastern Japan on March 11, 2011, killed 15,853 people, left 3,282 others missing and damaged the Fukushima nuclear power plant, causing the worst nuclear accident since Chernobyl. EFE ”

The Asahi Shimbun:

” More than four years after the triple meltdown, Tokyo Electric Power Co. on Oct. 20 got its first look inside the containment vessel of the No. 3 reactor at the Fukushima No. 1 nuclear plant.

Images from an industrial endoscope inserted into the containment vessel along a wall confirmed no damage to pipes and other equipment, according to TEPCO.

The early survey results for the days-long study also found radiation levels inside the containment vessel were 1 sievert per hour, a reading too high for humans to work there.

TEPCO also said 6.4 meters of water had accumulated on the bottom of the containment vessel, which was in line with the utility’s estimate.

Water temperatures were 33 to 35 degrees and air temperatures were 26 to 27 degrees inside the vessel, according to TEPCO.

The survey is being carried out to prepare for the eventual extraction of melted fuel from the containment vessel.

TEPCO carried out endoscope surveys at the containment vessels for No. 1 and No. 2 reactors in 2012. The radiation level at the No. 3 reactor was lower than those at the No. 1 and No. 2 reactor buildings. ”
