WORKS ON THE INSTRUMENTAL DIAGNOSTICS OF THE ANPP REACTOR VESSEL HAVE BEEN COMPLETED

The Croatian company “INETEC” has completed the instrumental diagnostics of the reactor vessel of the Armenian Nuclear Power Plant (ANPP). Within the established timeframe, an instrumental inspection of the reactor vessel’s base metal and weld seams was carried out using non-destructive testing methods based on three techniques:

         •          ultrasonic testing,

         •          eddy current testing,

         •          visual inspection using cameras.

During the instrumental diagnostics of the reactor vessel, seven weld seams, the base metal, and cladding along the entire length of the reactor were inspected. Eddy current testing of the spiral holes of the reactor’s main flange connection was also performed. Additionally, 100% eddy current testing of the heat exchange tubes of the first circuit of the steam generator was ensured, and the identified defective heat exchange tubes were plugged.
