Today, the Japanese company Toshiba has notified users about its new offspring – it is a special diagnostic robot designed specifically to examine and study the second damaged nuclear reactor of the Fukushima-Daichi reactor system, which suffered during the 2011 tsunami in Japan. Work on the elimination of nuclear waste and other fragments is still ongoing and according to the statement of authoritative experts in this field, it will continue until 2021. That is why Toshiba introduced a new model of its robot on four legs, whose main goal is to identify the necessary technologies necessary for the “cleaning”.
It is worth noting that Toshiba has previously proposed various solutions for the dismantling and decommissioning of the Fukushima reactor complex – in 2012, it introduced and launched a robot for the same diagnostic purpose in relation to the first nuclear reactor, and in 2016 designed a remote control robot that carried out separation and decomposition of fuel rod assemblies from one reactor to another – which is an extremely important step in the complete deactivation of a nuclear reactor even some time after the disaster.
It is worth noting that the tsunami itself that occurred in Fukushima in 2011 was, in turn, caused by a significant Tohoku earthquake – and therefore most of the work to deactivate reactors is carried out at shallow or great depths, where it is first necessary to separate the fuel rods from main system to prevent further potential problems. In addition, Toshiba says that another interesting and useful robotic project is brewing within its walls.
However, it is too early to say what exactly it will present and offer to end users – there may be many points and features associated with the correct distribution and preparation of technologies. So far, it remains to wait for the first estimates and results on the diagnostic mission of the current robot, which has 12 inches in length and which will mainly work at a shallow depth to identify various problems.
