ArmInfo. On May 10 Armenian NPP will be removed from electric power grid to carry preventive maintenance work and refueling operation, Armenian Ministry of Energy Infrastructures and Natural Resources press-service informs.
According to the source, in parallel with the implementation of preventive maintenance work, events' implementation will continue within the program to extend the life of the power unit N2. According to the schedule, the unit will be connected to the network on July 9.
The Ministry reminds that the stop of the unit is presupposed in the balance of energy generating and does not affect the tariff.
Earlier, during the interview with ArmInfo's reporter, the head of the project on N2 exploitation energy unit prolongation of Armenian NPP Vladimir Bredov stated that a considerable amount of work would be carried out during the preventive maintenance. The main focus will be put on the safety of the nuclear power plant: works related to the repair of equipment will be performed, as well as work on instrumental inspection of equipment. The repair of the equipment will be assisted by employees of the Kolskaya and Novovoronezh nuclear power plants - they are the ?twinning? stations of the Armenian NPP, scientific management will be carried out by JSC TsNIITMASH, an industrial enterprise of the Rosatom. As for the instrumental survey, the main task of this exercise is to calculate and confirm the residual life of the equipment using non- destructive testing methods. In simple words, it is necessary to check the possibility of further operation of NPP equipment. As you know, there is a lot of equipment on the NPPA, so the instrumental survey is distributed for several years, without compromising the safety and operation of the NPPA. Last year, we started this process; this year the volume of the surveyed equipment increased by 50% compared to last year (150 types of equipment) at the request of the supervisory authority. We hope to finish the instrumental survey process next year and in 2019. Transfer calculations and conclusions to the supervisory authority - the State Committee for Nuclear Safety Regulation. We hope to finish on time, but everything will depend on the results of the survey and the decision of the Gosatomnadzor.
