This article illustrates AREVA T&Dpsilas position in terms of their productspsila end of life management. In order to manage the equipments that have reached the end of useful life, this study describes complete dismantling operation diagram, recycling routes and waste management.
Phase-field simulations were used to explore the effect of the characteristics of the Landau-Devonshire free energy and values of electrostatic and elastic interactions on the formation of different types of domain structures in ferroelectric thin films. Simulations were performed at different constant-applied electri…
Chloride salt wastes, which are supposed to be generated from a pyrochemical processing of spent nuclear fuels, are one of the wastes that are problematic to treat because of their high solubility in water and the relatively high volatility of some of their nuclides during a high-temperature thermal treatment. In this…
In order to obtain oriented nanostructured materials for nanoelectronic/microelectronic applications, a simple sol-gel method to form ZnO nano-structures under different heat treatment conditions was investigated. The results indicated that ZnO nanobelts could be obtained by the presence of small amount of triethanola…
Abstract One of the main obstacles to performing electron crystallography analysis in a TEM is that the acquired electron diffraction data often exhibits some form of distortion introduced by the lens system. Recognizing this problem, Capitani et al. has proposed a method to detect such distortion, which is primarily…
The inhibition effect of N-benzyl-N –pheny1 thiourea (BPTU) on the corrosion of mild steel in 0.01 and 0.05 N HC1 medium has been investigated by potentostatic polarization technique. Results obtained reveal that BPTU is an efficient anodic inhibitor with greater than 94% of efficiency in the range of temperature stud…
We have developed holographic gratings that enable the asymmetric polarization conversion between ±1-order diffraction beams. The holographic gratings are formed by polarization holography in a poly[(methyl methacrylate)- co -(disperse yellow 7 methacrylate)] film and show both anisotropic phase and surface modulation…
Silicon nanocrystals prepared in phosphorus-doped (at a concentration of 3.3 × 10 20 cm −3 ) amorphous silicon films under pulsed irradiation with an excimer laser are studied using Raman spectroscopy and electron microscopy. The experimental data can be interpreted in terms of the Fano interference as a manifestation…
The main objectives of a TRISO treatment are to effectively breach and separate the carbon and SiC layers composing the TRISO particles. The reported technologies used to treat a spent TRISO fuel are almost identical, involving a final wet chemical process under which crushed TRISO fuel is processed to separate the co…
In order to develop reliable on-site partial discharge (PD) pattern recognition algorithm, the fuzzy set-based fuzzy neural network (FNN) was investigated and designed. Using PD data measured from laboratory defect models, this algorithm was designed and tested. Considering the on-site situation where it is not easy t…
IASCC behavior in cold-worked SUS316 stainless steels irradiated to 35 dpa was examined using slow strain rate tensile testing at a strain rate of 6.7 × 10−8/s in 320°C simulated PWR primary water while varying the dissolved hydrogen (DH) concentration from 0 to 2.8 ppm. The results were compared with those previously…
The values of the product of the inelastic mean free path and the differential cross section for inelastic scattering of electrons have been determined from the reflection electron-energy-loss spectra of thin films of the Fe x Si1 − x system (0 ≤ x ≤ 1). A new approach to the quantitative analysis of components in suc…
Granulated sorbents that can recover zinc salts from aqueous solutions were produced by poly-condensation of organochlorine wastes from manufacture of epichlorohydrin with sodium polysulfide on the surface of ash-and-slag particles formed at thermal power plants in the system constituted by aqueous hydrazine and an al…
One of the most remarkable properties of smectics is the wide variety of possible equilibrium structures. In this paper, based on the Landau theory of the phase transitions, the transitions between ferroelectric and antiferroelectric phases and the structure formed by smectic layers with different azimuthal and polar…
Controlled multipulse loading in classical split Hopkinson pressure bar (SHPB) testing is highly desirable for investigating loading history dependent phenomena but rarely explored. Here, we present a novel technique to achieve controlled multipulse loading in SHPB testing with a stuffed striker. This stuffed striker…
The low-field dielectric responses of pure and 0.15wt.% MnO-added (1−x)Pb(Fe2∕3W1∕3)O3–xPbTiO3 [(1−x)PFW–xPT] were investigated with the empirical model, the Curie–Weiss law and the spin-glass model. According to the experimental data and the fitting results, we conclude that (1) the lattice structure is changed and t…
The Global Nuclear Energy Partnership program (GNEP) is designed to demonstrate a proliferation-resistant and sustainable integrated nuclear fuel cycle that can be commercialized and used internationally. Alternative stabilization concepts for byproducts and waste streams generated by fuel recycling processes were eva…
Anodisation of AZ31 Mg alloy (3 mass%Al, 1 mass%Zn) was performed in 1M NaOH solution, with and without adding 35 mM of calcium hydroxide at various temperatures. The anodising process was carried out at constant potential 3 V; the change in current density during the first period of anodising revealed the mechanisms…
Using the first-principles calculations a comparative analysis of electronic structure and optical properties of crystalline Si with cubic Mg 2 NiH 4 and monoclinic Mg 2 NiH 4 has been performed. It is found that the band structure of cubic Mg 2 NiH 3 is similar to that of crystalline Si ( c -Si), whereas the band gap…
In order to adequately simulate the behavior of a Hall–Héroult electrolysis cell, a finite element model must take into account the properties of each material forming the cell structure and those contained in it. However, there is some lack of full knowledge of the mechanical behavior of these materials, e.g., the lo…
