The work was done in full compliance with the time schedule and quality requirements. The Armenian NPP is a key power generator accounting for 40% of total power output in the country. Pursuant to the framework agreement between Russia and Armenia, a contract was concluded between the Armenian plant and Rusatom Service to assess the reactor’s condition after long-time operation and perform repairs. Earlier this year Rusatom Service selected the Central Research Institute for Machine Building Technology as a general contractor and a single service provider under this contract. In its turn, the institute subcontracted RosEnergoAtom, OKB Gidropress and ECHO+ to deliver the project. Up to 40 employees of the subcontractors were simultaneously working on the customer’s site. The Central Research Institute for Machine Building Technology developed technical documents for the project, procured and supplied welding materials and equipment, provided technical staff, and, in association with ECHO+, performed non-destructive testing on the reactor systems.
