Following on the footsteps of the latest two successful Russian EVAs (VKD-56 and -57), which installed the missing major elements on Nauka that were launched with Rassvet during STS-131, the ShK airlock and the RTOd radiator through the help of ERA, this spacewalk will aim to complete major work on the radiator, by filling it with coolant and deploying it to its working configuration in order to support full heat rejection capability in the RS. The coolant is now contained in Nauka's storage tanks as launched, and will be transferred through a fluid control panel on its side hull.As a secondary task, while the radiator fills up, they are expected to install a couple of gap-spanners on ERA's main booms to allow for easier EVA access along the arm.This EVA should complete the major external configuration changes in the RS, in general or until a further expansion (involving NEM?) takes place, except for future external experiment packages and their support structures.

They are using an expendable tank to fill the radiator which will be jettisoned afterwards. After filling it will be connected via valves to the Nauka cooling system loop.

I was going by the video summary, but perhaps I misinterpreted something? Where's the container now? Isn't it hazardous to have it inside if that's where it is? Did it come up in a Progress?
✨ Today we go into outer space again!This time it will be difficult to oversleep the beginning of the exit Join the evening "space walk" on May 12 at 18:45 Moscow time! It's a great time to spend it in the company of Roscosmos cosmonauts and the hosts of our broadcast.Sergey Prokopyev and Dmitry Petelin will have to deploy a radiator on the Nauka module. The planned duration of the work is 6 hours 18 minutes
... Friday, May 1211:30 a.m. - NASA TV coverage begins for a spacewalk to deploy a radiator on Nauka and connect mechanical, electrical, and hydraulic lines.The spacewalks will be the fifth and sixth for Prokopyev, who will wear the Orlan spacesuit with the red stripes for all of the spacewalks and the third and fourth for Petelin, who will wear the spacesuit with the blue stripes....
