There have been deviations no nuclear and radiation standards occurred because of the breakdown at the substation with 110 kW voltage of the Armenian Nuclear Power Plant, as Chairperson of State Committee on Nuclear Safety adjunct to RA Government Ashot Martirosyan told EcoLur. The breakdown occurred on 21 January.
According to Ashot Martirosyan, the breakdown was caused with the melting, 'As the water was cold, there were frozen parts on the 110 kilowatt voltage lines. The weather got better and melting started, which led to short circuit and breakdowns, which resulted in the decrease of the magnitude of the power station up to zero. The nuclear power station hasn't shut down: it has remained on zero magnitude. After eliminating the breakdowns of high-voltage wires, the increase in nuclear power station magnitude was kicked off in line operational regulations. There have been no deviations recorded both in radiation and nuclear safety,' Ashot Martirosyan said.
In reply to EcoLur's question whether the action plan on nuclear power station lifetime extension includes damaged infrastructures Ashot Martirosyan said, 'Yes, the action plan on nuclear power station lifetime extension includes measures aimed at modernization of substations with 110 and 220 voltage. The breakdown occurred in the substation, i.e. in the area, which is located in a distance of around 100 meters from the reactor and other equipment. This substation transfers the electricity produced by the nuclear power station to the energy system of Armenia. It means there have been no drawbacks in the turbine, reactor and other technological systems of the nuclear power plant.'
