NPP-2006 project is a project of new III+ generation NPP with improved performance characteristics. The purpose is to achieve up-to-date safety and reliability characteristics at the same time as optimized capital investments for plant construction. The design provides for use of VVER reactor with electric power output of at least 1150 MW (and an option of uprating to 1200 MW). It is planned to achieve the following characteristics: availability factor – 92%, period between refueling – up to 24 months.
From the point of view of safety, the design implies observation of all requirements of Russian scientific and technical documentation, as well as maximum consideration for IAEA recommendations. The major distinguishing feature of the project is the use of additional passive safety systems in combination with traditional active systems. The design provides for protection against earthquake, tsunami, hurricane, aircraft impact. The examples of improvements are: double containment of the reactor hall; molten core catcher located under the reactor vessel; passive residual heat removal system. The design is developed on the basis of water-moderated water-cooled power reactor (VVER) plants, which have proved their reliability through one thousand reactor years of failure-free operation.
Several workgroups participate in the design preparation, including representatives of OKB Gidropress, OKBM, Kurchatov Institute, Rosenergoatom Concern, Atomstroyexport, the three ‘Atomenergoproekt’ ingeneering companies, VNIIAES, a number of other organizations and enterprises. This project is expected to implement the best solutions and experience accumulated during the development of NPP U-87, NPP-91, NPP-92, U-87/92 designs, as well as Russian-built Kundakulam NPP (India) and Tianwan NPP (China).
Two NPP projects are currently being developed under the approved requirements specification: Novovoronezh NPP-2 (general designer – JSC Atomenergoproject, Moscow) and Leningrad NPP-2 (general designer – JSC Atomenergoproject, Saint Petersburg). Competitive approach will in the future allow to accept the best decision at the time of development of commercial NPP construction in accordance with the federal target program of nuclear power engineering development.
