The evaluation showed that the giant main arm of the robotic system could handle a payload of 60 tonnes with exceptional precision, achieving accurate positioning and vertical lifting to within 4mm (0.2 inch).

Every component that this interacts with is going to have to be designed to compensate for this absolutely atrocious positional accuracy. You can’t have 4mm of slop in a godsdamned nuclear reactor, and the inherent inaccuracies of arm-based systems like this are the exact reason every other nuclear facility (including china’s) uses remote operated cable-hoist systems (usually overhead cranes) for material handling. I have absolutely no idea why they’re bragging about this one, it’s a terrible solution and has been for decades.
