The delegation included representatives of the companies participating in construction of Finnish Hanhikivi 1 NPP together with JSC CONCERN TITAN-2.
Scheduled testing of the internal containment of the reactor was performed by AtomTechEnergo company. During the first testing stage the containment was vacuum pumped, followed by a sonic and visual test of the reinforced concrete structure. Tests proved air-tightness of the containment.
During second stage compressed air was fed into the containment in order to create the necessary pressure level, confirming tightness of the reactor containment.
Finnish experts were interested in the testing procedure, as well as the test results. In future they will use this experience in construction of Hanhikivi 1 NPP.
