Kursk, May 3 - Neftegaz.RU. On 29 April, 2018 at the construction site of Kursk NPP-2 the first cubic meters of concrete were poured in the bed plate of the power unit No 1 reactor building. Thus, the main construction works have started, and the construction of Russian most powerful power unit of 3+ generation with electric power of 1,255 MW has begun.
The power units No 1 and No 2 of Kursk NPP-2 of 3+ generation are the pilot units that are being constructed upon the VVER-TOI project. This is the new project created by the Russian designers on the basis of the technical decisions of NPP with VVER-1200 reactor project.
The nuclear power plants of 3+ generation have improved technical and economical indicators. Thus, in comparison with the power units of the previous generation (VVER-1000) the unit’s power increased by 25%, up to 1,255 MW. The main equipment’s lifespan increased twice (from 30 to 60 years, with the possibility to prolong it up to 80 years).
Owing to the high level of automation the number of personnel is reduced by 30-40%. In comparison with other power units of 3+ generation (power units No 1 and No 2 of Novovoronezh NPP (No 2 is being constructed) and No 1 and No 2 of Leningrad NPP (No 1 is at the power testing stage, and No 2 is being constructed) it is intended that the VVER-TOI project will have the reduced construction value, terms, and operations costs.
New power units of Kursk NPP-2 meet all the modern requirements of the IAEA in the field of safety. A number of the up-to-date safety systems were applied: the reactor core melt trap and the heat removal passive system that allows to cool the reactor core in the absence of the power supply at the expense of the natural air circulation.
As compared to the already constructed power units of 3+ generation in the VVER-TOI project a number of the additional safety precautions were implemented. Thus, the power unit is expected to stand the earthquake of magnitude 8-9 as to magnitude 7 in the NPP with VVER-1200 reactor project.
The Deputy Director General of Rosenergoatom, the Manager of Kursk NPP Branch Vyacheslav Fegyukin: «VVER-TOI power units are the most advance products in the area of the high nuclear technologies. Not only the future of Kursk NPP, but also the future of Russian nuclear power industry in general is connected with them. These power units must become the benchmark and one of the series for the construction in the international projects. Kursk NPP-2 is one of the priority projects for Rosenergoatom and the industry in general. One can assess the scale of the construction by the amount of investment: in 2018 more than 27 billion rubles will be spent at the Kursk NPP-2 construction; this is 10 billion more than in 2017.»
