Seta’s armenian blog armenian news… a topalian… pm calls for end to civil actions electricity transmission vs distribution

Commenting on this statement of the Prime Minister, Deputy Director General of Armenian NPP CJSC, Director of the program for extending the life of the second power unit of the Armenian NPP, Hera Sevikyan stressed that the issue with the construction of the new unit is not new. The station has all the necessary infrastructure – a platform, water, personnel, the problem is only the power of the new unit and its type. The construction of a block with a capacity of 1200-1500 MW for Armenia is unacceptable, since in the absence of the necessary volumes of consumption this can lead to the destruction of the entire energy system of the country. The optimal option would be a 540-600 MW unit, but the problem is due to the lack of these units in operation, and Armenia has chosen a policy of using exclusively reference stations. Also, during the discussions there are variants of the block with a capacity of up to 40 MW, but in this case 12 modular nuclear power plants will have to be built to compensate for the capacities of the operating unit, which is also a problematic task. "Yes, and with fuel for these types of reactors can be difficult," – said Gera Sevikyan. In addition, he continued, it is necessary to retrain personnel for work on such units, which is a very expensive activity, as the personnel of the ANPP is accustomed to working and familiar with the WWER reactor.

Reactors of small and medium power, from 30 to 300 MW, so-called modular reactors, can come to replace not only classical atomic units, but also thermal generation units. Today, according to IAEA estimates, there are 50 projects and concepts of small and medium-sized reactors in the world. They can be both stationary and mobile. Moreover, both terrestrial and marine installations are developed, which can be controlled from the shore remotely. Among the countries developing these technologies, besides the United States, Japan and North Korea, are also Canada, France, China, Russia, India, Argentina and South Africa. In addition, in Argentina, China and Russia is already building a completely different technology for the installation. The idea to build independent modular reactors was fixed in the world in the early 2000s. However, then they were considered mainly as reserve sources for developing countries, as well as for remote settlements, production and mining complexes. That is, places where it is difficult to stretch electrical networks. Today these projects are considered as independent generation complexes for any places, including densely populated ones. The concept of their development is based on the policy of decentralization of production and supply of electricity. Unfortunately, giant energy projects have become very vulnerable. Any natural disaster or hacker attack can disable large stations – and millions of people in a moment will be left without electricity. But local stations reduce such dependence and suffer less from natural disasters, since they have tightly closed internal infrastructure. Due to their size and locality, modular reactors are much safer than larger nuclear power plants. The second Chernobyl will not be on them, because other technical solutions are involved in modular reactors.
