in this paper, the rolling force and reduction ratio have been investigated in multilayer strip rolling. for this purpose, two different set of multilayers have been selected which are al/st/al and cu/al/cu layouts. at first, the validation of the numerical analysis was performed by using an experimental test. after validation of the numerical results, two set of multilayer layouts were simulat...

Graphene, whose absorbance is approximately independent of wavelength, allows broadband light-matter interactions with ultrafast responses. The interband optical absorption of graphene can be saturated readily under strong excitation, thereby enabling scientists to exploit the photonic properties of graphene to realize ultrafast lasers. The evanescent field interaction scheme of the propagating...

Two sodium-bonded, single phase (Uo.8PUo_2)C fueled. Type 316 stainless steel clad fuel elements were irradiated in EBR-II at heating rates of ~30 kW/ft to burnups of 3.7 and 5.0 at ." . No clad failures occurred as a result of the irradiation. Total fission gas release from the fuel was low. Thermal stresses in the fuel resulted in fuel splitting upon initial startup and general fuel fragmenta...

We present a double-clad fiber coupler (DCFC) for use in confocal endomicroscopy to reduce speckle contrast, increase signal collection while preserving optical sectioning. The DCFC is made by incorporating a double-clad tapered fiber (DCTF) to a fused-tapered DCFC for achromatic transmission (from 1265 nm to 1325 nm) of > 95% illumination light trough the single mode (SM) core and collection o...

Quartz fibers are used in high energy physics experiments as the active medium in high radiation area calorimetry. Quartz fibers are also used in the transmission of optical signals. Even though quartz does not damage by moderate amounts of irradiation, the clad of the fibers and the protective coating (buffer) do damage reducing light transmission. Various types of quartz fibers have been irra...

Optical switching based on waveguide optics with a ferroelectric liquid crystal (FLC) is reported. The FLC cell was prepared as a prism coupler on which the liquid-crystal layer was sandwiched between two gold cladding layers. The role of the gold layer was examined, and the optimum thickness of the top gold layer for obtaining high contrast was determined by use of the Fresnel equation. Variou...

The Advanced Fuels Campaign performed a series of irradiation tests minor actinide-bearing mixed oxide fuel (MA-MOX), the so-called AFC-2C&D experiments, to investigate transmutation long-lived transuranic actinide isotopes contained in spent nuclear via fast reactor technology at burnups exceeding 10 % fission initial metallic atoms. This manuscript reports test results derived from one five M...
