Assessment of Material Properties by Lateral Compression Testing – a Potential Method in Hot Cells for Irradiated Fuel Cladding Evaluation

Original language description

In the nuclear safety, the multiple barriers is one of the most important principle. Act as the first barrier, the integrity of the cladding is a crucial issue in the related research. Concerning the mechanical properties, it has difficulty in obtaining the mechanical property along the hoop direction due to the geometry of fuel cladding. In the present study, the Ring Compression Test has been adopted. The method avoids numerous drawbacks and limitations of traditional testing approach, the simpler experimental setting and easier analysis can therefore be introduced. Candidate material in the study is Titanium stabilized 1.4970 ’15-15Ti’ stainless steel owing to its outstanding radiation resistance ability. 24 % and 46 % cold-worked materials were compressed at room temperature, 300oC, 500oC and 700oC, respectively. Further mathematical analysis and data processing were developed to properly interpret the load-deflection curves. The results show that there were two types of behavior of load-deflection curves, load of the 46 % cold-worked materials tested at 300oC and 500oC declined after reaching certain displacement which were in contrast to all the others test conditions. On the other hand, 46 % cold-worked materials generally demonstrated higher collapse load among all the test temperatures except those were tested at 700oC. These results might relate to the microstructure differences caused by the different amounts of cold-worked in the materials.
