The impact of the hypothetical defects (nicks and scratches) in the steam discharge openings area of disc 2nd stage on medium pressure turbine K-300-240-2 rotor resource under creep is considered. Evaluation of disc damage in the area of openings is investigated with three-dimensional finite element...
