Different approaches to problems associated with evaluation of the strength and service life of hydraulic turbines with service lives exceeding the period assigned by the manufacturer are compared. Significant differences in approaches to strength evaluation in the design, construction, and modernization stages, and during an extension in service life are cited. Acomplex approach permitting establishment of a valid prediction of the behavior of a hydraulic turbine during an extended period of operation is proposed for assessment of remaining service life. © 2014 Springer Science + Business Media New York.

The effectiveness of replacement of obsolete and physically worn hydraulic-turbine equipment at the Irkutsk HPP is examined. Parameters of a new type of Kaplan impeller are substantiated with consideration of regime conditions at the HPP and structural characteristics of the hydraulic unit. © 2015 Springer Science+Business Media New York

The opinion that fatigue failure of the cover attachment to the turbine in the No. 2 generating set at the Sayano-Shushenskaya HPP occurred as a result of its operation with a temporary impeller, which had experienced acute hydraulic imbalance duringthe start-up period, is widely adopted among water-power engineers. The unfounded basis of this explanation for events at the Sayano-Shushenskaya HPP is indicated in this paper. © 2014 Springer Science + Business Media New York.

Factors determining fatigue failure of the weldment between the stator column and upper stator ring after 50 years of service of the generating set are investigated. Residual stresses in the zone of the weldment are measured, the natural vibration frequencies of the columns determined, and the static and dynamic stresses in the columns measured in various operating regimes. It is concluded that the basic cause of weldment failure was an original production defect. © 2014, Springer Science+Business Media New York.

Thermal high-pressure deaerators with a capacity of 1000 tons/h have been developed and installed at the Kostroma State Regional Power Plant and the Wang-Bi Thermal Power Plant in Vietnam. The deaerators can be constructed with a vertical or horizontal deaeration column installed on a deaerator tank with the required volume. Based on this positive operating experience, it is appropriate to develop proposals for the composition and design of a commercial feed-water deaerator with a capacity of 1000 tons/h for use in 200 – 300-MW power generating units. © 2016, Springer Science+Business Media New York.
