AbstractAbstract
[en] Recently, Lead-Bismuth Eutectic (LBE) or Lead has newly attracted considerable attraction as a coolant to obtain a greater inherent safety. Above all, LBE is preferred as the coolant and target material for an accelerator-driven system (ADS) due to its high production rate of neutrons, effective heat removal, and a very small amount of radiation damage properties. But, the LBE or lead as a coolant has a challenging problem in that the LBE or Lead is more corrosive to the construction materials and fuel cladding material than sodium because the composing materials of steel, Ni, Cr, and Fe, dissolved in liquid lead or LBE. After all, LBE or Lead corrosion has been considered as an important design limit factor of ADS and LMFBR. Lead-alloy corrosion test loop named KPAL (KAERI Pb-Alloy Loop) has been designed and fabricated at the Korea Atomic Energy Research Institute (KAERI) and the initial operation was performed recently. The test fluids of KPAL-I and KPAL-II were LBE and lead, respectively. The KPAL-I was designed to study the long-term corrosive effects of liquid lead-bismuth on structural and fuel cladding materials at temperatures up to 550 .deg. C. The first run of KPAL-I took place on September 12th, 2006 and dozens of hours of shakedown testing have been performed with an isothermal condition at about 450 .deg. C. The KPAL-I is scheduled to be ready for a 1000-hour material test at 450 .deg. C. The main objective of the present paper is an introduction of KPAL-I and the results of the shakedown testing

AbstractAbstract
[en] Tunneling measurements of quench-condensed In-Mn and Pb-Mn alloy films were made. The results were compared with Shiba's theory of superconductors containing magnetic impurities. The localized excited impurity states predicted by Shiba's theory were observed in both alloys. In addition to s-wave scattering, it was necessary to include p- and d-wave scattering of the conduction electrons in the theory in order to explain the experimental data. Partial agreement between the theory and the experimental data was obtained using phase shifts from band calculations by A.B. Kunz. The results on In-Mn also agree with thermal conductivity data

AbstractAbstract
[en] This paper describes the electrical design and evaluation of the Josephson cross-sectional model (CSM) experiment. The experiment served as a test vehicle to verify the operation at liquid-helium temperatures of Josephson circuits integrated in a package environment suitable for high-performance digital applications. The CSM consisted of four circuit chips assembled on two cards in a three-dimensional card-on-board package. The chips (package) were fabricated in a 2.5-μm (5-μm) minimum linewidth Pb-alloy technology. A hierarchy of solder and pluggable connectors was used to attach the parts together and to provide electrical interconnections between parts. A data path which simulated a jump control sequence and a cache access in each machine cycle was successfully operated with cycle times down to 3.7 ns. The CSM incorporated the key components of the logic, power, and package of a prototype Josephson signal processor and demonstrated the feasibility of making such a processor with a sub-4-ns cycle time

AbstractAbstract
[en] A hard sphere model is used to interpret atomic transport processes in indium-lead alloys. The experimental data lead to hard core diameters of 3.04A for indium and 3.40A for lead. The distances between the origin and the first minimum of the pair potential curves are 3.1A and 3.3 A for indium and lead respectively. Thus, within the accuracy of the data, the results obtained from theory and experiment are in good agreement

Les phenomenes de transport atomique sont interpretes dans le systeme indium-plomb a l'aide d'un modele de spheres dures. A partir des donnees experimentales, on obtient des diametres de coeur dur de 3,04A pour l'indium et 3,40A pour le plomb. Les distances entre l'origine et le premier minimum des courbes representatives des potentiels de paires sont respectivement de 3,1A et 3,3A pour l'indium et le plomb. Compte tenu de la precision de nos resultats, les diametres de coeur dur obtenus sont compatibles avec ces valeursOriginal Title

AbstractAbstract
[en] In the construction of the ITER, a Test Blanket Module (TBM) will be installed for the verification of the tritium breeding using lithium by neutrons from the plasma. There have been some forms of lithium like solid or liquid one to be considered as a breeding material. In KAERI, liquid lithium material has been considered for the breeding material. Pb-15.7Li, where Li is 15.7 at %, hereafter called PbLi, has been procured and experimented for its basic characteristics. The result will be applied to the operation of a test loop called ELLI (Experimental Liquid Lithium, which is now constructed at KAERI as shown in Figure 1) where effect of magneto-hydro dynamics and materials compatibility will be assessed

AbstractAbstract
[en] Hydrogen gas diffusion anodes (HGDA) have been considered previously as alternatives to oxygen-evolving lead alloy anodes in metal electrowinning. Despite their higher capital costs, the substantial decrease in electrowinning production costs potentially offered by HGDAs is causing renewed interest in their industrial use. This paper reviews the more recent applications of hydrogen gas diffusion anodes in industrial electrowinning. Using data from the literature, a simplified economical assessment is presented for a zinc electrowinning tank house implementing hydrogen gas diffusion anodes; optimum operating current densities of about 3 kA m-2 are predicted.

AbstractAbstract
[en] Purpose : The Conformal Radiation Therapy has been widely used under favour of development of computer technologies. The delivery of a large number of static radiation fields are being necessary for the conformal irradiation. In this paper, we investigate dosimetric characteristics on penumbra regions of a multileaf collimator(MLC), and compare to those of lead alloy block for the optimal use of the system in 3-D conformal radiotherapy. Materials and Methods : The measurement of penumbra by MLC or lead alloy block was performed with 6 or 10 MV X-rays. The film was positioned at a dmax depth and 10 cm depth, and its optical density was determined using a scanning video densitometer. The effective penumbra, the distance from 80% to 20% isodose lines and 90 to 10 were analyzed as a function of the angle between the direction of leaf motion and the edge defined by leaves. Results : Increasing MLC angle (0-75 .deg.) was observed with increasing the penumbra widths and the scalloping effect. There was no definite differences of penumbra width from 80% to 20% isodose lines, while being the small increase of penumbra width of lead alloy block are agree reasonably with those of MLC within 4.8mm. Conclusion : The comparative qualitative study of the penumbra between MLC and lead alloy block demonstrate the clinical acceptability and suitability of the multileaf collimator for 3-D conformal radiotherapy
