Significance and Use 5.1 This test method is normally used to evaluate flat specimens from finished items of protective clothing and from materials that are candidates for items of protective clothing. 5.1.1 Finished items of protective clothing include
The Design Demonstration Experiment for the University of Missouri Research Reactor (DDE-MURR) is intended to facilitate Low Enriched Uranium (LEU) conversion of the MURR by demonstrating the performance and fabrication of the LEU fuel element design through an irradiation test in a 200mm channel at the Belgium Reacto…
Abstract : A novel series of scripts have been written in order to dramatically simplify the computation of the U.S. Army Research Laboratory (ARL)-developed crystalline density and heat of formation prediction tools required for the evaluation of performance properties for notional energetic materials. Previously, ob…
Post-irradiation examination (PIE) is in progress on coated particle fuel compacts from the first Advanced Gas Reactor irradiation experiment (AGR-1). The AGR-1 Post-Irradiation Examination Plan, INL/PLN- 2828/Rev. 1, includes safety testing of the irradiated compacts in the Oak Ridge National Laboratory (ORNL) Core C…
Legacy computational reactor physics software tools and protocols currently used for support of Advanced Test Reactor (ATR) core fuel management and safety assurance, and to some extent, experiment management, are inconsistent with the state of modern nuclear engineering practice, and are difficult, if not impossible,…
The microstructure of Advanced Gas-Cooled Reactor (AGR) fuel cladding that underpins its corrosion behaviour has been established, contributing to an understanding of long-term control, monitoring practice and storage decisions for this fuel. AGR fuel cladding specimens sourced from Sellafield Ltd, cut and individuall…
year. This summer, the MAaD Pathway invited subject matter experts to participate in a series of workshops which developed the basis for the research plan of these DOE R&D NDE activities. This document presents the results of one of these workshops which are the DOE LWRS NDE R&D Roadmap for Reactor Pressure Vessels (R…
GaN nanowires were created from planar GaN epilayers using a top-down fabrication technique consisting of a dry etch followed by an anisotropic wet etch.The GaN nanowires are m-plane bounded with tightly-controlled dimensions.Single-mode lasing was achieved with GaN nanowire with 130 nm diameter and 5 μm length.Numeri…

Preliminary system models have been developed by Idaho National Laboratory researchers and are currently being enhanced to assess integrated system performance given multiple sources (e.g., nuclear + wind) and multiple applications (i.e., electricity + process heat). Initial efforts to integrate a Fortran-based simula…
The structures of a variety of disordered materials were determined using the technique of total neutron scattering. The synthesis of various polymorphs of Ga2O3 and related materials was investigated and the structures of the hitherto uncharacterised polymorphs were examined in detail. The structure of y-Ga2O3 was fo…

Significance and Use 5.1 Differential scanning calorimetry provides a rapid method for the determination of enthalpic changes accompanying first-order transitions of materials. 5.2 This test method is useful for quality control, specification acceptance,
Diatom, as a kind of autotrophic photosynthetic eukaryotic algae, is an important primary producer in aquatic ecosystem, and can reflect the average status of water environment. As the bio-indicators of the environment, Nitzschia communis, Navicula minuscula, and Gomphonema parvulum can indicate the eutrophication of…
One of the events postulated in the hazard analysis at the Waste Treatment and Immobilization Plant (WTP) and other U.S. Department of Energy (DOE) nuclear facilities, is a breach in process piping that produces aerosols with droplet sizes in the respirable range. The current approach for predicting the size and conce…
The Department of Energy s (DOE) Light Water Reactor Sustainability (LWRS) Program is a five year effort which works to develop the fundamental scientific basis to understand, predict, and measure changes in materials and systems, structure, and components as they age in environments associated with continued long-ter…
Arrays of encapsulated bubbles have been shown to be very effective in reducing underwater sound radiated from various sources [J. Acoust. Soc. Am. 131, 3356 (2012); J. Acoust. Soc. Am. 131, 3506 (2012) ]. These arrays have been used to treat both sources of noise and to protect a receiving area from external noise. T…
Originally demonstrated with electromagnetic waves, supercoupling describes the extraordinary matched transmission, energy squeezing, and anomalous quasistatic tunneling through narrow channels. This behavior is the result of impedance matching achieved when the effective properties within the channel approach zero. F…
Bio-based thermoset composites were prepared from epoxidised linseed oil (ELO) using bio-derived crosslinkers. The use of Pripol 1009 (a dimerised fatty acid derived from natural oils and fats) as a crosslinker yielded homogenous transparent films. The inclusion of catalysts, in particular, 4-dimethylaminopyridine (DM…
This research is aimed at understanding the effect of thermal cycles on the metallurgical and microstructural characteristics of the heat affected zone of a multi-pass pipeline weld. Continuous Cooling Transformation (CCT) diagrams of the pipeline steel grades studied (X65, X70 and X100) were generated using a thermo…
