Abstract
Thermal ratcheting analysis is an important part of nuclear power station pipe design,which is prescribed based on the Bree diagram in PWR power station.But usually it can't be meet when the pipe subjected large thermal shock and need to a further analysis.The requisition of RCC -Mcode on the cu-mulative deformation damage and feasible engineer criterion is discussed in this paper.The thermal ratch-eting stabilization of a typical pressuriser discharge line is analyzed through the efficiency diagram rule from the material experiment data.It is represented that the affection of thermal ratcheting deformation on pipe operation is small under 500 times cycle thermal shock,the cumulative deformation is in a limit bound,so the pipe is still meet the RCC -Mcode.The efficiency diagram rule based on the material ex-periment data is a simple method which is suitable in the engineer design and could be used in thermal ratcheting analysis of the PWR power station.关键词
