Article

The design of the modernized moisture separators-reheaters of the TG-1 and TG-2 turbines in the No. 1 unit of the Smolensk NPP is described. The modernization of intermediate moisture separators-reheaters eliminated the nonuniformity of the moisture distribution over the perimeter and height of the steam space behind the separation units. Tests showed that the average moisture content at the egress from the separation units was 0.6%, which is close to the computed value 0.5%.
