You are describing "dry" annealing there. This has not been applied anywhere, as it requires removing and reinstalling the internal support structures inside the reactor vessel.
A somewhat lower temperature "wet" annealing process has been applied to two test reactors. I don't think it's been applied to any full scale power reactors.

- jabl 1y agoThis was AFAIU a 'dry annealing' on a full scale power reactor: https://inis.iaea.org/records/505bf-gcq02 https://inis.iaea.org/records/505bf-gcq02 and https://inis.iaea.org/records/a42j1-np856 https://inis.iaea.org/records/a42j1-np856 Not the whole reactor vessel though, just one critical circumferential weld seam. (As mentioned in the second link, other VVER-440 reactors had previously been annealed, I'm sure one could find information about them as well.)
