| Abstract Scope |
Dynamic SIMS (Secondary Ion Mass Spectrometry) proves extremely useful for a wide range of nuclear science applications. ACTINIS is a SIMS instrument designed to perform high precision elemental and isotopic analyses of highly radioactive samples in a safe environment.
ACTINIS offers depth profiling with excellent detection limits (ppb to ppm) and high depth resolution; elemental & isotopic information ranging from low mass (H) to high mass species (Pu and beyond); as well as unique sub-μm resolution 2D and 3D imaging capabilities.
Studies performed with SIMS on irradiated nuclear fuel focus on three main axes:
1) the nuclear reactions occurring during in-core irradiation which are characterized with isotopic ratio measurements,
2) the physical and chemical behavior of fission products which is evidenced by isotopic mapping,
3) the characterization of fission gases which is carried out through depth profiling measurements.
Different applications covered by ACTINIS for irradiated fuel analysis will be presented. |
