HIP Cylinder Load Distribution Technology Application in 1 000 MW Nuclear Power Half-speed Steam Turbine |
| |
| Abstract: | Ningde Nuclear Power Plant（CPR1000 PWR） Unit 1 nuclear turbine is the first domestically-made 1 000 MW half-speed steam turbine in China,and HIP cylinder load distribution is the key process in proper installation.The paper describes its structure,major difference with conventional thermal power and load distribution technical control points in site.With the technology in site installation,subsidiary stress in HIP cylinder installation was eliminated,and the steam turbine＇s installation quality was assured,and it offers reference for other similar cylinder load distribution. |
