EVA likely Nov 1
I have talked with Robert Navias today at Baikonur cosmodrome about EVA-20. He said that ammonia leak is from forward radiator. So astronauts during spacewalk should install jumpers for by-passing this radiator and for a connecting aft radiator, which will be deployed. If I have understood him correctly, they will not re-fill PVTCS 2B by ammonia from EATCS in EVA-20. Also Rob has told that the leaked radiator can be replaced in future by spare radiator, for example, from ELC-4.
So what is here the aft radiator will be deployed again.
Do we have a document on L2 that can provide detailed information on the plumbing that supports the P6 radiators?

That is correct, although I don't think we can really call it the aft radiator anymore, since the P6 Truss now rotates along with the SARJ, and so what is aft will change periodically to forward/nadir/zenith.
So this EVA is a temp bypass of the main system until a new radiator can be installed?
