Application and testing of a triple bubbler sensor in molten salts

Williams A.N.,Shigrekar A.,Galbreth G.G.,Sanders J. 한국원자력학회 2020 Nuclear Engineering and Technology Vol.52 No.7

A triple bubbler sensor was tested in LiCleKCl molten salt from 450 to 525 C in a transparent furnace to validate thermal-expansion corrections and provide additional molten salt data sets for calibration and validation of the sensor. In addition to these tests, a model was identified and further developed to accurately determine the density, surface tension, and depth from the measured bubble pressures. A unique feature of the model is that calibration constants can be estimated using independent depth measurements, which allow calibration and validation of the sensor in an electrorefiner where the salt density and surface tension are largely unknown. This model and approach were tested using the current and previous triple bubbler data sets, and results indicate that accuracies are as high as 0.03%, 4.6%, and 0.15% for density, surface tension, and depth, respectively

Computational Analysis of the Effect of Different Electrode Design Parameters on the Electrochemical Performance of Lithium Ion Cells

( Williams Agyei Appiah ),박주남,변승우,유명현,이용민 한국공업화학회 2018 한국공업화학회 연구논문 초록집 Vol.2018 No.0

To meet the various application requirements of LIBs, the energy and power density of LIBs needs to be optimized for a given electrode material by controlling its porosity and thickness. Changes in electrode thickness and porosity affect the electrochemical performance of LIBs. Hence we employ a mathematical model to study and optimize the electrochemical performance of graphite/LiNi_0.6Co_0.2Mn_0.2O₂ cells with different cathode thicknesses and porosities. A non-linear least square method is used to provide a better understanding of the different porosities and thicknesses on Li-ion transport in both liquid and solid phases. Ragone plots are generated for the various cell designs where the specific energy and average specific power are evaluated. The cells are optimized for discharge times ranging from 10 h to 2 min in order to map the maximum performance of this chemistry under wide operating range.

Quantification of Capacity Fade Mechanisms in Spinel LiMn₂O₄/Graphite Lithium Ion Cell

( Williams Agyei Appiah ),박주남,변승우,유명현,이용민 한국공업화학회 2018 한국공업화학회 연구논문 초록집 Vol.2018 No.0

To quantify the capacity fade mechanism in lithium ion batteries composed of a spinel-based cathode and an artificial graphite, a comprehensive mathematical model describing the cycling performance of LiMn2O4/graphite lithium ion cell is developed in this work. The developed model is incorporated into the Newman’s Porous Composite Electrode framework (PCE) and implemented in the battery module of COMSOL Multiphysics. The proposed model is used to investigate the effects of variations in the ambient temperature and of voltage range of cycling on the capacity fade. The effect of changes in the volume fraction of cathode active material, resistance in the cell and state of charge are also studied.

A MICROSTRUCTURAL MODEL OF THE THERMAL CONDUCTIVITY OF DISPERSION TYPE FUELS WITH A FUEL MATRIX INTERACTION LAYER

Williams, A.F.,Leitch, B.W.,Wang, N. Korean Nuclear Society 2013 Nuclear Engineering and Technology Vol.45 No.7

This paper describes a finite element model of the microstructure of dispersion type nuclear fuels, which can be used to determine the effective thermal conductivity of the fuels during irradiation. The model simulates a representative region of the fuel as a prism shaped unit cell made of brick elements. The elements within the unit cell are assigned material properties of either the fuel or the matrix depending on position, in such a way as to represent randomly distributed fuel particles with a size distribution similar to that of the as manufactured fuel. By applying an appropriate heat flux across the unit cell it is possible to determine the effective thermal conductivity of the unit cell as a function of the volume fraction of the fuel particles. The presence of a fuel/matrix interaction layer is simulated by the addition of a third set of material properties that are assigned to the finite elements that surround each fuel particle. In this way the effective thermal conductivity of the material may also be determined as a function of the volume fraction of the interaction layer. Work is on going to add fission gas bubbles in the fuel as a fourth phase to the model.

