| Tender Title | Residual Life Assessment study (RLA) of Turbine and Generator Rotor shafts of Unit No.1 and 2 Machines at Neriamangalam Power Station |
|---|---|
| Tender Description | rla of turbine and generator rotor shafts of unit no.1 & 2 machines at neriamangalam ph ndt (for identification of surface and sub-surface internal defects) dpt and magnetic particle inspection of the turbine generator shafts in the accessible regions. advanced ultrasonic b-scan imaging to identify pre existing cracks in the turbine generator shaft.fem modeling and damage tolerance studies: 3d geometrical modelling of both generator and turbine shafts. stress analysis of the generator and turbine shaft without any defects. growth life estimation.introduction of geometries in different locations on the modelled shaft as identified by ut-b scan and re-meshing.estimation of remaining life based on the grouth rate already observed and re-defining of the grouth rate constants on an interactive basis involving multiple growth steps to match the observed growth rate. |
