Technical support was provided during the coordination of the corrected technological documentation for the repair of the main connector of the WWER-440 reactor vessel in the DIARU. Developed and proposed technological process of repair surfacing allows to remove the heat treatment of the reactor vessel and cover WWER-440 after repair, which is very important and relevant for the safe operation of the first and second units of Rivne NPP.
