OKB “GIDROPRESS” contributed to service live extension of Balakovo NPP Unit 2
Federal Environmental, Industrial and Nuclear Supervision Service of Russia (Rostechnadzor) has granted a license for Balakovo NPP Unit 2 operation till 13 October 2043. The license is obtained with a considerable contribution of OKB “GIDROPRESS” personnel into justification of possibility of service life extension for reactor plant equipment and pipeline of Balakovo NPP Unit 2 for 26 years. The Unit 2 is under operation since 1987. In this power unit a reactor plant with VVER-1000 of V-320 series designed by OKB “GIDROPRESS” is used. 24 power units of this design are constructed and operated in Russia and abroad. All the next following designs of VVER reactor plants used conceptual solutions of V-320 design. The enterprise is the Chief Design of VVER reactor plants and it participates in activities at all stages of life cycles of the designed reactor plants including their service life extension. Service life of the following reactor plants with VVER-440 was extended: Novovoronezh NPP Units 3, 4; Kola NPP units 1, 2, 3, 4; Rovno NPP Units 1, 2 as well as reactor plants with VVER-1000: Novovoronezh NPP Unit 5; Kalinin NPP Unit 1; Balakovo NPP Units 1, 2 and “Kozloduy” NPP Unit 5. OKB “GIDROPRESS” experts have finished works on justification of service life extension of Kalinin NPP Unit 2 (2016) and Balakovo NPP Unit 3 (2017). The work on RP service life extension of “Kozloduy” NPP Unit 5 comes to its final stage.
