The EU TBM systems: Design and development programme

Surface modification and deuterium retention in reduced-activation steels under low-energy deuterium plasma exposure. Part I: undamaged steels

“…The post-mortem analysis was performed using a) SEM equipped with EDX to see surface modification, b) RBS for the analysis of surface elemental composition, c) NRA using nuclear reaction for all different 3 He energy were measured using a surface barrier proton detector placed at an angle of 135°. The D concentration profile was then determined by using SIMNRA to fit its calculated proton spectra to experimental ones.…”

“…Ferritic/martensitic steels are one of the candidate materials for the vessel of the spallation target [1], and reduced-activation ferritic/martensitic (RAFM) steels, such as Eurofer, are first priority materials of structure for fusion nuclear reactors [2,3]. These systems are desired to operate at relatively high temperatures up to 650 С. RAFM steels possess exceptional thermal conductivity and low thermal expansion among other steels while being strongly resistant to void swelling.…”

Wendelstein 7‐X: An Alternative Route to a Fusion Reactor

“…Essential nuclear technology components of a fusion power plant are the breeding blanket for producing tritium from the fusion neutrons and lithium [24,25], the tritium fuel cycle [26], and structural materials which have to withstand the high neutron fluxes. While in ITER the displacement damage is limited to about 1 dpa (displacement per atom), in a fusion reactor up to 30 to 40 dpa/year are expected.…”
