Post irradiation examination of RAF/M steels after fast reactor irradiation up to 71 dpa and < 340°C (ARBOR 2) : RAFM steels: metallurgical and mechanical characterisation

The objective of the ARBOR 2 irradiation programme was to study the effects of low-temperature (330-340 °C) high dose (up to 70 dpa) neutron irradiation on the mechanical properties of the European reference structural material for the Demonstration Reactor (DEMO), EUROFER97, its Oxide Dispersion Strengthened (ODS) variants, selected technological specimens and other international RAFM steels. The impact, tensile and LCF properties have been studied by implying small specimen testing technology.
