Luminescence properties of pure silica core optical fibers (OFs) with a high-OH group content are studied in the visible region at different doses and dose rates of 60Co γ-radiation. It is shown that the γ-induced light emission (GLE) spectra consist of Cherenkov emission along the luminescence bands. Different increa…
The Korea Atomic Energy Research Institute (KAERI) has been developing a dual-cooled annular fuel for the power uprate of 20% in an optimized pressurized water reactor (PWR) in Korea, OPR1000. The dual-cooled annular fuel is configured to allow the coolant flow through the inner channel as well as the outer channel. S…

Using numerical code RFPA2D (dynamic version), spallation processes of rock-like medium induced by reflection of stress wave with different rise time and decay time are simulated, and based on description and discussion on the failure area in the document [1], the influence of the rise time and decay time of stress wa…
Several constant spring supports attached to the main steam lines (MSLs) at Palo Verde Nuclear Generating Station (PVNGS) failed over a period of several years. The continued failures presented a need to instrument the MSL piping and supports, such that data could be collected in support of a cause determination and p…
A number of organic fluorescent molecules self-assembling into nanoparticles can significantly promote their fluorescent effects. In this paper, a novel fluorescein isothiocyanate labeling aminated agarose (FITC-AA) is prepared and tested as an effective fluorescent labeling agent. FITC-AA self-assembled into nanopart…
Recent experimental observations of the central peak in SrTiO 3 near the temperature Tc ≈100K of displacement type structural phase transition are explained. The peak intensity temperature dependence observed in the experiments is shown to be attributable to dislocation induced contribution.
In this paper we study the interface strength obtained through two‐component (2C) injection molding of LDPE‐HDPE polymers. First, numerical simulation of the over‐molding process is carried out using Moldflow technology. Second, butt‐joint specimens were produced by over‐molding under different process condition, and…
Molecular dynamics simulations using embedded atom method inter-atomic potential were used to study crack propagation under cyclic loading in a Ni single crystal and a Ni-Al bi-metallic system. The crack in Ni-Al initiates and propagates from Ni towards the Ni-Al interface. The cyclic loading was applied in a strain c…
The Sellafield Magnox Swarf Storage Silo (MSSS) was constructed to provide an underwater storage facility for irradiated magnox cladding metal swarf, as well as miscellaneous beta-gamma waste from several sources. Liquid effluent arisings from hazard reduction activities at this facility represent the toughest effluen…
The transport electron scattering due to micro‐twin (MT) defects in InSb quantum wells (QWs) has been investigated at room temperature (RT). A linear‐regression‐based scattering analysis showed that Matthiessen's rule is applicable to the RT electron mobility in 20‐nm‐thick InSb QWs that contain MTs (whose density is…
In order to develop a principle of the materials design for the high CO2 generation efficiency during the C2H5OH electrooxidation, the reaction pathways during the electrooxidation of C2H5OH and CH3CHO which is a by-product during the electrooxidation of C2H5OH have been quantitatively analyzed. As a result, a direct…
This paper focuses on study of a space high reliability microprocessor which is designed for space platforms, such as on-board computer systems. Space radiation environment is a special factor that should be considered when we design space high reliability processor. The architecture of Leon 3 microprocessor is invest…
A new guide has been developed for the field evaluation of concrete pavements affected by materials-related distress (MRD). The guide assists technical personnel in identifying whether a pavement is affected by MRD and, if so, to what degree. On the basis of the observed manifestation of MRD, an MRD rating is calculat…
Kazakhstan’s BN-350 fast reactor was shut down in 1999 and is in the process of being decommissioned in preparation for Safestore. A key achievement during 2010 was the removal of the known inventory of spent nuclear fuel (SNF) from the reactor to off-site secure storage. As a complementary activity, surveys of areas…
In the present work deep level transient spectroscopy (DLTS) and high-resolution Laplace DLTS were employed to study the electrical properties of defects in as-grown and H-plasma treated CdTe thin films grown by the molecular beam epitaxy technique. We demonstrate that two dominant deep states in as-grown CdTe have th…
A wide flame atmospheric pressure plasma jet has been developed by using a slit nozzle for large area treatment of surfaces. The width of the plasma treated surfaces has been broadened to more than 5 times that obtained by conventional nozzle. The proper function of the slit nozzle towards surface treatment is confirm…
One of the factors that affect the performance of proton exchange membrane fuel cells (PEMFC) is the loss of electrochemically active surface area of the Platinum (Pt) based electrocatalyst due to platinum dissolution and sintering. The intent of the current research is to understand the effect of mechanical vibration…
Les corrosions par piqûre et par crevasse font partie des formes de corrosion les plus dommageables pour les aciers inoxydables lorsqu’ils sont utilisés dans des solutions aqueuses contenant des ions chlorures. Le caractère localisé de ces formes de corrosion les rend difficiles à détecter pour la piqûre, difficile à…
