Developing Generating Potential
Novovoronezh NPP-2 and Leningrad NPP-2 are the first plants to be built in Russia from scratch for the last thirty years.
BUILDING NEW NPP POWER UNITS
Pursuant to Energy Strategy of Russia until 2030, General Allocation Pattern for Energy Facilities of Russia until 2020, and taking into account the long-term development until 2030, the Concern provides for increase in the share of nuclear power in energy balance of Russia at the same time ensuring necessary safety level, including by way of building new power units of NPPs.
In 2014, construction work on erection of 9 new power units and 1 floating power unit was in progress at the Concern’s nuclear power plants. Six of them were constructed according to the NPP-2006 design which became an evolutionary step in development of the Russian nuclear power industry.
In 2014, construction of new power units was effected under general contractor agreements with engineering companies NIAEP JSC, Atomenergoproekt JSC, and UK Uralenergostroy LLC. General contractors and contractors were selected according to the requirements of the Unified Industry Procurement Standard of Rosatom State Corporation.

COST OF NPP CONSTRUCTION
Due to the current economical situation and tough competition in the NPP design market the Concern faces the task of significant reduction of cost and timelines for construction of new NPP power units. NPP-2006 is currently the basic design for organized serial construction of NPPs of the Russian design both in Russia and abroad.
The construction cost of a standard two-unit NPP according to this design totals 43.4 bln rubles in the basis prices of the year 2000, or 245.2 bln rubles in prices of the 1Q 2014. The power start of the first power unit of an NPP constructed under the NPP-2006 design is accomplished in 6 years and 7 months, and of the second power unit – in 7 years and 7 months after project launch. Maximum expenses on financing of a two-unit NPP are incurred on the fi fth year of construction.
New techniques based on the Rosatom Production System are implemented in order to reduce construction timelines of new power units:
- Preassembly of main circulation pipelines in the pre-installation preparation workshop directly on-site;
- Simultaneous welding at four loops of main circulation pipelines, simultaneous welding of more than two welded seams;
- Supply of turbo-generator К-1000-60/300 in the form of five preassembled blocks;
- Manufacture and assembly of preassembled blocks of the internal containment of the reactor building.
For the first time in Russia, at Leningrad NPP-2 the 328 t reactor vessel of the first power unit was installed using the open top technique using heavy-duty caterpillar crane Liebherr LR 11350. The operation was performed in compliance with all industrial safety requirements.
The quality management system which complies with international standard ISO 9001:2008 “Quality Management Systems. Requirements” was developed and implemented in 2014 by the Concern’s Facility Construction Management Branch in order to regulate operations, make them compliant with international standards, as well as to meet the requirements for participation in international tenders on NPP construction. Certification audit in TÜF Thüringen certification authority was successfully passed, and we received the certificate on conformance of the management system with standard 9001:2008 in the area of design and construction management of facilities intended for peaceful use of nuclear energy as well as production and supply of electric power (reg. No. TIC 15 100 128018).
Unified requirements were introduced for the organization, collection, and analysis of data on production (work, services) quality in the civil nuclear power industry of the Russian Federation, formation and evaluation of successful management solutions, implementation of quality policy of Rosatom State Corporation. Requirements were introduced for organization of the monitoring system of construction and assembly work providing for unified (for all construction sites) collection and analysis of data and information about quality of construction and assembly work.
