Tepco uses underwater robot to probe inside damaged Fukushima nuclear reactor

The sights of Fukushima exclusion zone

An underwater robot has begun probing the inside of the badly damaged Fukushima nuclear power plant in Japan.

The exact location of a large amount of melted nuclear fuel debris inside the No. 3 reactor, one of three which underwent core meltdowns in the 2011 quake and tsunami-triggered disaster, which knocked out the plant's key cooling and backup systems, remains unknown.

Depending on the data collected from Wednesday's expedition, another mission with the drone, dubbed 'Little Sunfish, ' will be launched Friday to delve even deeper into the containment vessel, reports

Unit 3 is one of three reactors that suffered meltdowns following an quake and tsunami in 2011. It will travel to the bottom of the containment vessel, where the deposits of melted fuel debris are assumed to have accumulated.

The investigations follow robot probes in the plant's No. 1 and No. 2 reactors, which were conducted from January to March. Officials said tritium is relatively harmless in smaller doses, but local activists and fishermen have lamented what they say will be a further negative perception of the country's environmental situation after experiencing the world's worst nuclear disaster since the 1986 meltdown in Ukraine's Chernobyl, which is still largely off limits to the general public.

The camera-equipped robot captured images of the collapsed scaffolding after moving forward to the opening of a tube-shaped concrete object that supports the pressure vessel.

Experts believe that melted fuel has breached the reactor core, falling to the bottom of the chamber where it is submerged by 6m (20ft) of highly radioactive water.

Currently, water levels inside Unit 3 are higher than levels in the other damaged areas, which is why technicians chose to deploy the Little Sunfish inside that unit, Japan Today reported.

The cost of TEPCO's more than six-year-long cleanup process was doubled to a staggering $188 billion last year, and its agenda remains severely behind schedule.
