Stresses and temperature distribution in the rotor (300MW) during start-up cycle were evaluated using Finite Element Analysis. Geometry of steam turbine rotor has modeled used CATIAV5R20. In this present work, depending upon flow condition over the rotor, structural and transient thermal analysis has been done using ANSYS 14.5 workbench. And variations of temperature over the rotor at different time step have been observed. Stress distribution was validated by comparing it with yield strength of the material and nature of temperature distribution will be validated by comparing it with actual industrial data. As Creep is one of the most important parameter for life assessment of steam turbine rotor thus result obtained which will be utilized for calculating creep. Remaining life assessment of steam turbine rotor can be obtained.
