“Nowhere in the world build not a single station on a project, similar Laes-2, from point of equipment such additional systems of safety”, - the main engineer of project Alexander Kazarin underlined. New power units possess unprecedented measures on providing

planned on June, 16, 2009, Center of public information of Leningrad AES reports. With what goes to the public listening of genproektirovschik and general contractor Laes-2 – Saint Petersburg nauchno-issledovatel’skiy and proektno-konstruktorskiy institute "ATOMENERGOPROEKT",
the main engineer of project Laes-2 Alexander Kazarin told in detail. According to him, between the first and second turns of Laes-2 there will be small distinctions."From point of power units – reactor setting, turboustanovki and basic technical decisions
– it, sure, ob’ekty-analogi, but differences will be all the same. For example, we suppose for the second turn to use two cooling not towers on power unit, but one", - A.Kazarin reported. The leaders of atomic industry ground the choice of power unit with Vver-1200 (vodo-vodyanoy
power reactor by power 1200 megawatt) as a basic project of development of atomic energy of Russia on the nearest prospect. The reactor setting of Vver-1200 is based on those principles, what Vver-1000. In the USSR, since the seventieth years of the pas
centuries, with an interval in one year the series of power units were built with these reactor settings: on Novovoronezhskoy, by Zaporozhia, Rovenskoy, Khmel’nickoy and Yuzhno-ukrainskoy of AES. Then power units with Vver-1000 were allowed on Kalininskoy and Volgodonskoy And
Last years two such power unit were built and put into an operation on Tyan’van’skoy of AES in China, and two power units are built on AES "Kudankulam" in India. All experience, accumulated here, will be realized in a project Laes-2. Construction of technological
systems of the station is in a great deal based on the before accepted decisions. For example, a construction of four ductings of the systems of safety is a decision, approved on Tyan’van’skoy of AES. Addition of the passive systems, approved at development of project Vver-640, – it that,
that yet more advantageously distinguishes a project Laes-2 from a project Tyan’van’skoy AES from point of safety. AES of high-powered is claimed in countries with the developed and strong grids – for example, in France. In Russia a grid as yet is more weak, building
power units of high-powered a few remote future is business. True, in 2006 a so urgent base project AES was developed with the reactor setting of Vver-1500, but a fully reasonable decision was soon accepted – to develop a project "Aes-2006"
with a reactor by power 1200 megawatt.A project on every power unit passed for three ecological examinations. Thus two examinations — Rostekhnadzora. The conclusions of Rostekhnadzora testify: a project fully corresponds to the normative documents in area of guard
environment, including – and in part of gradiren. Falls from gradiren will be depreciatingly small as compared to the atmospheric sinking which are characteristic for this district. These falls with gradiren even less that moisture which is brought by wind from Finnish
gulf. On the first public listening on Laes-2, which was passed by two with a half years back, "Rosatomu" there was dan order – to provide a city Pinery a reliable water-supply. On the norms of civil defensive, underground protected vodoistochnik must be included
in a project. In accordance with these norms, in the case of extraordinary situation the certain expense of water must be provided calculating on every habitant. But administration of city put a question wider, namely: to translate all Pinery on a water-supply from underground
source, leaving the water-supply of promzony from the river of Sista. Works are now conducted, to define where it is possible to take water in the district of the country of Karstolovo. A source will be found out and projected.During normal exploitation there is influence of total extrass of radionuklidov
new power units outside a ground will not exceed approximately 0,2% from a natural radiation background, that this size scorned small. It even it is very difficult to fix the devices of radiation control, the permanent monitoring is although conducted
radiation situation.On the ground of Laes-2 the systems of processing are foreseen and liquid, and hard, and gaseous RAO. Investigation of realization in the project of row of new technologies was the considerable diminishing of general volume liquid, hard (except for working
fuels) and gaseous wastes, appearing during work of the station in all project modes. A project is foresee the system of hot-setting of liquid radio-active wastes (ZHRO). It foresees possibility of concentration of deep blue remain, interfusions of him
with cement and packing of cement additive in concrete nevozvratnye protective containers. Nevozvratnye protective containers are intended for temporal storage of RAO on the ground of AES and subsequent portage from the ground of the station to specialized
enterprises for a final burial place.
