ArmInfo. The stop of the second power unit of the Armenian Nuclear Power Plant for scheduled preventive repairs is scheduled for May 15, 2020 and will last 65 days. Hakob Vardanyan, Deputy Minister of Territorial Administration and Infrastructures, told reporters about this on November 10 during a visit to the ANPP.
He stressed that as part of the preventive work, the introduction of security systems of various levels is expected, as well as the construction of a new open distribution substation, since the existing one was built in 1974-76.
In turn, the ANPP Director General Movses Vardanyan noted that in the coming year a study will be carried out on the condition of the reactor vessel, which is carried out every 4 years. The last time such a study, he emphasized, was conducted in 2016. According to Vardanyan, in the next two, work will be completed on the development of a large-scale simulator for the Armenian nuclear power plant, which is carried out with US support. <At the moment, we are negotiating with American partners to get the rest of the funds. If US assistance is not satisfactory, then I believe that we will replenish it with our own resources and complete the work in the next 2 years, in particular, we will increase the level of safety of nuclear power plant operation, and we will be able to retrain personnel more quickly, "he said.
Earlier, Director General of the Armatom Research Institute Vahram Petrosyan reported that work on a large-scale simulator was carried out with the assistance of the US Department of Energy. Its need was determined by the demand of the time and aimed at improving the professional skills of the Armenian NPP employees. He emphasized that if such Chernobyl NPPs were used simulators, tragedy could have been avoided, since the experiment would have been carried out not on the reactor itself, but on the learning device.The professor also announced the launch of repair systems the fourth-generation simulator, the main purpose of which will be training and retraining of repair and maintenance personnel of the ANPP, information support during the operation and repair of plant equipment, improving the technical knowledge of personnel and improving working conditions.He also noted that the Armenian safety systems at nuclear power plants were interested in Uzbekistan and Bangladesh, where new nuclear power units will be built, and American dealerships interested Equipment for nuclear power plants. According to the professor, the institute has developed sensors that detect the slightest fluctuations in steam generators. "We produced 74 of these sensors for the Armenian nuclear power plant. Thanks to this, in 2018, an accident was recorded on one of the steam generators where the engine oil was leaked," added Vahram Petrosyan.
The Armatom Institute was created in 1973 before the commissioning of the first block of the ANPP (1976). The Institute conducts studies of the technical condition of nuclear power plants and develops new devices for its safety. In particular, in 1989 the institute developed one of the first simulators in the USSR for the personnel of nuclear power plants, which was installed at the Novovoronezh NPP. The Institute also developed and implemented the fourth generation industrial antiseismic protection system (SIAZ).
