Small punch tensile/fracture test data for P91 material at -50 °C and a displacement rate of .005 mm/s (specimen identifier AD04)

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).

在可持续核能技术平台（Sustainable Nuclear Energy Technology Platform, SNE TP）框架下，《欧洲可持续核工业倡议（European Sustainable Nuclear Industrial Initiative, ESNII）》2010-2012年实施方案为欧洲第四代核电原型堆（Gen IV）的开工建设制定了严苛的时间节点：铅冷快堆（Lead-cooled Fast Reactor, LFR）欧洲技术试验工厂（European Technology Pilot Plant, ETPP）“米尔哈”（Myrrha）的建造将于2014年启动，钠冷快堆（Sodium-cooled Fast Reactor, SFR）原型堆ASTRID则将于2017年开工。相较于现有核电技术，第四代核电反应堆（Gen IV）拥有更高的运行温度，且材料面临更严重的辐照损伤问题，这给设计者与科研人员带来了全新的挑战。在此背景下，材料测试与规范（MATerials TEsting and Rules, MATTER）项目计划开展针对性研究，对第四代反应堆运行工况下的材料行为进行系统深入的探究，并确立相关反应堆应用中材料的正确使用准则。在此框架下，欧盟联合研究中心（Joint Research Centre, JRC）针对P91钢与316不锈钢开展了多项试验，涵盖低周疲劳（Low Cycle Fatigue, LCF）、蠕变、小冲杆蠕变以及小冲杆拉伸/断裂试验。相关研究工作均在MATTER项目框架下完成（资助协议编号：269706）。
