The Advanced Test Reactor Fresh Fuel Shipping Container (ATR FFSC) is currently licensed per 10 CFR 71 to transport a fresh fuel element for either the Advanced Test Reactor, the University of Missouri Research Reactor (MURR), or the Massachusetts Institute of Technology Research Reactor (MITR-II). During the licensin…
This paper examines the difference between infinite and finite domains of a Stefan Problem. It is pointed out that attributes of solutions to the Diffusion Equation suggest assumptions of an infinite domain are invalid during initial times for finite domain Stefan Problems. The paper provides a solution for initial an…
The C 60 fragmentation induced by nanosecond (ns) laser was studied using a time-of-flight mass spectrometer. The average kinetic energies of fullerene ions C 60-2n + (1≤n≤14) was extracted from the measured full width at half maximum of ion beam profiles. The measured data show approximately linear increase with the…
The Idaho National Laboratory (INL) has been researching the application of solid-oxide electrolysis cell for large-scale hydrogen production from steam over a temperature range of 800 to 900ºC. The INL has been testing various solid oxide cell designs to characterize their electrolytic performance operating in the el…
The Next Generation Nuclear Plant (NGNP) Project is tasked with selecting a high temperature gas reactor technology that will be capable of generating electricity and supplying large amounts of process heat. The NGNP is presently being designed as a helium-cooled high temperature gas reactor (HTGR) with a large graphi…

A study was conducted to perform magnetic resonance imaging (MRI) measurement of dynamics of the liquid and dissolved gas during acoustic cavitation. The study focused on obtaining information on dynamics of molecules that constituted the bubbles and the surrounding liquid. The information was acquired directly using…
A study was conducted to demonstrate the finite element modeling of micro cantilever excited by the fluid force. The micro cantilever in the existing model was excited by a fluid pressure force created by the fluid flow. COMSOL Multiphysics was used to develop the model involving the use of 3 different modules. The th…

본 연구에서는 활성탄의 중금속 흡착능을 증진시키기 위한 방편으로 hydroxyapatite를 활성탄에 적용하였으며, 적용된 흡착매질을 이용하여 중금속 흡착에 관한 동역학적 연구 및 기초 연구를 실시하였다. Hydroxyapatite의 첨가량이 0∼30%로 증가하면 Cadmium의 제거(주입농도; 50㎎/L)는 초기 20분 동안에 급격하게 일어나 240분 후에 평형에 도달하였으며 흡착율은 각각 50.2%, 73.7%, 94.4%와 98.2%와 흡착량은 6.90㎎/g, 10.30㎎/g, 13.19㎎/g, 그리고 13.72㎎/g으로 조사되었다. 또한, hydroxyapa…
Different parameters that can modify the extension of the transesterification reaction have been evaluated, such as, reaction temperature, agitation speed, methanol:oil molar ratio, percentage of solid catalyst presents in the reaction medium and percentage of sodium incorporated into the catalyst used.
A methodology called the Multi-step Approach to Code-coupling for Progression Induced Severe Accidents in CANDU nuclear power plants (MACPISA-CANDU) was developed and applied. MACPISA-CANDU was used to couple a MATLAB single fuel channel model with a primary heat transport system model developed in MELCOR (MELCOR 1.8.…
Understanding the radiolytic degradation behavior of organic molecules involved in new or existing schemes for the recycle of used nuclear fuels is of significant interest for sustaining a closed nuclear fuel cycle. Here we have conducted several lines of investigation to begin understanding the effects of radiolysis…
Abstract : This work aimed to test the hypothesis that MR guided pulsed HIFU exposures enhance gene delivery and increase the efficacy of gene therapy in inhibiting prostate cancer growth in vivo, particularly when combined with AD or RT. We developed techniques for the treatment of prostate tumor-bearing mice using a…
The objective of this project is to lay the foundation for using ordered nanoporous materials known as metal-organic frameworks (MOFs) to create devices and sensors whose properties are determined by the dimensions of the MOF lattice. Our hypothesis is that because of the very short (tens of angstroms) distances betwe…
본 연구에서는 전자산업에서 주로 사용되는 invar 강판재료를 식각한 후 생성되는 FeCl₂을 FeCl₃로 환원하여 회수한 후 재사용하기 위한 식각액 재생공정에서 FeCl₃의 회수 농도와 재생공정의 단수와의 관계를 규명하고 원하는 FeCl₃ 회수 농도를 얻기 위한 공정의 최적단수를 얻어낼 수 있는 simulation program을 개발하였다. 이 프로그램을 위한 여러 가지 parameter는 pilot 실험을 통해 얻었다. 개발된 프로그램에 의한 공정 모사는 폐액의 발생량 및 처리비용을 극소화할 수 있다. 또한 개발된 프로그램은 원하는 FeCl₃의 농도를 얻기 위…
Cast iron (CI) is one of the oldest materials in commercial use. It has excellent compressive strength and is commonly used for structures that require this property, as well as for water and sewer lines. This article explains CI metallurgy and why the understanding of this metallurgy is key to understanding other fer…
La siguiente investigación fue realizada con el fin de encontrar un sistema, de diversos aditivos\nno halogenados, que funcionasen en favor de la reducción de la capacidad de quemado del XPS\n(espumas de poliestireno extruido), ya que los sistemas halogenados, muy pronto dejaran de ser\nuna elección viable por las ley…
The catalytic amination of n butylamine and methanol, which is high in atom utilization, was conducted to produce N, N-dimethyl-n-hutylamine economically and environmentally. The catalysts were prepared by impregnation of Cu, Ni, Co on the phosphoric acid treated γ-Al2O3 and the processes were studied in a tubular fix…
소량의 인듐이 첨가된 치과용 Au-Ag-Cu-Pd 합금의 상변태와 미세구조의 변화를 경도시험, X선회절 실험, 전계방출주사전자현미경 관찰 그리고 에너지 분산형 엑스선 분광분석을 시행하여, 다음과 같은 결과를 얻었다. 시효 초기에 경독 잠복기를 거치지 않고 빠르게 상승한 다음 완만히 상승하여 최고 경도에 도달하였고 최고 경도를 일정기간 유지하고 나서 서서히 하강하였다. 용체화 처리한 시편을 등온시효 처리한 결과 단일상인 α 0 상이 Au-Ag-rich α₁상과 AuCuⅠ상 그리고 Cu와 Zn이 고용된 InPd상으로 변태하였다. 시효 초기의 경화는 입내에서 AuCu Ⅰ…
