Notes:
The commercial material PM2000 is investigated as a representative for the material classof Oxide Dispersion Strengthened (ODS) steels. ODS steels are envisaged as substance of structuralcomponents in Very High Temperature Reactors (VHTR). The VHTR concept is considered by theGeneration IV International Forum, an initiative researching the next generation of nuclear powerplants. The chosen ODS is mainly used for non-nuclear applications. In order to justify theapplicability of this material within a neutron irradiative environment, the evolution of radiationdamage must be investigated. PM2000 samples are therefore exposed to 4He2+ irradiation at differenttemperatures. The potential structural change is measured as a function of the radiation parameters,using Extended X-Ray Absorption Fine Structure (EXAFS) spectroscopy on the yttrium K-edge andon the iron K-edge. A degradation of the dispersoids or the steel matrix would show the limitation ofthis material candidate
