Nuclear power plants play an important role in power systems of many countries. Ability to reasonable increase installed capacity of nuclear power units allow to reduce the cost for building of new power plants. When increasing NPP capacity to 104% there is a need to estimate the residual life of plant’s typical elements and continue their operation. The mathematical model of estimation of service life indicators of steam turbine K-1000-60/3000 is developed. The effect of increasing the capacity of a nuclear reactor on the heat transfer coefficients of a steam in the nozzle segments of high-pressure cylinder was established by using CFD modeling. The thermal and stress-strain state of the high-pressure rotor for the most typical operating modes are calculated. Using the correlation dependences of low-cycle fatigue, the rate of accumulation of cyclic damage of the base metal is established. The resistance of the metal to the exhaustion of long-term strength is also determined. On the example of the high pressure rotor of the 3^rd power unit of Rivne NPP the service life indicators are calculated. The validity of increasing the installed capacity of the power unit was also confirmed.
