Abstract : An introduction to the vibration isolating design and check calculation of the spring supported foundation of
Tianwan Nuclear Power Plant’s turbine generator set is being presented , together with a substantiation of relevant design
parameters , such as the vibration isolation efficiency. Simultaneously , the design of the condenser’s supporting springs is
being described , panied by an analysis of the influence , on the turbine cylinders , of the condenser’s weight
distribution , both during installation and operation. How vibration isolation technique has been made use of in the turbine
generator rotor system’s alignment is also being elucidated.
