POLICY. made it virtually impossible to design a plan to get rid of this nuclear waste. Humans naturally could not enter these lethally radioactive reactors, so efforts to look for this missing fuel relied on robots. However, for years, robots had failed in this mission— blocked by debris or disabled by radia- tion that ruined their electronics. In 2017, researchers f inally dis- covered the fuel using a submers- i ble r ob o t c r e a t e d by To s h i b a Corporation and Japan's International R e se a rc h In s t it ut e for Nuc le a r Decommissioning. Named the Mini- Manbo, or "little sunfish," the under- water remotely operated vehicle (ROV) was roughly 13 centimeters wide, 30 centimeters long and 2 kilograms in weight, with electronics hardened against up to 200 sieverts of radiation. (A dose of one sievert is enough to cause radiation sickness in a human.) The robot used five tiny propellers to hover and glide through the water pumped into the Fukushima's Unit 3 reactor building to cool it down after the disaster. The ROV was just small enough to fit through the roughly 5.5- inch hole leading into the unit's pri- mary containment vessel. Equipped with front- and rear-fac- ing cameras and LED lights, the robot delivered a video feed to its operators. Powered and remotely controlled via wire, it took three days for the robot's operators to navigate it through the Unit 3 reactor building to the reactor itself. There, it transmitted video of a hole at the bottom of the reactor, and the melted uranium fuel on the f loor beneath it. The researchers later had similar successes at Fukushima's other two ruined reactors. Japan is now "developing systems like RadPiper to enter internal spac- es like piping," Rimando said. "Our work with RadPiper could help sup- port later decontamination efforts at Fukushima." RADPIPER " Y S E ANYWHERE FROM $10 MILLION TO $50 MILLION PER FACILITY."
