Abstract:
Nickel-based alloys are attractive materials for the nuclear industry and in particular for Molten Salt Reactors (MSR). They are especially considered for neutron reflectors or heat exchangers. These alloys have many advantages, such as high mechanical properties at high temperature, and good corrosion resistance in chloride salt. A new nuance for MSRs is being developed at CEA. This alloy is obtained after consolidation by SPS and/or by HIP treatment of powders obtained by atomization. To resist irradiation, it is necessary to carefully control the nanoprecipitation in the material. This paper aims to show that the use of different characterization techniques, and in particular Small Angle X-rays Scattering (SAXS), makes it possible to specify the thermo-mechanical treatments, suggested to obtain the desired state of precipitation in this new alloy.
