Low cycle fatigue - strain control test data for P91 ar material at 600 °C (specimen identifier AA-025)

The 2010-2012 implementation plan of the European Sustainable Nuclear Industrial Initiative (ESNII), in the frame of the Sustainable Nuclear Energy Technology Platform (SNE TP), establishes a very tight time schedule for the start of construction of the European Gen IV prototypes; namely the construction of the LFR ETPP (European Technology Pilot Plant) Myrrha will start in 2014 and that of the SFR Prototype ASTRID will start in 2017. The GEN IV reactors pose new challenges to the designers and scientists in terms of higher operating temperature and higher irradiation damage of materials with respect to the present technologies. In this frame, the MATTER (MATerials TEsting and Rules) Project intends to start well targeted researches to perform careful studies of materials behaviors in GEN IV operational conditions and to find out criteria for the correct use of these materials in relevant reactor applications. In that context, the JRC has carried out different tests (LCF, Creep, Small Punch Creep, Small Punch Tensile/Fracture) tests on P91 and 316. The activities were carried out in the frame of the MATTER project (Grant agreement no: 269706).

欧洲可持续核能产业倡议（ESNII）在可持续核能技术平台（SNE TP）框架下制定的2010-2012年实施计划，为欧洲第四代（Gen IV）原型堆的建造启动设定了极为紧凑的时间表：即液态金属快堆（LFR）欧洲技术试验厂（ETPP）Myrrha将于2014年开工，钠冷快堆（SFR）原型堆ASTRID将于2017年开工。

相较于现有技术，第四代（Gen IV）反应堆在更高运行温度及材料更高辐照损伤方面，对设计人员与科研人员提出了新的挑战。

在此背景下，MATTER（材料测试与规范，MATerials TEsting and Rules）项目旨在开展针对性研究，深入探究材料在第四代（Gen IV）反应堆运行条件下的行为，并为这些材料在相关反应堆应用中的正确使用确立标准。

在此背景下，联合研究中心（JRC）针对P91与316材料开展了多种测试，包括低周疲劳（LCF）测试、蠕变测试、小冲杆蠕变测试及小冲杆拉伸/断裂测试。这些活动是在MATTER项目（资助协议编号：269706）框架下实施的。
