“…Because Am is easily lost during high-temperature processing (e.g., [12,13]), it is particularly important to correctly identify Am-bearing phases. Understanding rare-earth phases is also important because these elements can migrate to the surface of fuel pins during irradiation and interact with cladding to cause fuel failures [14][15][16].…”

a b s t r a c t Structural, microstructural, and microchemical data were collected from rare-earth inclusions in an as-cast U-Pu-Zr alloy with 3 at.% Am, 2% Np, and 9% rare-earth elements (La, Ce, Pr, and Nd). Two RE phases with different concentrations of Am were identified.The composition of high-Am RE inclusions is 2-5 at.% La, 15-20% Ce, 5-10% Pr, 25-45% Nd, 1% Np, 5-10% Pu, and 10-20% Am. Some areas also have O, although this does not appear to be an essential part of the high-Am RE phase. The inclusions have a face-centered cubic structure with a lattice parameter a 0.54 nm.The composition of the only low-Am RE inclusion studied in detail is 35-40 at.% O, 40-45% Nd, 1-2% Zr, 4-5% La, 9-10% Ce, and 6-7% Pr. This inclusion is an oxide with a crystal structure similar to the roomtemperature structure of Nd 2 O 3 . Microstructural features suggest that oxidation occurred during casting, and that early crystallization of high-temperature oxides led to formation of two distinct RE phases.

“…They have the advantage of simple fabrication, high burn-up, good thermal response, and relatively simple recycling using melt refining or electro-refining processes. [1] Uranium-plutonium-zirconium (U-Pu-Zr) alloys comprise the leading metallic fuel candidates for fast reactor and transmutation fuel applications. However, metallic fuels have several disadvantages as compared to alternative fast reactor fuels, such as an affinity for fuel-cladding chemical interaction (FCCI).…”

This work investigates fuel-cladding chemical interaction (FCCI) between U-25Pu-14Zr (in wt pct) fuel and pure Fe at elevated temperatures, understanding of which is critical for evaluation of the fuel performance. Phases and microstructure formed in the quaternary uranium-plutonium-zirconium-iron (U-Pu-Zr-Fe) system were characterized using the transmission electron microscopy technique. Phases formed within the FCCI layer were identified using selective area electron diffraction (SAED) analysis as Fe 2 U (Fd-m), Fe 2 Zr (Fd-3m), a-U (Cmcm), Fe 2 Pu (Fd-3m), b-Pu (C12/m1), and b-Zr (Im-3m).

“…In recent years innovative fast neutron reactor designs have been proposed for burning fissile isotopes that can be constituents of the existing nuclear waste, while at the same time nuclear energy can be produced [1,2]. Towards this direction, the upgrading of the existing nuclear data libraries with accurate experimental information in the fast neutron energy region is of primary importance.…”

The (n,2n) reaction for the lightest stable erbium isotope Er162 from reaction threshold up to 19 MeV

et al. 2018

The 162 Er(n, 2n) 161 Er reaction cross section (E th = 9.26 MeV) was measured at six incident neutron beam energies by means of the activation technique. Two energy regions were covered in the present work: the nearthreshold energies between 10.7 and 11.3 MeV, as well as the higher energies from 17.1 up to 19.0 MeV. In this way, the energy range from the reaction threshold up to 19 MeV was experimentally mapped, considering also the existing experimental information around 14 MeV. The quasi-monoenergetic neutron beam at near-threshold energies was produced via the 2 H(d, n) 3 He reaction, while the higher neutron beam energies were achieved by using the 3 H(d, n) 4 He reaction. The primary deuteron beam was delivered in both cases by the 5.5 MV Tandem Van de Graaff accelerator of NSCR "Demokritos." Statistical model calculations were performed and compared with all the available experimental data.
