Inside a Fukushima reactor: How VR gave me a scary-real expertise

I am inside one of the reactors at Fukushima Daiichi Nuclear Energy Plant, website of the worst nuclear catastrophe in historical past. It is pitch black, with solely a flashlight to mild my means. I glide over a steel catwalk, heading deeper into the reactor.  However then, after I flip to stroll down the steps, I hit an obstruction.

At that second, a loud buzzer, like one thing out of an outdated recreation present, blasts into my ears, breaking the entire phantasm.

Fixing Fukushima

Fixing Fukushima is a CNET multi-part sequence that explores the position know-how performs in cleansing up the worst nuclear catastrophe in historical past.

OK, so I am not really within the Unit 1 reactor at Fukushima –- the radiation degree at its core is excessive sufficient that even minutes inside can be a demise sentence. I am in a digital actuality setup on the Naraha Middle for Distant Management Know-how, a few half-hour drive south of the Daiichi facility.

Subsequent to me are my photographer, an interpreter, a consultant from Tokyo Electrical Energy Co. and an worker of the Naraha facility who’s serving as our information via this digital re-creation. We’re all looking at a large display projected on the wall just some ft in entrance of us and to our sides.

Because of robotic surveys and a great deal of information, this facility has been capable of piece collectively a reasonably correct simulation of the Fukushima reactors. Tepco and the Japan Atomic Power Company have labored collectively to construct this setup. However not like different VR experiences, the digital journey into the ability is not for enjoyable. Teachers, engineers and Tepco staff use these simulations to get a way of what sorts of robots could make it via the reactors, and which may’t.

Eight years after an earthquake and tsunami mixed to overwhelm Fukushima Daiichi, the plant stays shut down, with Tepco and the Japanese authorities struggling to search out methods to take away the radioactive materials.

Inside Fukushima: Standing 60 ft from a nuclear catastrophe


This VR simulation marks one technique to expertise how unhealthy issues are inside — with out the fee and danger of really coming into the reactors. Digital actuality will get a nasty rap lately as a much-hyped know-how pattern that didn’t captivate customers in a significant means. There are choose cases that transcend the standard expertise, from a mash-up of VR and immersive theater to initiatives that faucet into your feelings, however for essentially the most half, many customers (and a few CNET editors) have knocked VR as too costly and never dazzling sufficient to be value your time.

However the Fukushima expertise illustrates how VR can transfer past leisure and serve extra sensible wants. By providing a way of what it is really like inside these reactors, it is serving a vital position within the mission to decommission the reactors at Daiichi, a job that is estimated to take 4 many years and $75.7 billion.

“We consider that testing a developed know-how … by utilizing tools much like the true one earlier than making use of the precise facility, will make the development on website extra possible,” says Hideki Yagi, basic supervisor of Tepco’s Nuclear Energy Communications Unit.

Gliding via a reactor

In contrast to a typical digital actuality setup, which requires you to put on a big, cumbersome headset that closes you off to the true world, the Fukushima expertise encompasses a pair of 3D glasses.

Digital projection provider Christie Digital Techniques created the screens, which span your complete peak and width of the wall, or almost 12 ft every means. The display extends to the left and proper sides, which go about seven and a half ft again. There are 5 projectors hidden behind the screens, together with one which shoots from above right down to the bottom beneath me.

The huge show, which provides a full-scale rendering of the ability, totally immerses you within the place. Whereas nobody would get into specifics concerning the price ticket, Mike Garddio, a senior undertaking supervisor at Christie, says one thing like this prices lots of of 1000’s of .

“It isn’t one thing you will discover at your native arcade,” he says.

The rendering was put collectively via a mix of current blueprints and laser mapping generated from information amassed by survey robots despatched into the reactor buildings. As we get deeper into Unit 1, the main points fade away, since nobody actually is aware of what’s contained in the core of the reactor and beneath, known as the first containment vessel and the pedestal.

Itochu Techno-Options designed the person interface and utility, which included information from the JAEA and Tepco. The system consists of information from Items 1, 2 and three at Daiichi, which all nonetheless have various levels of radioactive materials and particles caught of their cores.

“The accomplishment of this undertaking was based mostly on the know-how developed by offering simulation options within the engineering space, and due to assist from JAEA and nuclear energy-related firms concerned in Fukushima reconstruction,” says Jumpei Asano, a spokesman for Itochu.

In our first run-through of the Unit 1 reactor, our information was in management, wielding a one-handed controller that seemed like a cross between an influence drill and a phaser from Star Trek. As a result of Tepco needed to maintain the main points of the reactor a secret, we could not movie any of the footage.

After gliding via the reactor for a short while, our information switches from simply the flashlight to full lighting, giving us a greater view of our environment. That preliminary flashlight view was essential, although, because it provides operators a greater thought of what the restricted view appears to be like like.

The expertise is convincing sufficient that I really feel a tingle in my physique as we run via a wall. Our information takes us up and down totally different elements of the reactor, which is a bit disorienting since your physique is aware of you have not really moved.

The display’s orientation is tethered to the information via a motion-tracking system connected to his 3D glasses, basically making us passengers on his wild journey.

Getting into the Matrix

After a couple of minutes of the guided tour, I don the primary 3D glasses and seize the controller for my very own journey.

For safety causes, the Naraha operator loaded up a mock simulation of a generic reactor house, permitting me to cruise round at my leisure.


Kuniaki Kawabata, precept researcher for distant management know-how on the JAEA, stands by a warning message. Due to the accuracy of the simulation, we weren’t capable of take images of the expertise.

VR is commonly in comparison with The Matrix, and I discover the comparability apt with this technique. The flooring are white with a grid of black strains, and a grey construction homes an assortment of pipes I can navigate via. It is all very colorless.

I can go ahead and backward on the push of a button, and may flip or transfer up and down by transferring my head in that course. The expertise is loads smoother now that I am in management, the display and controls in sync with the place I need to go.

A second button permits me to “grip” objects within the digital world and produce them across the house. If the thing does not match via the pipe, I hear that buzzer.

My expertise is not precisely a tour of one of many Fukushima reactors, however it does supply me a glimpse at how such a software might assist practice operators to pilot a robotic via the true factor.

That is a heck of much more helpful than some gimmicky VR stunt tied to an upcoming film.
