Assessment of neutron irradiation effects on RAFM steels

Austenitic stainless steel strengthened by the in situ formation of oxide nanoinclusions

“…23,24 Compared with MA-HIP ODS 304 the ODS LM specimens show higher yield strength and much higher ductility. More homogenous dispersion of oxide nanoinclusions and no contamination involved in ODS LM are believed to be the reasons behind this improvement.…”

TEM study and modeling of bubble formation in dual-beam He + /Fe 3+ ion irradiated EUROFER97

“…A meaningful comparison with the observations on boron doped specimens of the neutron irradiation program SPICE is difficult because besides the primarily homogeneous distribution of boron also the formation of BN and M 23 (C,B) 6 precipitates was found [26]. It was further analyzed that the void nucleation is critically influenced by the vicinity of these precipitates [27].…”

FAFNIR: Strategy and risk reduction in accelerator driven neutron sources for fusion materials irradiation data

“…An aggressive target program is therefore proposed that would seek to cooperate with other groups in order to realize a 200kW target and 5mA beam current from the outset of FAFNIR operations. Continuation of that program in parallel to the FAFNIR build, commissioning and early operational activities would enable further rapid upgrade of the facility to achieve the full envisaged capability of 30mA beam current, facilitating irradiations of ~100cm 3 of material in excess of 20dpa by 2030. …”

“…For the upgraded FAFNIR specification the anticipated dose volume is between 40x40x60mm 3 and 50x50x60mm 3 . Within this volume neutron dose and dose rate will vary greatly with depth; irradiation temperature will also vary to some extent with position but it is expected that this variation can be minimized by use of differential external heating and with careful choice of location of test specimens.…”
