| Abstract: | The turbine generator has a solid-base and spring-base normally.The spring-base has many advantages： it can reduce the system frequency to avoid resonance.Aiming at connections between steam turbine and condenser,the spring base of nuclear conventional island and combination of condenser spring-support connections have been analyzed,and load allocation of the equipment has been considered.Specific instructions for the installation of condenser spring-base and adjustment of the spring before and after the water filling test have been provided. |
