In‐situ Stress Measurements on SUS316L Stainless Steel in High Temperature Water Simulated Boiling Water Reactor
AIP Conference Proceedings(2007)
摘要
An in-situ straining device has been developed, which enables one to apply a load of 240 N to a specimen in hot water at 561 K and a pressure of 8 MPa, simulating the environment in a boiling water reactor (BWR). The device is equipped with sapphire glass windows for a fight path, that is, the device can be used for dynamic measurements of stress induced in the specimen using a synchrotron radiation facility. In-situ stress measurements have been carried out at SPring-8 (BL02B1) on a specimen prepared from SUS316L stainless steel. Inhomogeneity in stress distribution and time-dependent changes in stress were successfully measured.
