The present paper proposes new creep life prediction methods that can be used in situ as an in-service inspection tool for the condition based monitoring of high-temperature structure components of 316FR stainless steel. The methods are based on two types of the modified theta methods and the combination of the modified and omega methods are applied to creep deformation data measured in the creep tests made at different applied stress levels at 823-923 K in air. Creep lives were predicted by the propos...

In Situ Creep Life Prediction Methods for Austenitic Stainless Steel 316FR

The Tokai Reprocessing Plant (TRP) is developing the technology to recover uranium and plutonium from spent nuclear fuel. There is an analytical laboratory which was built in 1977, as one of the most important facilities for process and material control analyses at the TRP. Samples taken from each process are a nalyzed by various analytical methods using hot cells, glove boxes and hume-hoods. A large number of maintenance work have been so far carried out and diffe rent types of experience have been accum...
