This paper reviewed the current status on research and development of advanced nuclear materials and the problems to be solved for getting new materials and new fabrication processes into nuclear market. The development of advanced materials solutions including advanced materials and processes is moving much faster than the actual ability of the nuclear industry to introduce them into design codes. Indeed, getting new materials and new fabrication processes into nuclear market requires many years (approximately 10-20 years) of research, development, qualification and licensing. If the nuclear industry wants to get these innovations into market for the building of advanced reactors, issues of qualification and licensing have to be addressed. New frameworks of development and licensing have to be imagined and international collaboration has to be reinforced to work on the establishment of common data platforms for validation and qualification for these new materials and processes.

The phonon dispersion curves of the unconventional superconductor PuCoGa$$_5$$ were studied by inelastic X-ray scattering at room temperature. The experimental data agree well with ab initio lattice dynamics calculations. An accurate theoretical description of the phonon spectrum is obtained only when a local Coulomb repulsion $$U{approx}$$3 eV among 5f electrons is taken into account. This implies partial localization of the 5f electrons in this compound. A comparison made with the phonon spectrum of UCoGa$$_5$$ suggests that the latter compound is better described with a fully itinerant f electrons model.

The phonon dispersion curves of the superconductor PuCoGa$$_{5}$$ were studied by inelastic X-ray scattering at room temperature. The experimental data agree well with ${it ab initio}$ lattice dynamics calculations. An accurate description of the phonon spectrum is obtained only when a local Coulomb repulsion U$${simeq}$$ 3 eV among 5$$f$$ electrons is taken into account.
