OKB “GIDROPRESS” took part in activities on life extension of Beloyarskaya NPP Unit 3
OKB “GIDROPRESS” specialists completed their part of work on life extension of Beloyarskaya NPP Unit 3 till 2040.
The specialists of the design-engineering department were responsible for operating life extension of reactor plant BN-60 steam generator modules: evaporators – up to 150 000 hours, steam superheaters – up to 235 000 hours. Justification of possibility of operating life extension was made for critical components of the modules taking into account the results of activities performed at Beloyarskaya NPP during testing and inspection at the Unit, as well as with account of activities performed by OKB “GIDROPRESS” and CRISM “Prometey” during examination of structural material state of the modules, both under operation and with the expired assigned lifetime.
Application of more precise calculational models and methods, as well as steam generator operation experience, enabled to make a conclusion on a possibility of operating life extension of reactor plant BN-60 steam generator modules.
Beloyarskaya NPP Unit 3 with BN-600 reactor is the Unit, first in the world, with the fast neutron reactor. The reactor is developed by JSC “OKBM Africantov”, the steam generator is developed by OKB “GIDROPRESS”. Both organizations are integrated into JSC “Atomenergomash”. The Unit was commissioned in 1980 and still is under safe and reliable operation.
