Analysis of Wear Reasons and Gap Repair of the Last Stage Blade Shrouds in Russian Made Nuclear Power Plants
In this paper,both experimental and FE methods are used to analyze the factors which lead to the wear and tear of the last stage blade shrouds of a nuclear power turbine.Based on the safety and economic consideration of shrouds under different clearances,the range of shrouds clearance during safe operation is determined.Further,the repairation method and implementation process of the shrouds clearance are given,which will provide an important theoretical basis for the last stage blade maintenance.
