Abstract
Results obtained from upgrading the flow paths of the low-pressure cylinders of OAO Turboatom K-500-6.4/3000 steam turbines installed at the Kursk, Smolensk, and Leningrad nuclear power stations are presented. With the annular area of steam outlet from the last stages increased from 6.3 to 8.19 m2, it became possible to reduce the loss due to outlet velocity by a factor of 1.8 and increase the turbine power output by 16MW, which is equivalent to increasing the power unit efficiency by 3.2%.
