ArmInfo. As part of the program to extend the life of the N2 power unit of the Armenian Nuclear Power Plant in 2017, over 690 units of equipment were inspected.
According to Artem Petrosyan, Head of the Department of Atomic Energy of the Energy Ministry of the Ministry of Energy Infrastructures and Natural Resources of the Republic of Armenia, 37 programs were developed within the framework of the surveys and 127 conclusions on the justification and technical condition of the main systems as well as the residual resource of the block were issued.
Technical tasks on modernization of emergency core cooling systems, reliable power supply of the unit, transformer of the unit, as well as the so-called sprinkler system were approved.
In the specified time, the delivery of equipment subject to modernization began. The first of two turbo- generators, cooling pumps, part of the equipment for overhead cranes, and the other part will be delivered to the nuclear power plant site by the end of this year. According to Artem Petrosyan, replacement of the main equipment will begin in 2018 during the planned preventive maintenance.
Earlier, in an interview with ArmInfo, Deputy General Director of Armenian NPP CJSC Hera Sevikyan noted that in April 2018 the plant's reactor will be stopped for two months. At the same time, turbines alternately stop for six months. First, the first turbine will be replaced, which, after modernization, will begin to work, and then the second one will be stopped. "Thus, during the whole period of work, except for two months, when the reactor is shut down, the unit will produce electricity, perhaps even in the amount of 60%, providing about 200-220 MW of electricity," the expert noted.
As for the power generation systems, as Hera Sevikyan noted, the station has ambitious plans for this component. The whole cycle will be almost completely replaced, starting with turbines, generators, and ending with capacitors, transformers and cooling towers, which will be modernized at the modern level. As a result, the efficiency of nuclear power plants will be significantly increased. "Based on the experience of other countries, we expect that the efficiency will increase by 18-20%, the capacity of each turbine will increase to 226 MW, and this will be done without additional fuel consumption,".
