The application of nuclear technology is currently spreading over the world. Given the possibility of devastative risk, the lifetime performance and especially the safety of nuclear installation are raising big concern to human society. Therefore, the assessment of mechanical properties and development of relevant measurement methods in nuclear installation are becoming extraordinarily important and are being intensively investigated. This field of research usually covers a wide range of subtopics, with the main focus on both fundamental sciences and advanced technologies for boosting the study of mechanical properties of nuclear installation and its related measurement. For example, fracture mechanics are useful to predict the temporal and long-term reliability of nuclear reactors under aggressive loads. Advanced functional materials (such as alloy and thermal barriers coatings) with superior thermal and mechanical resistance to harsh environment can be applied in nuclear installation. Also, it is of significant interest to analyze and characterize these materials by using state-of-the-art measurement methods, including scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, high resolution transmission electron microscope, and various optical measurement methods.

We are pleased to invite authors to submit original articles as well as review papers on research and development of the mechanical properties in the nuclear installation and its measurement method. The special issue is soliciting all articles that will highlight recent major breakthroughs, progress, and challenges in properties and measuring methods of nuclear installation.

Potential topics include, but are not limited to:

• Fracture mechanics, fatigue, creep-resistance, material strengths, ductility, thermal aging effect, irradiation effect, wear resistance, erosion/corrosion, multiscale simulation, microstructure observation, and corresponding measurement methods
