Nov 07, 2018 (Japan Times) - Tokyo Electric Power Company Holdings Inc. has launched an English-language online virtual tour of the interior of the crippled Fukushima No. 1 power plant, allowing website visitors to check the progress of decommissioning work following the 2011 meltdowns --- one of the world's worst nuclear crises.
Inside Fukushima Daiichi offers views of 10 routes within the six-reactor plant’s premises, which are separated into red, yellow and green zones according to the degree of radioactive contamination.
Workers within the red zone --- which includes the crisis-hit reactor buildings --- must wear protective clothing and full-face masks, but can wear regular uniforms while in the green zone that makes up a large part of the premises.
More than seven years after the nuclear fuel meltdowns at the complex, triggered by a major earthquake and tsunami, images show a barrel-shaped cover structure on top of the No. 3 unit, which suffered a hydrogen explosion that blew off the roof off of the building.
The website also offers close-up images of scarred walls with wires hanging from the side of the No. 3 reactor, as well as people in protective gear working at various locations.
Viewers can take a tour up to the entrance of the containment vessel of the No. 5 unit, located on higher ground and unscathed by the tsunami. It has a similar structure to the affected units.
Radiation levels in each area, measured this March, are indicated on the side of the screen as visitors follow the virtual tour of the facility.
