Robot begins removing Fukushima nuclear plant’s melted fuel.
Robot begins removing Fukushima nuclear plant’s melted fuel.
Nuclear fuel in the reactor cores melted after the magnitude 9.0 earthquake and tsunami in March 2011 caused the Fukushima Daiichi nuclear plant's cooling systems to fail
You're viewing a single thread.
A sincere question: why they don't place some relay/repeater for the robot's signal so they could control it from anywhere in the world through internet (or even some very private wireless communication network, outside internet due to security concerns)? The fact that they have to switch personnel every 15 minutes is a sign that they're doing this in situ, rather than remotely.
Drones with mobile network connectivity are already a thing, for example. If you consider that internet exposure is dangerous (connection could be hacked, etc), ham transceiver repeaters are also a thing, and you can even chain many of them across many kilometers. It's called mesh network.
Highly Radioactive situations and nuclear applications in general cause great trouble with any digital device, let alone complex Wireless communication, due to the fact that the particles being emmited can flip bits on your Microprocessors and make the whole thing break down. Fully analog devices are used for control applications in nuclear plants for that reason, there is likely something like that going on with this setup
Ah, got it. Thanks for the reply!
