This report fulfills the M4 milestone, M4FT-15IN08020110 UNF Analysis Support, under Work Package Number FT-15IN080201. The issue of materials selection for many engineering applications represents an important problem, particularly in cases where material failure is possible as a result of corrosive environments. For…
Stahlbänder werden für ihren Transport zur weiteren Verarbeitung generell geschützt, im einfachsten Fall wird das durch eine Beölung der Oberfläche realisiert. Die Verwendung von Öl hat jedoch Nachteile aufgrund einer mangelnden Haftung auf der metallischen Oberfläche und der damit verbundenen Verunreinigung der Lager…
No presente trabalho, foi feito um estudo sobre o cimento asfaltico de petroleo CAP, envolvendo a sua modificacao pelos polimeros termoplasticos polietileno de alta densidade (PEBD), polietileno de baixa densidade (PEBD) e polietileno linear de baixa densidade (PELBD), os dois ultimos de diferentes grades, e o estudo…
The ATF Implementation Plan integrates DOE’s objectives and goals with the national laboratory’s expertise and infrastructure in support of the technology development by three industry partners. DOE’s plan is to develop advanced LWR fuels with enhanced accident tolerance in response to the Congressional request and to…

Background: Nanoparticles are increasingly suspected as a strong etiologic factor in sarcoidosis pathogenesis.The aim of our study was to evaluate lung inflammatory response and histology changes following exposure of mice to two types of nanoparticles: carbon nanotubes (MWCNT) and cadmium-based nanoparticles (QDOT705…
Electron beam melting (EBM) has been used to manufacture Ti-6Al-4V micro-truss materials for light weight mechanical applications. Several structures were examined, including a cubic lattice, a diamond structure and randomly-structured foams. The “As-built" material, after the selection of processing parameters and fa…
The objective of this study is whether or not cerium dioxide (CeO2) nanoparticle has the pulmonary toxicity. We performed inhalation and intratracheal instillation studies using same sample of cerium oxide nanoparticles, and examined the pulmonary inflammation in both studies. In intratracheal instillation study, rats…
Background: Silica is the common name for silicon dioxide (SiO2) materials and exists in both crystalline and amorphous forms. While crystalline silica is known for its severe health effects, amorphous silica has been considered safe and applied in many areas. However, some recent studies have showed evidence of their…
Nepheline (NaAlSiO₄) crystals can form during slow cooling of high-level waste (HLW) glass after it has been poured into a waste canister. Formation of these crystals can adversely affect the chemical durability of the glass. The tendency for nepheline crystallization to form in a HLW glass increases with increasing c…
The patency rate of small diameter synthetic bypass grafts remains poor. The aim of this study was to develop a biocompatible, acellular, arterial scaffold, assess the scaffolds regenerative capacity using ovine vascular cells and begin preliminary studies of a vascular tissue bioreactor for the development of a tissu…
Wax formation in diesel and biodiesel fuels at low temperatures is one of the major problems faced by the fuels industry as crystallisation of the saturated compounds present in these solutions can plug up filters and obstruct pipelines. Preventing wax formation in these multicomponent mixtures requires a good underst…
This progress report describes work being done at Sandia National Laboratories (SNL) to assess the localized corrosion performance of container/cask materials used in the interim storage of spent nuclear fuel (SNF). Of particular concern is stress corrosion cracking (SCC), by which a through-wall crack could potential…
Ultracapacitors (UCs), also known as Supercapacitors or double layer capacitors, are the promising technology devices used for storing energy in the field of energy storage systems. These ultra-capacitors, being a low voltage device, provide fairly large capacitance values as compared to the conventional capacitors. T…
Jason Cong received his B.S. degree in computer science from Peking University in 1985, his M.S. and Ph. D. degrees in computer science from the University of Illinois at Urbana-Champaign in 1987 and 1990, respectively. Currently, he is a Chancellor's Professor at the UCLA Computer Science Department and the director…
Problem of empty cavity dynamics in a two-phase medium is considered. The initial equilibrium state of “cavity-medium” system is disturbed when pressure inside cavity falls abruptly up to 0. Rarefaction wave arising on an interface initiates a cavitation development. Two-phase mathematical model is applied to investig…
One of the current challenges in the field of metamaterials is to extend beyond electromagnetism in other areas such as acoustics [1]. Soft matter techniques coupled with microfluidics provide a unique tool to take up this challenge because they allow for the production of 3D locally resonant (random) materials compos…
Applying current guidance and practices for common-cause failure (CCF) mitigation to digital instrumentation and control (I&C) systems has proven problematic, and the regulatory environment has been unpredictable. The potential for CCF vulnerability inhibits I&C modernization, thereby challenging the long-term sustain…
A series of Advanced Gas Reactor (AGR) irradiation experiments are being conducted within the Advanced Reactor Technology (ART) Fuel Development and Qualification Program. The main objectives of the fuel experimental campaign are to provide the necessary data on fuel performance to support fuel process development, qu…
This document explores startup fuel options for a proposed test/demonstration fast reactor. The fuel options considered are the metallic fuels U-Zr and U-Pu-Zr and the ceramic fuels UO2 and UO2-PuO2 (MOX). Attributes of the candidate fuel choices considered were feedstock availability, fabrication feasibility, rough o…
