The status of component parts of external and internal penstocks is analyzed on the basis of data derived from field observations during the construction and service periods of the Ust’-Ilimsk and Bureya HPP as examples. The stress state of the internal penstock is more favorable as compared with the that of the external penstock; cracks with an opening exceeding the standard permissible value are developing in the reinforced-concrete structures.
