So apparently the Robots trying to clean up Fukshima are getting their IC’s fried by radiation.
One of the problems is that they are using tethered robots trailing power / control cables behind them that keep getting snagged in debris so it takes a long time to navigate to get to where the fuel rods are located. Another article I read mentions the robots had to be able to open doors to navigate through the building.
Question, why wouldn’t you just first use robots with water cutters or thermal lances to cut right through walls to make a straight line path to areas of interest? Then use debris clearing robots to pick up fragments and make a clean clear path? If they’re worried about releasing radioactive debris from cutting through walls they could erect an outer containment shell first. And surely they know which parts are load bearing and which aren’t and could pick a safe straight path through the building.
Side question, they mention millions of gallons of radioactive water being stored on site. This is generated from pumping the water through the melted down reactor to cool it. What sort of half life would the radioactive water have after that? How long until its safe to release back into the sea?
EDIT: yes yes, user name, post combo