According to Legge, Faxian wrote: Proceeding 18 yojanas southeast [from Mathurii and 7 yojemas from Kanauj, which he visited next], they found themselves in a kingdom called Sankasya, at the place where the Buddha came down, after ascending to the Trayatrimsa heaven… The bbirsuni Utpalavarna thought in her heart, "Today the kings ... will all be meeting the Buddha. I am but a woman; how shall I succeed in being the first to see him?" Buddha immediately ... changed her into the appearance of a holy cakravartin king, and she was foremost of all in doing reverence to rum. As Buddha descended from his position aloft in the Trayatrimsa heaven, when he was coming down, there were made to appear three flights of precious steps. Buddha was on the middle. composed of the seven precious substances. The king of Brahma-loka also made a flight of silver steps appear on the right side, where he attended with a white chowry in his hand, Sakra, ruler of devas, made steps of purple gold on the left, where he held an umbrella "" When he was come down, the three flights all disappeared in the ground, excepting seven steps ... Afterwards King Asoka, wishing to know where their ends rested, sent men to dig and see, They went down to the yellow springs [the water table] without reaching the bonom of the steps, and from this the king rceived an increase to his reverence"" [Asoka] built a vihara over the steps, with a standing image 16 cubits in height, right over the middle flight. Behind the pillar, he erected a stone pillar, about 50 cubits high, with a lion on the top of it. Let into the pillar, on each of its 4 sides, there is an image of the Buddha, inside and out shining and transparent, and pure as it were of lapis lazuli [which roared in a later monastic debate], Faxian also reported stupas built later where the nun Utpalavarla knelt, where the Buddha cut his hair, where three previous Buddhas sat, as well as offerings made to a white-eared dragon that continued to protect the monastic community, One gets the impression of a crowded, complex site in the early 5th century, with presumably wooden monastic buildings, Over 200 years later, Xuanzang described visiting the site of the descent from Tryatrima named now)iebita (Beal: "written formerly Sengjiashe") and located less than 200 li southeast from Kanauj (in which Beal suggests he is mistaken on the direction), His account reads: Some centuries ago the ladders still existed in their original position, but now they have sunk into the earth and have disappeared. The neighboring princes ... bujlt up of bricks and chased stones, on the ancient foundations 3 ladders resembling the old ones. They are about 70 feet high. Above them they have built a vihara in which is a stone image of Buddha, and on either side of this is a ladder of Brahma and Sma, just as they appeared. On the outside of the vihara, but close by its side, there is a stone column about 70 feet high, which was erected by Asoka-raja, It is of a purple color, and shining as if with moisture. The substance is hard and fmely grained, Above it is a lion sitting on its haunches and facing the ladder. There are carved fig-ures inlaid, of wonderful execution on the four sides of the pillar and around It Xuanzang also records other stupas commemorating Buddhas of the past and the nun Utpalavatma, now eclipsed by Subhoti who had already seen the dharmakaya in the form of the doctrine that all existing things are void of reality, Again, we get a picture of a bustling monastic community in the 7th century. And the resplendent lion pillar with Buddha images stands out in both accounts, On the basis of the name Sankasya, known from the pilgrims and from texts like the Divyavadana, as well as the general location, Cunning-ham identified the modern village Sankfsa in modern Farrukhabad district, up. with the site of the Descent, It lies some 40 km. northeast of Kanauj in the Doab, richly populated with ancient remains, The two Gupta sites Jankhat and Bilsadh took me to this area in 1974, Cunningham included the site in his reports for 1862 and 1876. In the first he recorded the presence of an ASokan capital and worship of a naga named Karewar, which he identified with Faxian's description. In 1876 hecollected objects reproduced on the right. I know these only from this abysmal image and would be delighted to hear that they survive in some museum. Cunningham suggested that #2, a fragment of a tiny soapstone disc, represented the site itself, with a seated Buddha and kneeling Utpalavarna at the top of what survived. The Archaeological Survey of India returned to this site ten years ago and excavated here for at least 2 seasons, as reported in Indian Arcbaeolo-gy, A Review for 1995-96 and 96-97, finding Painted Grey Ware, Northern Black Polished Ware, Sunga, Kushan, and Gupta pottery, pre-Kushan bricks, and terra-conas attributed to the Gupta period, The Aokan capital found here has continued to receive attention. Is this what both Faxian and Xuanzang described as a lion? Cunningham asserted that both were mistaken about the identity of the animal, It might be pointed out that the shorter pillar that stands at the site of the Parinilvana makes some confusion plausible, Xuanzang describes the pillar standing at Sarnath as "bright and shining as a mirror: its surface is glistening and smooth as ice, and on it can be constantly seen the figure of Buddha as a shadow," I. e" he ignored the form of the capital and was mesmerized by the stone's polish, It is also possible that the Buddha figures he mentions here and Sa:nkasya were in fact carved on the pillar like the Gupta pillar at Kahaum, which has four TIrthankaras at the top as well as a single one below. The elephant capital has continued to attract attention for the excep-tional swirls beneath what was long considered a lotiform bottom to the capital, John l1win took these to indicate that the "lotus" in fact originated as a piece of cloth draped over a wood

Commitment to Sport and Exercise: Re-examining the Literature for a Practical and Parsimonious Model

Williams, Lavon The Korean Society for Preventive Medicine 2013 Journal of Preventive Medicine and Public Health Vol.46 No.suppl

A commitment to physical activity is necessary for personal health, and is a primary goal of physical activity practitioners. Effective practitioners rely on theory and research as a guide to best practices. Thus, sound theory, which is both practical and parsimonious, is a key to effective practice. The purpose of this paper is to review the literature in search of such a theory - one that applies to and explains commitment to physical activity in the form of sport and exercise for youths and adults. The Sport Commitment Model has been commonly used to study commitment to sport and has more recently been applied to the exercise context. In this paper, research using the Sport Commitment Model is reviewed relative to its utility in both the sport and exercise contexts. Through this process, the relevance of the Investment Model for study of physical activity commitment emerged, and a more parsimonious framework for studying of commitment to physical activity is suggested. Lastly, links between the models of commitment and individuals' participation motives in physical activity are suggested and practical implications forwarded.

Regulating Prperty and Liability Insurance Rates Through Excess Profits Statutes

Williams Jr., C . A . 한국보험학회 1990 保險學會誌 Vol.35 No.-

Excess profits statutes in six states require automobile insurers to return excess profits, if any to their policyholders. This article discusses the issues that must be resolved in drafting and implementing an excess profits statute. For example, what is the long-run reasonable of return? What allowance should be made for short-run fluctuations around the reasonable rate af return? The article also examines carefully the only two statutes (Florida and New York) that have been implemented to date. Finally, it presents the cases for and against excess profits statutes as a supplement to existing forms of property and liability insurance rate regulation.
