Uniaxial tensile test data for P91 ar material at 375 °C (specimen identifier AA-006)

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）框架下，《欧洲可持续核工业倡议（European Sustainable Nuclear Industrial Initiative, ESNII）》2010-2012年实施计划为欧洲第四代原型堆的开工建设设定了极为严苛的时间节点：铅冷快堆（LFR）欧洲技术试验工厂（ETPP）“米里亚”（Myrrha）将于2014年启动建造，钠冷快堆（SFR）原型堆“阿斯特里德”（ASTRID）则将于2017年启动建造。相较于现有核电技术，第四代反应堆拥有更高的运行温度与更严重的材料辐照损伤，这为设计者与科研人员带来了全新的技术挑战。在此背景下，材料试验与规则（MATerials TEsting and Rules, MATTER）项目计划开展针对性研究，以系统探究材料在第四代反应堆运行工况下的行为特性，并确立相关材料在反应堆应用中的正确使用准则。在此框架下，欧盟联合研究中心（Joint Research Centre, JRC）针对P91与316材料开展了多项测试，包括低周疲劳（Low Cycle Fatigue, LCF）、蠕变（Creep）、小冲杆蠕变（Small Punch Creep）以及小冲杆拉伸/断裂测试。上述工作均在材料试验与规则（MATTER）项目框架下完成，资助协议编号：269706。
